Does anyone know if you can buy a lead with a Tamiya female connector and lightning male connector?
I ask coz I want to use my I-phone for Google maps as sat nav and the obvious power supply on the mighty Speedtriple is via the Tamiya connector that exits from the LH side of the tank

I’m off on a trip down to Newquay ( Cornwall ) on Saturday and want to bag the Devon tags on the way there and the way back, without using Motorways ( coz they’re boring ) and it’s a bit convoluted, don’t usually...

Me again :roll:

I've found that when accelerating hard in gears 4-6 there seems be a strange 'flat spot' around 6 - 7k rpm, the engine note changes and though the speed continues to rise the revs seem to pause around this spot, almost like hitting a limiter, and even fall back slightly (e.g. 7k down to 6.5k) whilst I'm still hard on the throttle, then continue on upwards.

Is anyone able to shed any light on this, maybe Tango or NeilM ?
I'm not 100% there's actually a problem, maybe I'm just...

can any one tell me what carbs will fit my 2003 honda xr125, is the cg carb the same mine has decided it would rather spit the petrol over the road than in to the engine

Hey all.

Was hoping you might be able to help me out? My motorbike shows no sign of power. Turning the ignition turns does not turn on any of the electronic display or the lights. The battery is fully charged. The bike makes an odd buzzing noise. Any help would be greatly apreciated as I am at a complete loss as to what's causing this. Cheers.

Just looking for some light guidance..

We assumed I needed to go bigger on the jets, my main was 135 and pilot was 40...

I have seen online from TJ BRUTAL who know these bikes inside out, for a VLX that is running straight exhaust and modified air intake he suggest 142 or 145 on main and 42 or 45 on piliot. I was thinking 142 and 42 as I had some air resistance, running foam pods (not straight velocity stacks).

Would anyone agree with me on this, want to try nail it right on first time....

So I thought it would be a good idea to fit a quick throttle, which involved removing the air box to get to the other throttle cable adjusters. Anyway, the problem is, a bolt had seized and had to be drilled out (I rounded the head, then EZ outed it, which snapped it half way down) and as a result, and because of where the bolt was located, I think a bit of metal shavings and/or grit (the air box was dirty) has entered the engine.

Having a look with the throttle open, I can see a few grit...

Any ideas? On my cbf1000, within the last week, the front nearside indicator has stopped working and the rear has started flashing really quickly. Definitely not the front bulb and I don't think it is the connections to the front. I know that the front worked and the rear flashed normally last week because a friend was showing me what to check, POWDERSS.
Any help gratefully received

Could any one help me with my problem
My bike is a 1997 zx6r F3 35k blue flame exhaust but the rest is standard
Have owned the bike since 2008 and the only issue I had was a slight flat spot at 4k due to the blue flame exhaust.
So, my problem is as follows the bike stood for 18 months with the odd starting up. So, went to put it on the road this summer and low down up to 4k it ran awful after 4k it was ok, difficult to start.
So, I serviced the bike.
New plugs air filter fuel filter, fully...

This... *lovely* ZZR 600... This AMAZING bike of mine...

I hate it already.

So, I did something stupid. I was low on fuel before the MOT, so naturally I felt it would be a good idea to fill up a petrol can without checking the contents. It must have had some crap inside because the bike started complaining when going over 65mph, which you can guess how that is on a motorway. The slowdown and sudden acceleration was a little off putting.

It got better with a bit of premium unleaded, but...

Hello everyone, so long story short my YBR's top end is just a bit lacking. It will happily sit at 50mph and will push to 60mph. I would prefer if it could happily sit at 60mph and push to 70mph. The only real mod I could find for this bike without spending serious money was an eBay 150cc kit for around 80euro. I think it will probably be a bad idea to buy it but kind of hoping I'm wrong, so if anyone more knowledgeable than me could shed some light that would be great :)

I also don't want to...

My bike is finally built, new battery coming today and pretty much good for the MOT.

We seem to think my bike sounds better when the choke is open, meaning it could be running lean/rich etc. So I need bigger jets?

I have a good idea of what I am after as advised by someone who knows these bikes inside out.

Is there a shop online or not based in the UK i could call for these puny luttle bits of brass?

Looking for some advice on something a little strange that happened today.

Riding through town around midday, it was hot and was in stop/start in traffic. Fan was cutting in and out as it should and was working fine. Then the engine warning light came on. There was no performance drop or anything of not. It stayed on for around 5 mins until I was outside oftown and as soon as I got above 30mph the light went out and never came back on. I ran the diagnostic mode when I got home and nothing...

The actual switch button thingy came off my hazard switch yesterday during a bit of a do. :oops:

I can't see anything has snapped, it would appear to be a case of gluing it back on. Is this correct and what adhesive do I need? Is it just a superglue job?

Thanks

I have a problem with my 125cc. I can put it in first and it rides well but then when i come to a stop and drop it to first it completely stalls and takes a few mins to turn back on.
Any help on this would be great.

Sorry if this post is in the wrong place not sure where to put it.

Hello all first post ever on a forum from me so sorry if I'm doing something wrong.
I have a honda CBR125 2012 model. I came across a problem a while ago, I went to turn the key on in the evening and nothing happened. No fuel pump sound, no lights, no horn, no dash startup, no neutral light.
I just bought a new battery also so I found this awfully weird. I checked the battery connections and they was fine so I went to try and bump start it. I failed the first two times but after the second...

Right guys, it seems the end of my woes is not the end yet.

Bought a second hand NSR 125 off eBay for a grand, tested bike at purchase and all was a-ok apart from an oil leak.

Took it to a Honda garage down the road the day after and they said the oil tank had split. Being a 2-stroke the cost was at £250. A few days later they come back and say the rectifier was dead and the battery wasn't charging. Another £120. Fitted a new rectifier yesterday and the battery still wasn't charging - another...

Dropped my newish cbf1000 doing slow speed practice in a car park. :oops: :cry:
Apart from the heart ache and the fact that I bent the rear brake pedal, I also lost some fluid from these hoses which run down the sidestand in the picture. The fluid only came out whilst the bike was on its side :crybaby:
Clutch brakes seem ok. Any thoughts what this was?
Thanks

Can anyone tell me how much 10w/40 semi synthetic oil ( 1 litre of 1/2 litre etc) I need to service my AJS JS125-E ECO 1 motorbike please?

Hello, Can anyone point me to a good diagram showing the air mixture and fuel mixture screws on the carburettor of this model please. The book that I have on Chinese/Japenese 125cc motorcycles is as clear as mud and I have located one screw on the side (right side of bike) that adjusts idle speed or, is it air/fuel mixture?, but, have no idea if it is air or fuel and how one is supposed to adjust either?

I'm not sure if this the right place to post this but I am having trouble with my Yamaha MT-125 2017. Few months ago I ended up braking down due to corrosion inside the alternator socket which led to a flat battery. I had RAC clean the corrosion and fix the issue but I ended up with a engine warning light. I have contacted Yamaha and they believe it's displaying due to low voltage when I broke down and just needs resetting (doesn't display an error under ODO) but.. the closest Yamaha Dealer is...

My indicators are flashing WAAAY too fast. Well over the prescribed 1-2 flashes per second. Ive checked the bulbs are working- they are. Wot to do next?
Any suggestions appreciated.

Hi guys, having had good advice on this forum before I am back again with another problem.
Having had my Renthal bars fitted by an experienced mechanic my hi beam and low beam headlights are no differenent, i.e. the high beam is no higher than the low beam? Strange I know but the guy says he did not change the wiring in the headlight assembly and all I have done is to fit two new H11 Osram Nightbreakers.
Now I did not remember seeing this problem with the old bulbs in it after the bars were...

I'm really not a mechanic so please go easy on me!
I own a kawasaki gt550 and the other day as I was riding home, the bike all of the sudden started to run on only two cylinders.
The coils on my bike run to cylinders 1/4 and 2/3, It is cylinders 2/3 that stopped firing.
I wasn't getting a spark from either plugs 2/3, but when i swapped the wiring of the coils over, I got a spark, so there's no problem with the coils.
I then tested the wires that lead from the cdi unit to the coils, and all...

I have a 2011 lambretta evolution with a lexmoto 125 4 stroke engine

Father replaced air filter before it came down to me with a orange triangle looking thing

No every now and then when I am caning it - it can splutter and stall - I wait 10 seconds - and it starts right back up again!

Is this something to do with the carb/ air / fuel?

Will a tinker with the fuel nut help at all? is it too tight or loose do we think?

Someone said I need the jets altering to account for the new filter but...

Can anyone help, trying to get an XJ900S working that is getting refurbished and not sure which colour of wires to connect to the coils from the loom just to confirm as I can't get it to turn over, pictures would be great.
Thanks

Morning folks,

Small issue with a new ('18) MT-07. Less than 1k miles.

If I align the chain using a laser alignment tool on the rear sprocket, so that it is perfectly aligned, the wheel alignment on the bike is off. This is verified not only by the marks on the swingarm but also by simply noting a veer off to the right when letting go of the bars on an flat road.

Conversely, If I align the rear wheel to the front (using various methods, although the swingarm marks appear fairly accurate for...

New bike comes with a nice loud alarm as standard, which is always nice for the insurance..

However the bloody thing is so sensitive, i store it outside under a cover and if it's really windy and the cover moves at all, alarm goes off! Now the problem being if i know weather is bad, i turn the alarm off. But this brings it's own series of problems.

Anyone else have similar issues? How do you get around them? My only thought was to put some bungie coards around the bike/cover to prevent...

Any advice would be greatly appreciated!

I split my fuel pipe yesterday so I replaced it with some pipe from a bike shop although it was thinner the guy assured me it would be ok.
Today on a ride my bike stopped like it had run out of fuel, on closer inspection the pipe had kinked twice quite bad and the fuel wasn’t getting through.

I’ve replaced it was a thicker pipe just although is still a kink in the pipe.
I can’t see how I can get around this especially due to the angle of the to ends...

Hi
I have an issue with my 600 bandit. It's currently been sat in my garage for about 6 months or so since I last used it. I tried to get it running last weekend and it won't acknowledge me turning the key. Like the battery is flat but it's not that because the battery is fine and charged. Every now and again the needles on the clocks move forward and backwards as they should but nothing comes of it. I'm assuming it's just a loose connection somewhere leading from the battery. Don't suppose you...

I have a 1973 to 500 yamaha motorcycle when I kick it over I only get spark on one spark plug

Hello guys! I need some help with my honda. I need to know which wires do i need for ignition. Now i have b/r which comes from motor to cdi and then i have black/yellow that goes right into ignition coil from cdi. Do i need something else? And i have ground wires too. And are here all the parts for ignition. CDI, ignition coil, stator and sparkplug.

I would be pleased if someone could answer this :)

Hi guys,
so i recently bought a Bullit Hunt s 125, brand new from a motorcycle and scooter center, it was delivered on 05/01/2017 and was working fine. fast forward to sunday this week, so 15/01/2017, i haven't been able to ride the bike yet and only just got it insured the night before. i go to get on the bike, turn the ignition key and nothing happens. no lights, starter button won't work, nothing. so i put the battery on charge and leave it. the next day i reconnected the battery and it...

Hi my bike has it's first service and MOT coming up but I'm a bit precious about it and don't want to leave it with just anyone.

Can anyone recommend anywhere around the Stamford/Peterborough area?

I’m having a problem with my Honda cbf 125 2013 model.

When driving my bike it dies after like 1 minute of driving in parkinglot speed, no power at all. I turn the ignition off, and wait for 1 minute and turn the ignition on again and it starts. When the bike dies there is no power at all, no lights or dashboard lights.

When the bike is ideling it somtimes revs up to 3000 rpm and engine light turns on. After like 2 seconds it goes back to normal and engine light turns off.

I have no clue...

Hi. Ended the weekend by popping some wheelies (off road) on my wr250x. The clutch engaged then suddenly it was like it had slipped into neutral, even though the neutral light wasn't on. I tried to get the bike moving in any gear and got nothing but revs. It would crawl about 2mph in 1st. I have just changed the clutch plates thinking it would solve the problems. Started the bike fine, no strange noises and still nothing even with clutch fully engaged. Anyone have this happen before? If so,...

Hi

My bike feels like the back wheel is loose, I feel as if the back end is twitchy.
Wheel nuts are tight, can anyone suggest anything to check ?

Alan.

Anyone had a problem with a Kawasaki GTR1400 repeatedly blowing the regulator rectifier?

I'm onto my third regulator/rectifier in 18 months.

The first time it failed I had a fluctuating voltage and flickering headlights (intermittent) followed by sudden complete power failure (blew main fuse).

Second one lasted 15 months and then the voltage started to fluctuate again and flickering headlights. Voltage would go up to 15.5 and down to 10v. Got it replaced (and new battery), but voltage...

Hello!

I am new here so please forgive me if i have posted in the wrong place.

So, i have a Suzuki Gz125 and i just replaced the carb (mikuni) diaphragm because it had around 7 small holes in it and now the bike starts and idles just fine but bogs down when triyng to rev it up. If i am patient and careful and i get it over that bad spot on the throtlle i can redline it but once i go beneath it happends again. I think it might be running rich. How i can fix this? Adjusting the needle jet?...

Bought a new battery for the bike, filled it with the liquid supplied but I have no way of charging it for the first time. Is it essential to charge it? Or should I stop being a cheap skate and just buy a bike charger?

I went for a test ride on a 1994 KLR250 today. The bike is in reasonably good condition and the engine and gearbox seem pretty tight. The only real issue is that the bike stalls without choke so the carby clearly needs some attention.

It runs fine on or off choke under power and normal riding conditions, just not at idle without choke. I only test rode it for about 10 mins, but I am pretty sure that was enough time for the engine to be at running temperature.

Any comments appreciated.

Ive been building a cafe racer out of a 1982 cb400n
Ive put a new brake lever and new braided hoses on it i bought some second hand calipers which are in really good condition, ive filled the system with fluid and bled the calipers but my lever still squeezes to the grip, ive nearly pushed a whole bottle of fluid through them and im still getting tiny air bubbles
Any ideas whats going wrong?
All the fittings banjo bolts etc are new

Hi guys hoping someone might be able to help me i have an 82 kawasaki ke175
Its running like a bag of snot it used to run ok now it will only start on full throttle and just about idles full throttle let go of the throttle and it dies,
The over flow was leaking on the carb so i thought could be the problem, i changed the carb and its still exactly the same, did a compression test it was fine, took the cylinder off and the piston rings etc look fine,got so fed up ive with it ive listed it on...

More of a rant than a question!

Right hand fork seal has gone on the GSA. 8k miles.

Also the amount of rust which is now appearing is just appauling! It doesn't get ridden in the salt (Fair weather biker! :oops: ).

So yeah, BMW, Your build quality sucks. A lot.

End rant.

Firstly, I know nothing about bikes, and this is the first I bought. It is a 16 plate that started fine when I bought it a few weeks ago. I garaged it as have not done my CBT yet. I went to start it the other day and it would turn over but not start. Then read about the side stand switch, so put the stand up and away she went. Few days later, turned the key and no lights etc so spoke to a mate who suggested I get a trickle charger, which I did. Now the charger shows the battery charged and the...

Ok, so I got a gsx-s750, the problem being is that the handle bars are 30mm in diameter, and I have had a screw snap from one of the bar ends, I did drill 90% of it out, then the drill bit snapped. So I can’t find for the life of me, a 30mm bar, all 22mm. But I have seen a pro downhill mountain bike flat bar, that is basically what am looking for, my question is will this be safe on my motorbike??? Or so I get a riser and have a 22mm bar?? It’s driving me mad.
Thanks in advance
Rob

Sod the Royal wedding, we have fork seals to do.

Definitely too far gone, so let's wipe the stanchions and see the state of the chrome.

20180519_121926.jpg

Great, so even if I get this job done, the pits will nic at the new seals and ruin them before I even begin.

Also, how the hell do you get these off the top? :crybaby:
I have never seen these on top of forks.

HI, new to the forum, i signed up because i can't really find an answer to this question.
Basically i have a 2003 GZ 125 and am having problems with the carb, i'm looking at a new one on ebay but they all say they are only for bikes without a TPS, well mine has a TPS and the only one i can find with a TPS is £130 used, almost triple the cost of a new one without. Now i don't really understand how a TPS works but if i get the carb WITHOUT tps, can i just remove the cabling and use the bike...

Have had two friends contact me today with possibly the same problem. Bike misfires, horrible noises, bike stops. Oil drained and loads of iron filings in it AND SMELLS OF PETROL. Anybody else?
