An odd fault on my 2005 FZ6.

The voltage on the battery is fine 13.5v at idle bring the revs up at the current drops of till the volts are 10-11v which is below that of the battery at rest 12v.

An suggestions as to cause?
Diode test on the Rectifier that seems fine,
Ohms check on stator again that seems fine.

Just as the revs build the volts fall away...

Please help, I recently purchased a 1982 Honda XL 500, lovely bike but I am having real trouble starting. I have gone through many start up procedures but keeping getting a kick back.
It has a decomp lever that seems to make things worst. I just need a reliable way to start the bike. Any advice will be welcomed. Thank you

Hi everyone,

I've been looking into alternatives to the OEM chinese things on my 125, i found this thread from last year:

where folks are talking about ContiGos - but Continental don't seem to think they do a ContiGo in the 'right' sizes, which is an 80/100 18 at the front and a 90/90 18 at the back:

Would i just put the 2.75 18 on the front and the 3.00 18 on the back in that case? are they basically close enough to the original sizes that it won't be noticeable?

Cheers!

Morning all, I have just got a suzuki tlr which I'm going to keep in the garage till summer next year any advice on best storage methods or tips etc. The battery is fitted with a otomizer, has fuel in the tank and front & rear paddock stands too all cleaned and polished.....anything else need doing to it? Tia mike.

I'm looking at getting a 2nd hand 4 stroke 250 KTM enduro bike for riding the green lanes, now I need a bit of advice from any enduro riders regarding service intervals. I know the guys that race these machines are changing oil and filters all the time, I can appreciate that considering how they ride them, if all I'm doing is a bit of green laning, would service intervals be comparable to my road bike? Or do I need to do oil and filter changes more frequently on those machines? Haven't done...

hi
Having issues with my bike, it isn’t the battery as that’s new and has been checked. It starts but at times when I stop off it won’t start again. One garage said it was starter motor the other said starter clutch, difference is £300 plus any ideas? Thanks in advance been trying to sort for weeks!

I have not adequately looked after my Chinese 125. Through ignorance rather than apathy. I changed the oil really quite often but have done nothing about other things. The 'head race' bearing went after only 5600 miles.

Flip side of this. I have a 1990 zzr600 (yay) in good condition. I have bought the Haynes manual for it and plan to follow the servicing advice in it. Are there good things I can do not mentioned in the manual? Does it matter who made the filters that I might replace etc? Are...

Evening all. Back with another problem! When starting my bike i start it up put my helmet and jacket on gloves etc jump on engage first gear and when i go to pull away it seems to go “flat” stutter then when i change into second its fine also sometimes cuts out if i rev it in first then come to a stop. Once bike is running it seems to be fine albeit the odd cut out at lights when idling. I changed the oil to castrol 10w40 and it needed a new coil pack as well which i have since replaced. Any...

Hey all,

I said over in the newbies section I would pick brains so here's the first pick at them :D

I've had the ZZR 2 weeks now and absolutely love it. But definitely needs the suspension setting up to suit my weight and my riding style.

I'm definitely not a suspension guy, I suppose I could make countless adjustments using trial and error but if someone has a one strike formula or setup they are using they can reccomend I would love to hear from you !

Its currently set up very soft, the...

Hi all,

I have a 2001 CBR600 which is totally standard, it purrs beautiful and sings wide open but I would like a sportier note without being track day loud.
I have the broad strokes of decent brands but having a hard time hearing any expect from on videos which do not do them justice.
My predicament, how to I sample them before making a choice?
I’m going slip on not the whole system.
I would like a deeper burble without sounding like a wee fanny in a corsa
Any input/experience welcome...

Hi guys I’m completely new to this and I hope it makes sense🤣
I’ve got a 2012 Honda Cbf125 and I’ve recently sorted the common “kangarooing” problem with the fuel pump.
Around 100 miles later on my commute back into London (just after filling up again since the kangaroo problem) at a set of traffic lights, she cuts out.
I tried starting up again and I had nothing. She is ticking over and she desperately wants to start but nothing!
I tried bump starting it down an absolutely massive hill too...

Hello I'm new to all this stuff so sorry if. You can't understand me. I just bought a speedfight 2 100cc and the starter moter was spinning away. Apon opening the case the bendix was missing and can't fine a replacement anywhere Help do u no wear I can get a bendix gear for a speedfight 100cc please thank

I stumbled upon this today , made me smile.

The boys bike is up for sale and we've had a couple of offers but nothing solid. However because the bike has been standing in the garage for a couple of weeks now I've been starting it and running iit for 5 - 10 minutes every couple of days. So today I start the thing and rev it up then switch off, no problem so I push it out of the garage and leave it out while I tidy up the garage.
An hour or so later I push it back in and decided to try it again. B*@$tard won't start and because I'm now...

Hi I have a 5 year old Enfield Bullet 500 with 10,000 miles. Sometimes the clutch sticks from starting. This morning when I put it into gear, with the clutch in, it jumped forward and when I braked it stalled. After the first time it's good all day. Any idea?

Hi, everyone ive just purchased a Varadero 125,It started with F1 light on all the time, Ive reseated all interfaces and now have F1 flash every 2seconds it also goes into limp mode.
Any Ideas,

Hi all. In the process of eliminating the cause of stuttering with my bike. Generally in low gears at low revs. Developed not so long back so I know it's not just a 'normal' thing with this particular model of bike. (Kawasaki er6n) I'm suspecting the fuel injectors might need a clean now. I'm questioning whether to try a fuel injector cleaner first or just go ahead and removing and cleaning the injectors. Anyone had any experience positive or otherwise with over the counter fuel injector...

When I the bike the sump was full of fuel. As the fuel tap was left on prime I assumed that was the problem. Drained the crap, changed the filter and refilled with new oil. Then noticed all fuel lines to the petcock were disconnected or removed. Haynes doesn't make things too clear so I had to work it all out. Put a couple of litres of new fuel in the tank and she fired up first time. Settled down when warm and ran sweet. Noticed a leak from the out on the petcock so put a new one on and put a...

Hi, I'm wondering if anyone can give some advice because when it comes to electronics on this bike it's just so complicated. Basically the electrics have gone completely dead I've tested the battery thats fine I've tested power to ignition that's fine but when you turn the key nothing... it's just dead no sounds no lights, I've checked around for loose wires ect everything seems to be intact and everything looks in order I've checked fuse box all fuses are okay, I just cant understand why the...

Ok, so I have a 1989 ZX10 b2.
Bike starts ok on the choke, then struggles to tick over unless lots of choke is used.
It revs high then when you reduce choke, struggles to run and sounds lumpy.
The carbs were sonic cleaned and balanced in 2017, by the previous owner. But unfortunately the bike hasn't been used since.
I'm suspecting it's a fuel (carb) issue, where would you start.

Hey everyone not been on in a while I hope everybody is okay, I've been out on my bike not that much, but I couldn't help but notice a whistling sound when I drop gears, I hope it's nothing serious any ideas? Any help would be appreciated.

I've also got an engine light on I'm gonna head down to my local garage also I've not had a service I think it'll be that I'm not sure.

1/ Cable tie on the front shock tells me that I'm using 75% of the travel. Should I think about adjusting? The 2015 CBR500R doesn't have preload adjuster and its the stock spring, so a change would mean some kind of aftermarket part.

2/ He adjusts the handlebar angle to line up with the rider's knuckles. My handlebars have a pin that stops me doing that. Is that the same for most bikes?

Anyone know where I can get a steering stem cap for my 98 Honda CBR 600? Looked in the usual places and can't find any that aren't in the USA.

Cheers
Dave

I recently changed my spark plug on my cb125f (exact same type) and tightened it by manually (according to the manual 1/2 turb then remove it then tighten it 1/8 turn.

When the engine starts from cold, it idles at 1100-1200 rpm but really it should be around 1500 normally. The idling is also rough when cold. Once the engine is warm, it idles happily at 1500 or even slightly higher.

Is this because of how I tightened the spark plug or is it because of a faulty spark plug? Or is it like that...

Hi all. The 10/40 engine oil recommended for my bike is 'semi synthetic'. Okay that's straight forward enough, not 'fully synthetic' then. BUT, the bottle I'm looking at is 'part synthetic.' Would the part synthetic be the equivalent of the semi or are they 2 different things? and I should definitely stick to semi ?

Hi there !

Looking for help overhere !

I am looking into buying a Yamaha MT-03, the 2016 and on version, 321cc (I am actually after the blue/black 2019 version).

While the price of a New is 5000£, I have seen quite a few deals while browsing the internet that offered bikes with 30 mileage to 100 mileage, sold at prices between 4000 and 4400.

My question would be the following : is a 600£ to 1000£ depreciation for 30 to 100 miles supposed to be for those 2019 MT-03 321cc ? Or are those...

Good Afternoon All,

I’ve recently resurrected my old trusty XT125R, due to myself and my partner being down to one car.
I’ve got it running and it’s passed an MOT, however it does need some TLC, cuddles and telling it’s pretty before it starts up.
It was stood for a long time and this is obviously the cause of the issues. It’s a single cylinder carb fuelled beast... or not.

Firstly, getting it going. It basically doesn’t want to. I have to give it a few goes and then rev it quite high...

my bike when going up the gears seems fine but when using the clutch to come back down through the gears i seem to have to let the clutch out slightly and back in again to engage the gear?! Any help on this please? I have recently done an oil change and its the correct level

Hi all.

I have a 2019 YZFR 125 with 3200 miles recorded and booked in for it's 3500 mile service. I use Esso and Shell petrol although i have used other makes when out in the sticks.

In fourth and fifth gear when accelerating with throttle rolled back to it's max and at 8200/500 revs engine stutters and wont progress. Release throttle a smidge and engine then free revs right up to the red line.

It does'nt do it in any other gear. My first thought was contaminated fuel. However its not a...

I applied my rear brake a bit hard and it bottomed out. No stopping power apart from the front so i hod a look and found this. The chain guide is not in place it i held in by a bolt at the back a a rubber bung thing at the front. so now i need to take the hose off get a new one. I am not looking forward to is beading the brakes. the brakes are the Combi Brake System so i haven't done this system before.

Not bike related but this is where the artisans live:-
My other interest is Samba drumming. Simple stuff; an aluminum shell, a skin mounted to a wooden hoop at each end, compressed by steel rims with long rods between them. My problem is that the metal rings have stretched over time and they slip off the hoops.

What I need to do is cut and shut the rings a bit tighter. I can do all of the weld prep and I've done it before, but I don't have access to welding kit any more. TIG would be favorite...

obviously it does but has anyone anyone had any experience of it causing a problem? In the UK we rairly see above 34°C , but my Honda CBR500 doesn't have a gauge (my CBR125 did :( ) so I can't see if I'm pushing a limit.

Hi guys
Could I please have some advice from you. Last month, I bought a 2017 model (2016 reg) Suzuki SV650 on 4000 miles from a dealer. This afternoon, on my way back home from work in central London, the bike died after 3 minutes of riding. It started like it was coughing and jerky and finally came to a stop. The red light on the right hand side of the dash came on.
I did let it cool down for a few minutes before restarting it which it did without any issues. However the bike died again. So I...

ive got my 50cc bike a Generic Trigger SM50 and i don't want to fully de restrict it, as it drinks enough fuel as it is. if i were to remove the restriction in the exhaust only without boring out the jets would it damage the engine??

thanks

Received my MRA screen today for the tracer, all installed fine until I come to do the edge protector...
Never noticed one of these before and it seems an absolute pain to fit. Standard screen didn’t have a protector on it so all I want to know is it really needed and if it is needed some tips how to fit the bloody thing!

Hi, considering buying a Zhongyu ZY250, but it looks to need a new Chain (and so probably a new sprocket) I can't find one specifically made for this model bit is there one that would work?

Perhaps the Yamaha 250 as this is what it it a replica of?

Any information on this bike would be appreciated.

I am aware that parts are hard to come by for these imported models, the impression I got was that when it breaks it's gone, not designed to be repaired, but cheap and not a lot of work to be...

Hi I've had the Enfield a couple of months now and it's developed a rattle from.the exhaust. I've checked all the fixings and had a look down the pipe can't see anything. It is a 64 plate and has a Cat. Could that have come loose?

I have a Kymco Miler 125 2009, its clocked in 73,000 miles and runs fine at higher speeds, but at low speeds or stopping it can cut out, unless I rev it up again, sometimes the bike will go down on the RPM screen thing, lol sorry don't know much about bikes over the basic care e.g. oil changing. but yeah the RPM meter on the dash screen of the bike goes down to like 1 then will slowly go back to 2 and not cut out and other times it will go straight to 0 and just cut out. but so far this is only...

Hi everyone!

First post on here.

I have recently changed the battery in my Lexmoto Adrenaline 125 (Yeah I know its Chinese and It's a bad choice).
The problem I'm having is when I start the bike, it slowly builds revs up until about 2.5-3k rpms then settles and idles there.

I haven't rid it after the battery change nor have I had the engine on for more than about 1 minute. Could this just be a sort of
calibration?

I appreciate all responses !

A top tip for any of you who don't like spending money . Next time you shell out on an expensive gasket for your motorbike or Harley Davidson, get some gasket paper of a similar thickness and draw round it a few times with a biro. Hey presto ! Four gaskets for the price of one ( and some gasket paper )

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...

Doing a 2000 Er5 up as a light restoration. Bike has been in the previous owners garage unused for some time. I set about removing the front wheel to remove the front forks and noticed that the spindle nut (not pinch bolt) was very loose and the wheel rotated freely. I did the job on the forks and when I fitted the front wheel back in place I couldn't put the correct torque on the spindle nut without the wheel stiffening up to the point where it was difficult to move at all. I've checked to see...

Hey I own a 2017 Yamaha NMax 125cc. This is the first bike Ive owned; I have very basic knowledge surrounding mopeds/scooters.

On my way home last night, I stopped for about 30mins to use the bike to charge my phone using the charger port the NMax provides. When I wanted to continue my journey home, the bike would no longer start.

When I attempt to start the bike I hear a loud buzzing noise and the engine does make noise as if it’s about to start but does not completely get going. Also, the...

Hi all . Ok as iv been cleaning my sons Peugeot speed fight 2 50cc air cooled . I found a small bolt at the back of the bike next to the back brake spring turns out is to top up the gear oil. Now the manual I have says that bikes after 2002 didn't need to top up the oil and done away with the bike bolt now my sons is a 57 reg so 2007/8 so it should be done away with . But anyway if there is oil.inside its 80..90. NOT HYPOID oil now what oil goes in there as I went to thunder road motorbikes and...
