Pop quiz everyone:

98 TDM 850.
Started & ran fine this morning.

Leaving work just now it wouldn't start. Eventually started. Ran fine 15 minutes, stopped for fuel and now won't start again.

Battery is fine. Starter spins plenty fast. Sometimes it coughs like it's gonna fire (no throttle). As soon as I give it any throttle it just turns over again. Was the same with choke. HT's seem connected ok - no tools so can't check for spark.

Anyy ideas ???

:shock:

Hey guys,
So I was riding down the A406 the other day go to kick up a gear then my bike makes a horrible shrieking noise, redlines and my clutch lever stops working. Luckily I managed to slip over onto a slip road. When I turned on the bike it made a grinding sound. Motorbike SOS came out to me and had no idea what it was. I got it recovered to home, but now the bike won't start at all. It's almost as if the battery has died? My bike is due a service but it still has oil in it, chain...

Quite recently when the weather is becoming colder, I've been noticing a lot of burnt clutch smell from slightly hard pulls from start. Ive done this plenty of times before but have only been noticing the smell very recently.

Is it because of the colder weather or could there be other potential issues?

Hi every one I’m just new here, I am seeking some advice on my 2003 Cbr600rr I have just recently serviced the bike and now coincidentally after I have done that the bike seems
To be lacking in power it’s just not taking off like it did and also the temperature seems to be rising more quickly the fan comes on when it reaches a certain temperature as normal but it just seems to be rising quicker than it did before.. so like I said I just serviced it. I changed the oil, changed the air filter...

Gilera DNA 50cc 2000 model Hi all I am trying to help a friend out with his bike
He recently bought it as a project basically all the fuel pipes and vacuum hoses were missing
I have connected them up to the best of my knowledge but still not getting fuel to the carb
Has anyone got any photos or a diagram of what pipe goes where
I have searched everywhere but cannot seem to find anything
Hope someone can help
Many thanks

Anyone know the internal diameter of the link hose from reservoir to master cylinder on a 2000 gsxr 600 rear brake please ?

Having transferred over from man-powered cycling last year I'm a little surprised that chain oil isn't a big deal. In cycling its a REALLY big deal. Anyway Ryan F9 dropped a chain lube comparison recently and made the observation that in modern O-ring chains, the lubrication is internal. The lubricant is mostly for anti corrosion. In cycling they are really concerned with dirt pickup since it makes an abrasive paste, so they want a thin coat of light oil ( not sticky). Why aren't motor cycle...

hi folks, i have just had a nightmare while on the way to the docs on my planet 125. I haven't run it for a few days and started it up as usual let it warm up for a few minutes then off i went, while rolling down the hill it died a death regardless of how much i pulled the throttle and come to a stop :(. i turned the ignition off waited a few seconds and tried starting it again and the exhaust spat (the bike would turn over but wouldnt start). i then proceeded to push it up a hill and attempt...

Hey guys just a quick question! When an engine is cold does it struggle to start? I keep my bike in my house, I use a loading ramp to get her out. And she starts just fine.

But when i finish work she's struggles quite a bit, I mean she starts but she struggles to get going. I leave her for a whilst in the morning and just after I finish work to warm up

Any advice or input is greatly appreciated. My bike is only a 125cc. Thanks again guys and gals!

:stupid:

Hi all low sided the car F3 and landed it on its left hand side, broke cast aluminium foot rest hanger so I get another but it’s bent into the swing arm, not fully but it’s definitely well out. What’s the best way to get the hanger back square? Use the 2 bolts and a plate and add heat to the frame and pull it out of heat the hanger in place and gently pry bend it straight? I don’t like the second option as I can see more broken alloy. Ideas please guys? Thanks.

Has anyone had problems with the headlight assembly coming loose , and the plastic screws working loose

Hey all,

So I have bought some bar end mirrors, thinking it’s a simple switch (which it is for anyone that doesn’t have a Z650). Now Kawasaki have used red locktite on the bar end bolts so it’s near on impossible to get them off without heat guns and impact guns which I don’t have.

Now the problem I have is that the whole bar end spins when I try to undo the bolts and if I pull hard enough the whole assembly comes out the handlebars.

I’ve read a couple bits online where people have just...

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...

Looks for opinions please… are handlebar shims safe?
Example:

The reason I am asking is on my rebel I could do with heated grips and the bars slightly closer to me. The heated grips I like are only available on 7/8th inch bars.
The clocks on the rebel are molded(?) onto the top clamp, and the rebel has stock has 1inch bars.

So I am thinking of buying 7/8th inch bars that will work well for me position wise, and using the above shims so I can still use the stock clamp.
However somewhere...

Going to attempt my first self service (well mini service) on my suzuki van van, got the bits, air filter, oil & filter, O rings but a sump washer was included i wasnt expecting (havent seen that in the youtube vids) am i right in thinking its for the nut under the bike where oil comes out? Also i was told i should have jets done... problem is im a newb and i dont know what the flip that means :/

I'm wandering what I should do next (when I have the time).

So far using this site, a Haynes manual, YouTube and Google I've learned how to;

Change oil and filters, replace clutch cable, clutch plates, unseize front break pistons, replace pads and rear break shoes, spark plug and a few other bits and bobs.

Valve clearances are next but while I've got the petrol tank off I'm replacing the rear break light switch (it's working but I believe the wires are loose or damaged as during break shoe...

Well, I COULD go to my local bike shop by they tend to make a meal of these things. Plus I didn't buy the tyre from them ( they made a mess of that last time too.) My local car place won't touch bikes. Are they all like that? I can take the wheel off myself. Where could I take it other than another bike mechanic? I didn't think it was going to be an issue!

Hi All,

I have recently got myself an MT 07 and am looking to install some protective equipment on it however these have torque settings listed. I currently don't own nor have I ever used a torque wrench and wondered if anyone knows what size would be needed for this type of job?

I have seen 1/2, 3/8, 1/4 etc. and I am a little baffled by all this seeing as I can just about work a screwdriver :lol:

This sort of thing plus occasional chain adjustment is all I will be doing so if anyone can...

I turn the motorbike on to drive home from work.
These two small lights (size of my finger tip) turn on but the big headlight nor the beam light come on. The headlight should always be on.

Ill then ride the bike for 10minutes then switch bike off and on again and the headlight works including the beam.

Any ideas what the issue is please?

Hi
Does anyone know how to remove a steering lock on a Honda CB100N I have just got the bike and there isent a key for the steering lock so I was hoping to buy a new lock and replace the old one any help is appreciated thanks.

Good morning All,

I had this issue last year and with the change in weather it has returned; the indicators on my Honda VFR800Fi are temperamental on cold mornings/evenings. The switch itself isn't sticky, but when actioned there will often be no indicator action for a minute, then the relay clicks and off they go. Sometimes I get a single click then back to nothing.

Given this only happens in the cold weather my thoughts are a sticky relay more than anything else as will be original (2001)....

Hey guys! Just a quick question how can you tell if your burning the clutch? It's just everytime when I go to a slower speed and then steadily feather the clutch just to find the biting point so I can position the bike to park it for example. I can smell something it might just be me being silly. I'm still a new rider I'm just wandering if anyone would have an idea? I just don't wanna damage my bike.

Any advice is greatly appreciated.
:tumble:

As the heading says, my question is what's the possible cause?

Hi all in need of abit of advice got a 1999 kawasaki er5 engine needs too much work for me

looking to buy a new engine but can only find half decent ones from 2004 onward models only but unsure if itll fit or not.

Any help appreciated
Cheers

What slip-on exhausts would you recommend for a Yamaha XSR 700? I don't have the cash for a full exhaust system refit but really want to open up the stock grumble a little. Nothing obnoxious but at the moment, the only person who can hear anything is the rider sitting on top of the engine.
I shouldn't need an ECU flash with a slip-on, right or wrong?

EDIT: Just seen on another post that it's not possible to use a slip-on with the xsr700 that you have to use a full system. Anyone know if...

It finally happened I dropped my bike this morning! There was no damage however the engine light came on, it wouldn't start. Then I reset the key and the engine light went off and it started, is this normal?

Any help advice would be greatly appreciated.

(Only damage was a dint on the end of the handlebars)

hi all, i have a custom chopper with 100 inch revtech motor in. the motor was purchased new in 2006 and has only done around 90 miles. yes 90 miles. i have been trying to look at some new exhausts for her as im not sure if i like the current ones or not. trouble is i cant find anything online regarding the fitment. as in what other exhausts fit. if any of you guys can shed a little light i would appreciate the help
thanks

Hello folks!!

I picked up a Pug XP6T for my boys 16th birthday and has had a problem with the rear brake not pulling any pressure to work. We've tried bleeding the system, back bleeding etc etc....
Being the model it is we are finding it very hard to find parts to replace, so am wondering if we can just put a new full rear brake system on it, or new aftermarket rear calliper it
Any other suggestions much appreciated.

Cheers
Puglife 🙃

When checking chain tension do you do it with the wheel on or off the ground, just checked mine and with the wheel off the ground it is just within tolerence by a couple of mm's, the bike naturally falls on the front wheel leaving the rear floating when on the centre stand, but checking while on the sidestand is awkward and i can't get a true result, any advice appreciated :thumb:

when my 400/4 gets hot i canot select neutral ? any ideas ( 1975 )

Hi All,

my mt09 is stalling when downshifting gears. It is very anoying the bike stalls in roundabouts when downshifting. I pull the clutch and frantically start it again whilst coasting - very unpleasant and dangerous.

Only way to avoid that is to give it plenty of revs and slip the clucth when downshifting a lot.

The smell of the clutch afterwards is not nice and pretty sure I am ruining the clutch that way.

I do have noticed stalling is more when the tank is at the end. It was not doing...

Hi , riding my 2000 aprilia rsv mille last week when something went pop and sounded like a tractor. One pipe had come off airbox and both ht leads had come off and one was destroyed.
Put pipe back and decent lead back tried restarting a few times still sounded bad and spark plug had popped out ! New plugs and ht leads ,started fine but within 30secs oil level just disappeared
Switched off bike and level hasn't come back . What's happening

I'm following along with the instructions on replacing front brake pads on the Biffer, from here

I'm at the first hurdle and think I am falling. Push Pistons Back. Push the brake caliper towards the wheel (photo here: )

Should I actually notice the caliper travel towards the wheel, cos I tried this last night and I swear it didn't budge

Hi all, I'm a newbie to this forum and am hoping you clever folks can assist me.
My elyseo constantly overheats, I have tried the usual, thermostat and the senser in the rad both appear to be ok. Could it be an air lock? if so how do I bleed the system? Thanks in anticipation.

Hi peeps.

Bit of a funny one.

Several times I have left my bike at work, when I come back to it at the end of a shift the trip meter is showing the permanent odometer mileage, and the trip mileage has been reset to 0.

Not sure if this is a fault, or if someone is somehow messing with my bike while it's parked. It is acting as it does if I disconnect the battery, but the bike has no known electrical or starting issues, battery holds charge for weeks. Got me a bit stumped.

Evening All,

Bought an R100RSthe around 7-8 months ago and dint get chance to run it until recently, although I did turn it over regularly. After some minor adjustments to the Mikini carbs (by ear!) it seemed to be running spot on despite being guilt in 1979. I did a short 30 mile ride into the Derbyshire Peaks and all was going well until I turned for home. Going downhill I got back-firing, racing engine as though the throttle was being twisted, then cutting out. Struggled home and started...

Brock talking absolutely bullsh1t and this guy explaining why...

Just been out on a ride, pulled up at a junction and bike stalled. Tried to restart her and the engine wouldn't fire up. Opens the choke and it starts up but as soon as I turn off the choke it dies. It was running perfectly up to the point it cut out any ideas. It's a 1998 Honda CBR 600 f3, 38k on the clock. Carbs were clean 409 miles ago but it was last year.
Thanks
Dave

Im new to biking and just collected my used MT from the bike shop.
I have just noticed that the steering lock will not work and on further inspection it looks like the mechanism has broken. There is a corner missing from the housing (the alloy bit) and no pin appears to lock to the stock.

I have spoken tp the shop and will be taking it back for them to look at, but my main concern is....

Even if (when) the shop repair the lock will it be ok to use. Could the stock have been damaged? It dosnt...

Hi Guys and Gals,

I have had a look at the posts pertaining to Engine Flushing and it seems that the consensus is NO don't do it!

My Bandit had a major brain fart and filled the crank case with fuel (Float valves Buggered) and yes I ran it for about 10 mins until I realised something was wrong and shut it off.

I have had the carbs off cleaned everything thoroughly and bench tested the carbs which are now OK. I emptied the Oil and dumped the filter and I'm going to get some cheap oil and a...

Hi,

I’m after some advise with regards to a no start issue I have with my CBR600RR 2004. The issue is that it turns over but the fuel pump isn’t priming, nor is the HISS light coming on for a couple seconds as it should when first turn on. Its an intermittent fault, it will work fine for a long period and then stop working again all of a sudden.

I have done some fault finding with the aid of Haynes manual wiring diagram:
Have attached the wiring diagram as may be helpful to others.

Hi ( again )

Sorry bit long.

Ive had to sign up under a new name as I cant recall my old one Very Happy

Wondering if some of you good people can give me some advice here please?

So I've got a 2009 ybr125 EFI version that I have had from new. Had been reg. serviced and looked after for a 125.

So a few months ago the odd time I would come out and go to do an electric start and the ignition light would dim. Turn it off and on again for a sec ( I work in IT ) and next time it would work fine....

OK I have a Grom that has those horrible running lights, where the front indicators stay on steady all the time unless you indicate to turn. The right side 'running light' has now stopped working but the indicator still works. I don't want to confuse car drivers any further than is necessary.

Seems like a simple fix this but I've recently bought the bike and don't have a manual. First problem is that the indicator stem doesn't have any screws that retain the lens. How do I remove the lens to...

Hello guys! I've have my cg for 2 months now it's a br/St 1996. A few days ago I've noticed a oil leak on the top cooling fin. It looked like it was coming from the rocker cover gascket so I changed it but the old one seems intact and I've been or a ride today and it's still leaking so woundering if it the cover or head that's cracked. Thoughts please.

Hi looking for some advice or any one who nos why my daelim roadwin r 2010 won't start put a replacement engine in its fireing up but won't run getting fuel spark it was runing the new engine but now it's in my bike carnt seem to get it to any idea wot it could be thanks

Hi Everyone
So been having issues with my bike for around 2 months. It is a KTM DUKE 125 (2015) with abs.
It started with the bike getting harder and harder to start, so I decided to change all the filters, fresh fuel and oil and added a new spark plug. Didn't help.
I then moved onto the ignition coil and battery. Again, didn't help. So, I investigated other things that could be causing it, replaced the regulator/rectifier, checked and cleaned all grounds on the bike. Got a voltmeter and did...

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...

Hi,

How does the HISS work on Hondas, CBR600RR 04 to be specific?

I know it an immobiliser, I’m after specifics,

There are 4 wires, what are their purpose?

Which should have voltage?

Thanks
