Anyone care to comment on the condition of this clutch based purely on what you can see in this photo?

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 all. Can anyone help? I am trying to change the bars on my 1989 Suzuki gsx750f. I have got the bar but what size risers can I fit and do they come dedicated to particular bikes, or can I get any ones? Thanks

Recently brought my first bike a 2o12 yamaha ybr 125cc

Ive noticed if i down change through a few gears without releasing the clutch sometimes it makes the bike go completley out of gear , sometimes it may of left me in a higher gear when i release the clutch other times ill be in no gear then when i rev it makes a horrible noise then goes into gear , also noticed when it does this when im stopped , i can press the gear down lever as many times as i want and if wont stop at the top like it...

I have a suzuki Sv650S 57plate 29k

Started to notice a small rattle from the front between 2-4K revs mostly on engine breaking. I’ve also noticed when checking oil the bike ticks on the side stand from the front end. As soon as I stand it up it stops ticking.

The exhaust seems to tick abit but goes if I put my finger over it? Don’t think it’s related maybe a leak.

Should I be worried?

Oil and filter change about 300miles ago.

Bit hard to explain in words, but, I have today received an H4 Led bulb kit to fit to my existing headlamp. The bulbs are 3 sided, like a toblorone. Does anyone one know if the bulb should be fitted with the triangle pointing to the ground or the sky?

Started getting spongy and has now been flagged as slightly weak on the MOT, in fact I think it's completely gone and is just riding on the spring. I don't know if I'm searching wrong but I can't seem to find the seal kits anywhere :scratch:.

I've found a video on you tube and I've done the front suspension on my car (although it was a straight swap of the shock part rather than strip down) and wanted to give this a go :thumb:

Help needed please my stock rider turns over but just won't start any info would be great thanks

Hello all.

I'm changing bearings in my shock links. Decided while I'm there with everything out of do the swing arm bearings too. Now my 1994 swing arm has seen better days so want to replace it. Hens teeth finding one lol! The 1995 ones are easier to find and cheaper.
So..... question is, after looking on t'interwebs and finding nothing......are they the same arm?

Looks identical..... All info I can gleem says the only difference between the two years bikes was engine. Not chassis or suss...

I got a new bike, its used but in good nick.
two problems though.
1st - The speedometer is not showing the correct speed, when i was doing 38 going past one of those speed warning signs, my bike showed me i was doing 48, can i adjust or do i need a new speedometer.
2nd- When pulling off in first, the accelleation is really sluggish, then seems to kick in all of a sudden, and once ive been going ten minutes or so its fine, only happens in first, anyone know why.
thanks

Hey folks, looking for a bit of advice on what might be causing this issue.

I recently stripped and rebuilt my front (tokico) 4 pot calipers with new seals. In trying to remove the pistons (lots were stuck!) I managed to get a few teeth marks on the top edge of the piston from pulling them out with grips. I polished and Sanded the marks with wet and dry and got rid of any sharp bits that could tear the seals.

Refitted them on the bike and bled the system. The lever builds pressure (but...

Hi, pics here

Anyone know how to remove the adaptor? I need to switch out the bolt in the red circle of the firts image - the thread has gone.

Above the red circle you see the black circular button. It seems to be the only thing holding the adapton on - but I can't undo it.

Thanks

Hi I'm looking for advice on my honda cbr 125 it's runs perfectly in the dry but in the rain it will bog and die please can I have some advice one what it might be

On ebay £154 to refurbish excluding pistons if they need doing using OEM seals or do it myself?

oh I've just seen I can buy the pistons and seals from Suzuki for £78...it says kit does that mean both sides or just one? :(

Hey everyone, i bought my better half a yamaha ybr 125 (2007) but im slightly confused and hopefully you lot can help me out a bit.
Im pretty sure i need a new stator for it, but the issue is this, its a 2007 bike but is the carb model, not injection. but every time i look for stators its always pre 2007 carbs or 2007+ fuel injection. Anyone know where i can find a stator for the bike? would a pre 2007 stator be the same as what i need? dont want to fork out the money just to find i have the...

Howdy!

So, entry for knob of the day for me today.

Needed to adjust my heated grip on my throttle side and I've managed to snap the plastic element on the handle bar, the bit you'd twist to intiate the throttle.

What is this plastic part called, please?

And any short term fixes whilst I get the part??

Thanks in advance

For some reason my motorbike only shifts in to third gear when doing either 15mph or 30mph and at 30 I have to roll off the throttle to get it to shift up. It’s only third gear doing this and it has done since I owned it. 3 month.

The bike also jumps when accelerating. Only a couple times a day in my 20mile journey. It isn’t a loose chain as I recently changed my chain and sprockets as a kit. Could the symptom be a slipping clutch?

Many thanks Lewis

Put my CB500 into the garage to have the fork seals done, got the bike back and on the ride home i've noticed the steering is very stiff when I turn the handlebars to the right, but it feels fine turning them to the left.. Any ideas? Also, the seal that was leaking before is leaking again..

Hi all, new to the group. Does anyone know if a wr250 engine will fit im a 2014 wr125? I know its silly, id may aswell buy the whole 250 but id like a little project bike thats not loads of work or expensive. I would like to know if id have to put in new mounts or if it just outright will not fit. Thankyou

*Edit* yes im aware the chain is on the other side, so also are there any suggestions of good bikes for tinkering with and swapping engines etc?

2007 sv650, noticed some smoke coming out of rubber pipe attached to far left senser box on the air box, I then heard a pop and the check oil light and FI come on. Turned off engine started again and the same lights came on. Oil level fine, so checked pipe which had burst and then snapped explains the pop I guess. Currently struggling to find a relplacement pipe as I do not no the name of it. Any ideas? Hopefully a easy fix

Hello there again.

Yesterday on the way home from work the bike developed an interesting symptom of cutting out(loss of power) on my bike like you would roll off the throttle all the way back while i was cruising with 55-60 and the engine light flashed rapidly three or four times in succesion(can't tell exactly) and the power came back, i reckon the power was out for 1 second or so, it happened later on the commute again but it was for a shorter duration like a bump, again at cruising speed,...

So any ideas as to what on earth could have caused this. Yamaha Cygnus X 125

Casually riding along a nearby main road (60mph limit, I was doing closer to 50mph) when all of a sudden I felt like I was losing the back wheel and gradually lost all power. Pull bike over to the side of the road before it completely cuts out and absolutely no chance of it starting again. After waiting a few hours for the man from the RAC and then another hour or so for the recovery truck I'm back home.

When I was...

Hello guys, I’m going to be doing a coolant change on my sv650s just wondered what coolant anyone recommends?

Thanks!

Hey guys I'm new to the forum and to motorbiking. I have a rieju lc 125 pro. It keeps cutting out and currently won't start at all. I have noticed the choke cable when moved made my tickover go weird and kept cutting the bike out. Does anyone have any idea what this could be. Thanks for any help or replies

So this bike of mine is becoming more double then it's worth

When I have my lights on and use the front or rear break I loose all lights front and back including indicators had a recent problem with blowing fuse on the battery

I'm looking for somewhere to buy the diaphrams for the carbs on my zx6r g2.

Can't find them anywhere, anyone know where to look?

SO im having a major issue with my commuter bike.

came out after work this morning to find my cover off bike soaked and unable to start ... or should i say no electrics at all!!!! can anyone advise on what to try here ?

I had a quick ride out today and at one point it felt like I’d clipped a rock on the rear wheel, I was pretty sure I hadn’t so I stopped to check and everything seemed ok. Got home and had a better look and discovered the chain is ratting/slapping as shown in the video. The tension is fine sprockets and chain are ok, is it likely to be a transmission issue?

In neutral the wheel spins freely, if I put it into gear and pull the clutch the wheel has some firm resistance. I’m not sure if that’s...

I'm heading to France for a few days soon. My bike is a 2002 Suzuki Bandit 600. I'm new to riding, and the bike is new to me and I've only done a few rides so far. During those rides I've had a few mechanical glitches, though I think I've had them sorted at a local workshop.

That said, I want some breakdown cover. At least for the single trip, perhaps for the year.

Who do you recommend and how much should I expect to pay?

Looking for abit of advice 2 weeks ago I had to change the back wheel bearings as the back wheel was shaky it was fine once I changed them but today the back wheel is the same again? Could it be my bearings again? Thanks in advance.

2006 Honda xr1215 does anyone know how tight the head bolts should be

Hello, I just bought sr125 1996 with faulty starter motor and spent all evening looking for spare one all over the shop without success. There is one auction on eBay for the second hand one.
As I was searching online for the starter motor I found information that Yamaha sr125 1996 was using the same engine as Yamaha tw125 1999 and by looking on the pictures both starters looks just slidly different on the side when fixings are?
And here's my question.
Did anyone installed Yamahas tw125 starter...

How often does everyone change their oil?

Looking for a general census mine was supposedly done just before I bought it (GSX600F) but it never came with a manual and the manual I ordered has mysteriously not arrived off of Ebay.

So folks how often do you and is it an easy enough job ie do the filters get stick on like on cars? (I've had more hours fight those bloody things than I care to remember!)

I filled up last Thursday and my fuel gauge has only gone down one bar. Now it would be nice if this was a true reflection of my fuel consumption but I know its simply not true. Its a digital gauge and it was fine until the last fill up. Any ideas what could have gone wrong and how I would go about fixing it?

Thanks all.

Yo
My bike has a retro-fitted USB charging socket near the clocks/bars. I didn't fit it, the previous owner did. Currently it's hard-wired into the battery so to switch it on/off I need to open my seat and fit the fuse into the holder (or remove it).

That's a faff, and I'd probably forget it and run my battery down. So, I thought it might be better to have it switched by the ignition switch. That way, it will only be powered and charging when the ignition is on.

Is that possible? Is that easy...

Hi All,

Ignition Barrel

I'm new to this forum however I was hoping maybe someone could give me some advice on a few repairs and suggest parts as I'm really struggling to find anything online. I'm currently riding a 2012 Motor-Roma SK 125 which as far as I know is a Chinese make using mostly mostly Senke parts. however after a slide, the ignition barrel has completely snapped from away from the dashboard. Exposed underneath is just a simple notch that needs to be turned by the ignition...

Good morning people.

This morning I went to the bike to go to work, put the ignition on, pressed the button, the bike cranked over for longer than usual and fired up, being warm-ish the automatic choke wasn't on, while I was getting my gloves on the bike stalled all of the sudden. I've tried to restart the engine but the bike would just turn over but starting up after several attempts, when running the bike it coughs as seems to 'miss' some of the sparks even when using the throttle and then...

Ok..need some help, my wife has a Honda CBR 400cc NC23, the model is a gull arm not a triarm, im buying some new wheels for her birthday as she wants them powder coated but here’s the real problem, I’ve won a bid on a set of wheels and the description hasn’t said what model they are off until the guy messaged me, will the tri arm wheels fit on a gull arm model?

So was stationary at an island waiting when the car behind me suddenly shunted forward. He hadnt touched me and i responded with a hand gesture to tell him to wait as a car was on the inside/middle of the island but indicating left (and did cut across all 3 lanes to make his exit). The car behind then shunted me, my foot was on the rear break but the bike still moved forward a little as his car pushed my bike! He did pull over after i did making out it was accidental. Whats the likelihood of...

I got my bike back, from the thieving gits , but unfortunatley they have done a lot of damage.
Theyve cut all the wires going in to the speedometer unit, then smashed the unit off. i was wndering if it would be possible to fit the above speedometer on, and if it would work, the socket looks the same, so im hoping it willl just click on and work.
They also put a hole in the fuel tank, bent the foot rest up against the engine, smashid all the body panels off, and destroey all the indicators.

Hey people, still getting the zx6r sorted and aside from wheel bearings to do I have a problem with the carbs.

I took them off today and gave a clean due to running poor at low revs and also the revs dropping slowly.

So I had them off, float bowls off, pilot jets cleaned, pilot screws cleaned, main jet cleaned then back together.

When it started it ran better low down revs but the revs are still hanging.

I have sprayed carb cleaner round all the boots and vac lines and the revs don't...

Wondering if anyone can give any pointers, my sinnis kept cutting out this morning when I went to leave for work.

Idles and revs ok but as soon as you go to pull away it stalls, will get to biting point ok and any further is like trying to pull away with rear brake jammed on and just bogs down until it stalls.

Obvious points...

Don't have a side stand switch
Brakes are fine and free wheels fine

Recently did an oil and filter change on my sv, just wondering the correct way about checking the levels, do you check oil when cold or do you have to warm it up for a while then check? Noob question but not 100percent! Cheers guys

Hey folks went to ride home from work all excited to get home and as I went to take off bike cut out. It starts every time then after few seconds engine cuts out. Walked miles home then just got a taxi back to her with a torch and tools.

Noticed a hollow rubber lead dangling near rear end got no idea where it goes I'm a total rookie newbie. Any ideas ? Longest I got her running was two minutes. But obviously this lead is for something lol ??? Please help I'm sick of mechanic call outs. Bike...

Im about to start some mods/a mild rebuild on my YBR125 Fuel Injected model.. As part of this mild rebuild Im going to do a little cutting and welding to the frame. Nothing huge, Just a little welding.

Is there anything other than the battery I should remove, to prevent damage to the bike/its electrical system while welding?

I did google this but got mixed results, wondering if anybody on here has experience with welding frames and could give some advice.

Hey all,

So not posted much on here but with the sun being out I finally got round to having another go a fixing my rs125, after about 4 years of storage.

Now briefly, I had the crank rebuilt by PJME some 4-5 years ago (bare in mind bike has done ZERO miles since this) as the conrod had movement in it. I also replaced the main bearings and ALL the crank case bearings and seals. Put the it all back together and DAMN, its knocking. It was a consistant knock that happened at the same point on...

Recently I have been having issues with regard to the instrument cluster as nothing lights up other than the neutral light, now the bike does start and run as normal before anyone asks ^^

Issues already marked off the list / fixed...

1) Ignition switch was faulty so took that off and had to clean the contacts as they were corroded to hell, tested afterward and working fine.
2) Bought a new instrument cluster and tested the old one, both do work fine after testing however there is a faulty...

Hi i have a derbi senda 50. I have had it since august of last year hoping to have it fixed by September and it still has problems.A few weeks ago it was riding ok, the bike should be capable of aleast 55mph but would only get up to around 35 on flat ground and 40 downhill, i noticed milky oil so did a water pump rebuild.The bike is now back together, i went for a short ride a few days ago to test it out, it was riding fine until i got to a downhill sectioon, i rode the bike slightly...
