Clutch Issue?

Basicly looking for help in regards too my RS125, seems too be a clutch issue.

Basicly bike refused too go into 1st gear at stand still causing abit of an issue but I thought it was normal as such every now and again.

Went for a long ride, and no obvious problems till I came to a round about tapped down back into 1st, stopped for moment to jump on the round about.

Started letting go of the clutch lever giving the bike about 5,000rpm to jump on the roundabout abit quicker.

about 3/4 let go of the clutch started rolling forward and bang. Stalled. Massive bang came from engine? back wheel seemed to lock up as I nearly went over the handle bars!

Started bike again and tried pulling off again felt the bite and soon as I near enough let go of the lever bike stalled again.

Decided to get off the bike and push it too safety, Had clutch held in as it wouldn't go back into neutral, as I was pushing it even though the clutch was fully held in the bike would lock up? But finally got it out the way.

Gave the bike another go and no surprises it stalled again, reason I feel it is clutch related it because the bike starts perfectly well and revs fine. Still got compression not that I have a meter too check but does sound as normal as ever.

When I try changing gear the clutch makes a grating sound but the sound as now disappeared.

Also drained oil for signs of metal and none was found in oil though cyinder shaped small bits of metal were stuff to the magnetic oil out plug.

Anyone had similar issues at all? Or any suggestions will be amazing!


Other friends who ride bikes seem to think it is a case of replacing clutch plates? If so how simple?

Oh dear sounds like the clutch/ gearbox is breaking up and giving it another go will only make things worse.:shock:

the gear selector bends easy on them engines

making it hard to get in gear,,
if you say its only 1st gear try pulling away in second with plenty welly,
if its the same may be a gear box problem,
clutch plates are very easy on them to change ,
just make sure you note the way the plates come out if you not done a clutch before

Hi Jaffa

this is the continuation of an earlier post. There are 7 sets of needle rollers in this gearbox, one has obviously failed and has broken up. Hence the rollers being stuck to the plug. I agree with you No manner of clutch adjustment is going to fix this, the gearbox has fallen apart and unfortunately needs stripping down. Any metal whether on a sump plug or geabox plug is NOT normal. It never happens unless a component is rubbing/failing.

J as with the answers to you other posts you are going to have to split the cases, this is not an easy fix I'm afraid.
