clunky gear changes and what seems to be a tapping sound


Recommended Posts

when i change gear there is a clunk both up and down and on every gear? i've been told this could be the clutch or the chain needs tightening.

Depends mate, need a bit more info, what bike, where is the sound coming from, does it happen neutral into first, whats the oil level like??

Posted

its only a ybr125.


oil level is fine (think ill double check later) was only changed about 500 miles ago so should be ok


erm not sure on neurtal into first but i think it does will check later (at work atm)


sound is coming from below me, thought it was gearbox at first but been reading around and they said its chain. just after opinions, i've never done any mechanical work at all so i'll prolly book it in at dealers for them to look at it.

It should tell you how to tighten the chain in the owner's handbook - or ask Houdini, he can do it while still riding, he's had that much practice :lol:


If you tighten the chain and the clunk is still there it was something else - process of elimination, but that's a free and good place to start the investigations.


A dealer will be happy to charge you for an hour's labour for a 15 min job that can be done with the bike's own tool kit.

yeah, its just if it isnt the chain and i have to go to the dealers i wont be able go in until next week and so could cause damage. ill have a look tonight and hope if it isnt the chain that i can get it in for saturday

Difficult to say but chain would be first port of call, could also be that the clutch is not fully disengaged so check you have the clutch leaver all the way in.


How far do you have to let the clutch out before it bites, it could be that you need to adjust it (easy to do with the adjuster at the end of the clutch leaver)


Or it just could be a clunky gearbox!!!!

does it take long? i'll only have an hour tonight because of going to my 2nd job. do you think ill have time to do it? or will it be ok until 2moro night (another 70 miles 2moro)


also i think the noise is there when i drop the revs low to slow down.

Posted

it bites the same as when i had, about half way (maybe a little less it seems to bite)

simple things first mate, adjusting chain is a 30 min job. adjusting clutch out a little is 5 min job, try both of those and see if it sorts it.


I am 90% sure that if you do both of these things then it will solve the problem. Clutch should only have a couple of mm free play before it starts to pull, and it should bite about 3/4 of the way out.

thanks guys. ill try tonight (or 2moro night because of time tonight) and hopefully sort it out.
