boilerdude Posted March 5, 2016 Posted March 5, 2016 (edited) Hi guys. have a bandit 12 problem. My clutch is starting to grab early. Just barely even disengages. So I took the (sprocket) cover off. The piston looks like it's wanting to stay out. The pushrod doesn't seem to be pushing back out of the bike like it should. The piston has even pushed that little tin guard out. There's slight chain marks on it. When I let the clutch out it locks at halfway as if something is simply bad with the hydraulics but that doesn't seem to be the case with the piston hyper extending like it is. The rod seems to be going too far and not returning. This happened somewhat suddenly in a ride. No signs of it prior. Sorry Ive never had to maintain the clutch on anything before aside from hydraulics. Anybody have an idea of what it likely needs inside there? So I can have the thing before I get started.

fatblokeonbandit Posted March 5, 2016 Posted March 5, 2016 I had one like that years ago, it ws a homd mde pushrod and 5 mm smapped off the endhow long is yours??? if ok whip the cover off and have a lok Quote
boilerdude Posted March 5, 2016 Author Posted March 5, 2016 Yea I have the cover off and rod out. Neither of the ends look out of normal. I'll go back out there in a bit and measure my rod. It's cold out right now though so the reading may not be entirely accurate. Quote
boilerdude Posted March 9, 2016 Author Posted March 9, 2016 (edited) So nothing is wrong with my rod. It is smooth and flawless. Other bikes would be envious of a rod that nice. Starting to think it's something with the master. Does the master ever tend to fail in a way that leaves pressure in the line/ does not allow return? Edited March 9, 2016 by boilerdude Quote
Captain Chaos Posted March 9, 2016 Posted March 9, 2016 usually when there's pressure in the line the clutch starts slipping. Quote
boilerdude Posted March 9, 2016 Author Posted March 9, 2016 Right... well this is starting to piss me off. May have to let the dealership sort it out. I hate investing time into something that still doesnt work afterward. Really takes the wind out of my sails. Quote

boilerdude Posted March 9, 2016 Author Posted March 9, 2016 Lets just say "hypothetically" that sometimes at a stop light I just hold the clutch in instead of engaging neutral. My idle is alittle high and I do this to avoid the first gear clunk. Whats the first thing to wear out from holding the clutch in too much? Quote
fatblokeonbandit Posted March 9, 2016 Posted March 9, 2016 (edited) your fibers would ware and clutch slip, if the piston is too far out and its only juts disengaging, then Id geuss somthing wrong with the push piece, bearing or washer the other end. 22,23,24. but ive never had one fail like that??? or the small push rod number 20.... get the cover off an d have a look see.

boilerdude Posted May 11, 2016 Author Posted May 11, 2016 Pretty sure it was the master. Failed in such a way that it wasnt allowing anything to return. I'm not entirely sure though. I ended up taking the master, sprocket cover, clutch basket, and clutch discs out of a parts bike and throwing all that stuff in. And now it works. But I think it was the master... Quote
cregnybaa Posted May 11, 2016 Posted May 11, 2016 It could be the return in the master cylinder on the handlebars, if you take the cover off and operate the clutch you should be able to see it return. there is usually a little baffle there to stop it squirting right up just pull that out of the way and operate the clutch, if it does not return all the fluid every time you pull it in it will just jack the piston on the slave out further hence the bent tin plate.

bluedog59 Posted May 11, 2016 Posted May 11, 2016 If it's not disengaging properly it could just be you have a tiny air bubble in the system or the fluid is old a u/s. Quote
boilerdude Posted May 14, 2016 Author Posted May 14, 2016 Well whatever it was. An entire new clutch system took care of it. lol. simple. Quote
