what clutch?

Post by 2strokeforever »

so my clutch went south today, had to push my bike a few miles back, is it normal for it to be working good then toast the next day???????
so i measured the disc and there 114, service limit is 112, but the plates have a lip on them where the pads? go and its 9 thou deep
i have a magura so it handles the freeplay, but when i took the flywheel cover off the magura slave was fully extended, 0 freeplay,
i know its supposed to have some, because it did when i first put the magura on
springs are 1.69" service 1.66

well anyways i dont like pushing so im gonna replace the clutch, what is the best for me, i want steel plates,
i heard barnett is good, but either there carbon, or kevlar discs were shit and wore out in a few rides

anyone tried a tusk kit, at $45 , it might be worth it just for the steel plates and springs

what about ebc?

so i want steel plates too
and dont want heavier springs, but might try them to see if it dosent bother me too much
the 450 will have less power and will be harder to start, and will be heavier, but to make up for it it will require more maintenance.

well it looks like ill be getting that if i can get it before next weekend, if not ill get the tusk and the barnett carbon plates sent on their way

how quick should a clutch die?
i was ripping along, it was muddy so it migtve been slipping a bit and i wouldnt have noticed, then i come out of a corner and ZING, so i thought i was in neutral... well i was in gear... good thing it was mostly downhill or id still be pushing

99% of all clutches die from mis-adjustment

well if it did it was partly the magura s fault, because the slave was fully extended= 0 freeplay, when i tore it down,
but i make sure it has freeplay (slave not bottomed) everytime im under the ignition cover, and thats everytime i do the airfilter, to grease the clutch arm

Barnett carbon is indestructable and worth every penny, period.

dude if the hydraulic clutch is self adjusting then how can it be my fault IF it burnt out because of improper adjustment?
and i checked it often too
i think they wore out of the self adjust range (non adjustable) and quickly went downhill from there
if i had a cable i wouldve felt the clutch tighten up and i couldve loosened it from there and got back to the truck without pushing
but ill still keep the magura
the 450 will have less power and will be harder to start, and will be heavier, but to make up for it it will require more maintenance.

I currently use OEM fibers Barnett springs and Moose steel plates, I havent had an issue yet and its been 2 years of constant abuse hillclimbing, I use the same set up in my 250.

The Magura still has the spoke nipple adjustment on the end. If that isn't set right, or manages to vibrate loose (like mine did) all bets are off. The Magura self adjustment works great, but is still not idiot proof.

When I first set up mine, I was lucky that when the clutch was disengaged ( Lever "IN"), the piston sat pretty high in the slave cylinder.

This would allow maximum travel downward ( automatic adjustment) as the clutch wore.

If the piston is allowed to bottom out in the slave cylinder, clutch slippage ( and death) will occur.

Check it out, tell us what you find.

ill make sure mine is like that, and if it isnt ill have to grind the spacer with the o ring down.... but i think ill be ok, cause the discs were wore 9 thou each, and the plates were wore down quite a bit,
i dont think ill have that problem with steel plates, and ill check it more often

Exactly....

Get your new clutch, check the lifter and push rod.... make sure everything is all bitchin', set the slave height..... and your good to go.

Lots wrong with them, main problem is the supplied springs are shit and will sag out and cause total clutch destruction.

Ill never throw money away on one again, heres my last one....

If you must use an EBC do yourself a favor and trash the springs in favor of the stockers.

If you run the Magura, that lightens the pull right there.

I run 1/2 Honda and 1/2 Barnett in my carbon clutch.... I ran a cable when I first installed it

If I we to do it now, I'd run all Barnett.

For the Ultra -Friggin'-Cheap-o Brit to fall off his wallet and throw down for the Barnett Carbon speaks volumes.

Tox had a accident recently, Chris wouldnt even take her to the hosipital... He sewed that shit together himself....

Maybe i should put up the pics of the EBC clutch I got 2 1/2 years out of with no problems and with the EBC springs- but that would be boring wouldn't it?

Same here half Honda half EBC springs. Stock cable.

Guess I'm not hard on the clutch, only use it for speed shifting on starts. :lol:
Have this EBC in here since the motor was in the steel framer. Shit like six years now! :shock:
