Lost my clutch yesterday.

I am of the opinion that you get what you pay for, $50 seems way cheap to me. I typically use the stock fibers and Barnett steels and springs, and I don't have clutch issues. I wouldn't be afraid to use a Barnett, they've been around for a long time, I just haven't used them.

OK, got the Tusk kit today and installed them.  Going riding tomorrow, I'll let you guys know what I think for a first-day impression.  I already have to adjust my cable WAYYYY out.  The old plates were badly worn, and they had aluminums that were thin!  Tusk Kit looks good, we'll see.

Hey, that happened to me after using a synthetic motor oil. I think it coats the plates and makes it too slick, and the heat of riding gradually makes it worse. Sometimes I revert back to what is good for a four-stroke mentality and good intentions have disastorous effects!!!!

Good:
OK, the Tusk kit seems really good!  The clutch seems harder to pull, but other than that everything seems perfect.  It has really good slippage, really good disengage and REALLY good hookup.  No complaints so far.  The clutch held tight even under a full-throttle (stuck throttle!!! damaged cable) 4th gear blast with both brakes on full still digging a trench!  I'm using ATF-F and changing after every-other ride.  No complaints. :-D

Exactly... thats what a synthetic is supposed to do is help with heat, lubrication, and chemical break down...  but in a clutch it is not too good for the above stated reasons.  You run the clutch hard under load with a fully synthetic or a friction modifier additive you will inevitably have clutch slippage.  Full syn or additives are best left for the isolated oil system in a motor for cam train/piston lube.  But in a 2S the oil is only for the clutch/tranny.  Best to use a gear lube specified for clutch use of your manufacturer and model.

Been there.... Done that....    :roll:
