hey guys..can you share with me about the trust bearing wear out/damage issues?i broke mine during my 1st a main,i think the advantage is the damaged still allow you to race without jamming the centax like orther brand trust bearing,just i see the lifetime bit shorter..
what do you think?
my clutch endplay 0.15-0.2,clutch gap 0.75.

Your end play is too much and should be around .1mm. More end play causes more unwanted stress on the thrust bearing as the entire end bell assembly will slam it together on engagement.
I'm actually running a .5mm air gap that has great engagement and much less wear on the shoe. I'm also running an SL3 with a 10mm spring setting. With the small air gap, the emphasis for me has been adjusting the spring setting in .1mm increments until I found the right engagement.
The manual calls for a .6mm to .7mm air gap though. When I tried increasing it above .7mm I found that the flyweights were being stressed too much and cracking around their pin holes. I even tried 1.0mm and the flyweights actually wedged in between the flywheel and the clutch disk and locked up the clutch.
Make sure you grease the thrust bearing at least every other tank too.

I went through three of them until I started to grease it every other run. Since then I've been using the same bearing (at least two gallons) without any problems.
i still worn off the trust bearing even after .1mmendplay and .65gap,frequent thick oil application after cleaning coz our surface quite trapping dirt inside.
