The length of time they last varies with several key things. They require greasing constantly to keep the dirt out. We actually take them out between every 5min qualifier and regrease.
The other thing that would blow one after a days running is that the clutch is not shimmed correct. Bad set up of the clutch will have you sticking in new thrust bearings every other run. Make sure the external shims are correct to minimise the amount of wobble on the bell.
Good tip Palmaris, I think I'll be lubbing it very often (Just a small touch of grease) until I get the right feel of it.
For the record: I don't have the clutch mod and my shimms were on the loose side... I think I'll set it up a little tighter - closer to .4mm -
I didn't have a spare and bought a mugen bearing at the track. It looks the same
