Bit of playing around with the IGT8 allow clutch bell with 4 bearings, crankcase cap and Buku clutch. I found out the crankcase cap eats up a fraction too much space on the crank in order to be able to tighten the clutch bell nut without squeezing the bearings. For now I removed the crankcase cap as you can see on the vid with more then enough clutch bell play to shim it back to approx 0.5 mm.
I could do with only 3 clutch bell bearings as most of the GT's are only running 2 I believe. Using the TKO black and blue seal clutch bell bearings this is an option in order to be able to use the crankcase cap.....
