Just assembled the centax. I had to remove some material as well from the mugen grey clutch, near the insides of the holes. After that it moved much more smoothly.
After assembley I noticed overall everything seemed to be somewhat thicker making me need to use less shims. I guess thats a given since its brand new disc vs used or maybe the mugen is just thicker?
Then after giving the gears a spin I hear an odd scratching noise when I point the screw down towards the ground. As well sometimes when just spinning upright.
Heres the video:
I tried a different thrust bearing, still was there. Everything is brand new otherwise. One thing I did notice is the crankshaft does not come through as far, its not enough to past the outer flange bearing. Normally it would stick out a little.
