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.....

To be honest I'd only think about bothering with the crankcase cap in off road to keep the dust/dirt out the front bearing. It isn't really useful in on road racing and as you've found there isn't really the room to mount it anyway.

If you need the cap to get the engine stable then there is something else wrong. It might be the front bearing has an issue or whatever but as I've said before the XRDs are not the most stable of engines anyway.

Is that an aluminium end bell? If it is it won't last very long with the buku komposite shoes!
