Any coments on ease?

I haven't, although i do plan on doing it at some point if anyone has any tips :D

I haven't done one ofr a good few years but if you have done gearbox work before its not too difficult. A tip for the mainshaft nose bearing needle rollers is to "fix" them in place with grease during assembly. If you google search you should be able to find a PDF manual for overhauling the box, I did for the MT75.

First motion shaft is no big problem just be aware of the bearing on the inside of the mainshaft and the seal in the tube,there is a dummy shaft used to replace the rollers in the lay shaft but as said it is possible to "stick them in".
The Bullet box has these replaced with a bush for more power input.
