I just put a Picco 26 in my revo. I know i should upgrade a few things, On my list is, Foc, aluminum 3 shoe clutch. I am running a THS pipe that came with the engine. What else should i be looking at? And what is a good gearing choice for it? I thought of putting a metal gear set in it but all the reading i have done there are mixed reviews. I will just get a couple extra set of plastic in case the dont hold up. Thanks for the help
