I'm thinking about getting this kit?

I've been wanting to build my honda trx70 beginners sport quad for racing for awhile now. I want to get the 110 kit for it, but i'm not sure if the transmission is going to handle that. And if the 110 kit will burn it up, is the 88 kit worth the money for the small amount of power increase?

BTW it is a 4 stroke engine, 100% stock right now

One way to find out. Build it up and see. My hypothesis is you'd kill the clutch on it before anything else.
Edit; if it's a one year only, may not be a good idea to take it that far. Waste of money to do all that work and not get parts, but if you can get motor parts gotta be other parts somewhere?
