Hey Guys,
I have a 400ex with 400 overbore, 450/451 grind cam, 10.5 to 1 compression piston, full ct exhaust, k &n, jetted carb, and i have 16 tooth countershaft sprocket and a stock rear. I want more top end so what should i change the rear too.The only thing is that i don't want to loose that much acceleration so wha should i do. Plus what do u guys have done and what sprockets, and how do u like it and how does it perform?
Thanx, matt
