I need some expert advice. I'm looking at getting a 400 EX. Its got a 440 kit, 12:1 piston, cam and a DG pipe. My questions are.
Do I need to run race gas? I ran a 12:1 piston in my yz450F, and did not, but I'm not framiliar w/what the big bore honda likes.
Are there any major downfalls to running a 440 equipped EX?
Anything inparticular I need to look at w/these mods?
Thanks Todd
