Hey guys sorry for the stupid question but i just want to re asure myself, i have an 01 honda 400ex with wiseco piston, titanium valves and a pro circuit T4 silencer, i recently just purchased a FMF powerbomb header and the guy from fmf said i wont have to re jet. I went full throttle,5th gear and shut it off and then i checked the plug and its still choc brown. Think im safe?
Thanks
