I plan on buying the crf 250l this spring (the wait is killing me but i cant wait!!) Ive been doing a fair amount of research the past few months and came across the pretty regular mod with the EJK Fuel Injection controller, FMF Q4 slip on exhaust and the megabomb header. Would be okay if i just got the FMF Q4 slip on ehaust without the other mods? I plan to once i have the money, i was just curious. Thanks!
