Fredette porting for a 200

I have a 2001 kdx 200 w/ fmf revpipe and fmf silencer. Can any one tell me what to expect form Jeff;'s porting as compared to stock porting considering the above mods already made? thanx!

Try asking in the KDX forum. You might receive more responses. :cool:

you will be able to wind it out a bit more for sure. mill the head and jug install a wiseco prolite and good reeds and you'll really turn lose an animal. this is the same combo I run and mine can make a KX250 work hard to pass me. gets a little pingy on pump gas though in the dead of summer (august)

I run a 50/50 mix of race gas year round anyway.

Thanks for the reply, when you said mill the "head a and jug " did fredette do the mill work? If you did the work, how much did you take off ? thanx

I had fredette do some porting on my 91 kdx 200. It seemed to enhance the motor a little bit everywhere, mostly toward the lower end of the spectrum.

My 220 has it "he's da the man!" The bike runs like a raped ape. Don't let anyone else do your porting.
