250r Engine Mods

[Golden Joker]

I will be buying and racing(mx) a 250r this summer, and want to be competetive.

When I buy a 250r, Ill pry have to do some mods on it to make it full race.

My question is, what is, in your opinion, the best:

A. Engine Kit(has to be 265cc)
B. Silencer
C. Pipe

Right now I am leaning towards Lrd everything.


thx,

Lrd, sparks, or ESR are your best.

If you get yourself an ESR cylinder, I highly recomend an ESR pipe to go with it, as the pipe and porting are matched to each other. Be sure to spend a few extra bucks and get the fully ported version, not the "econo" port.
