CT_Racing Nationl Porting

[bk7799]

Anyone out there have the CT racing national porting kit on their 250r? Is it worth the $500? I am currently rebuilding my 88 250r top end and not really sure how much $ I want to spend. I mainly ride in the Michigan woods and dunes, with a few races now and then for fun. Any information and suggestions would be appreciated.

the old style polydyne 2000 topends are the most crazily ported jugs ive ever seen... neil at c-liegh racing is right there with them. also macdizzy, though i heard from him personally that he is getting into new things. in second place i would put places like CT and eric gorr, after them i would say ESR (they have good days and bad, they dont tune each jug, just kinda port it to a base design, they make dang good pipes though)
