Bigbore kits

(1/3) > >>

chap:
  I have been thinking about putting a 285cc bigbore kit on my 07 kx250.Has anybody on here ever done this and if so how do you like it.I have been looking on the web here,so far the only outfit i have found is max powers(rpm).Cost is about 1100 bucks american.Is there any other repuatable outfits out there,cheaper maybe or is max power it.I ride and race in the bush,i figured more power to haul my big carcaus around couldnt hurt.

eprovenzano:
I've been considering the same thing.  I've seen other places which will do a big bore, but I'm worried about reliability.  Is parts available to freshen the top end when needed?  I'm just trying to get educated.
