motor work??

[250xrider909]

hey guys i got the 1991 250x..what kind of motor work should i do??? i have a white bros slip on with k&n filter and jet kit...Is there any big bore kits for my quad??? or should i jus put the bigger wiseco pistons in it??cams and clutches??

there are several big bore kits for these things. profab has a 295 big bore and a 350 stroker for it. powroll makes some kits for it and sparks does too. if i were you i would also put a good cam in it(WEB cams are good) along with heavy duty valve springs. to get the full capabilities from your big bore i would get a port and polish job and possibly a 3 angle valve job.

You probably want to go with a big bore kit, sum1 on here will know where to get it im not sure where. Also, get new cams, that will aid with power. Don't worry about clutches probably unless you haven't changed it in a long time. Also, maybe get a new carbureator.

depends on what you want...if you want just little stuff you can do at home...look at a small bore job, a cam, clutch kit, and all that good stuff...

If you want to spit out some money...look into GT Thunder, or Sparks racing. They will built you a stroker/bored engine with all the works for $1,000-$2,000

noo see im not looking to spend that much money on gt thunder...can someone give me other companies that do jus pistons and bigger bore

profab has the 295 kit that just comes with the piston sleeve and gaskets for aqbout $350. but u might just want to get the stock sleeve bored out some put a cam, high comp piston, valve springs and some head work. that would prolly give u about as much power as a big bore by its self would.
