Need Rebuild

[DAVE14]

MY EX loves oil now & has a ticky bit of a knock ,rockers or connecting rod bearings ? any way its time for a rebuild and Ive heard of 500 cc kits but cant find any I know about the Curtis Sparks 465 kit ,can that be stroked ?Im currently runnin 22 inch bear claws in the rear with 14 tooth front sprocket stage 2 dynojet kit k&n filter no box lid no spark arrestor etc.

I do alot of flat out speed riding stout hill climbs & agressive trail riding,I dont wanna give up any torque I need more really , but I want more top speed also .Whats the baddest kit & compression ratio I can run on pump gas?Any help would be greatly apreciated.

i'm not sure, but i believe that the 465 kit is a 440 big bore kit that has been stroked to 465. if this is true, stroking it further wouldn't be possible. my advise, if you want more top end: change your cam. a top end cam will hurt your low end torque but it is impossible to have the strongest low end AND the strongest top end pull.
