we have raced for 3 years and the first 2 ran the vitos kit , i highly recomend this kit , we now run a wiesco cam and a 12:1 je with a 37mm carb and alot of head portingThanks for your input. I do not think the 250 has a decomp in the head.
I think a 450 is a little much for us (a 13 and 43 tear old), we have fun running the little raptor for all it is worth. The suspension is complete (a arms, axle,shocks) so we can ride it aggresively. I dont want to go light and pull it apart later.
When you ran the Vito's kit, did you notice a change in engine sound? I assume the higher comp piston requires higher octane. I also assume the more aggressive CAM will have an effect too on sound.we have raced for 3 years and the first 2 ran the vitos kit , i highly recomend this kit , we now run a wiesco cam and a 12:1 je with a 37mm carb and alot of head porting
I can't really say, I just rode mine easy for the 1st time to break it in. If you plan on porting, multi angle valve, replacing springs etc I would buy the 263cc/11:1 kit from WiseCo and have the cylinder bored. I think the 12:1 kit from WiseCo is a 300cc big-bore kit that will require a new cylinder.The price of the vito's kit certainly makes it attractive. How much of an improvement did
it make? I may do porting and a carb later, so I would like to lay the ground work.
Would the 12:1 and Wiseco stand on its own?
