Raptor 727

Would you suggest getting a 680, 686 or 690 instead then? What is the difference in power increase with the same parts; exhaust, etc...
Thx, Lewis

The best advise anyone can give you is to call ALL of the major builders and go with whoever treats you right. Currently the fastest Raptor engines are being built by Kenz Cycle Tech, Sparks Racing, Robertson, and Craycraft.

my piston is goning to be light 2 grams heavyer than a 686 piston and i was told that im not going to believe how its gonna rev
