What is Stage of this kit? Fuel & Fire Kit for 2001-2005 Yamaha Raptor 660 SKU FF401 Fuel & Fire Kit for 2001-2005 Yamaha Raptor 660
I am rebuilding the entire engine with Hotrods crankshaft, big bore sleeve, 9:1 Wossener piston, Hotcam, kimbelwhite valves, all seals and bearings. Actual ignition is stock. Airbox is close with K&N filter, exhaust full catback with BigGun pipe. Should I use Stage 2 jet kit? Any recommendation is welcome, and I am responsible for last decision.
