Hi Steve. Welcome to the sight I'm new here too. I am the same way I've wanted a motor on a bike since I was 12 and burned out my eyes welding with no mask trying to mount a small 2 stroke to a bike (unsuccsessful) lol I Have a cr 250 and an ns 50 and just recentley baught a engine kit. 2 weeks ago I bought a grubee starfire 50 and just didnt like it so I bought a jet 80 saturday and so far I love it.. It pulls hard and gets up to speed fast mid 30's I'd say. I'm going to use my starfire to try some tweaks head milling and small stuff and see if i can play with it on another bike.. anyways I cant wait to use it next year at NH int speedway they have a roadracing series there and will use it as my pitbike let us know how you make out..
