I recently came across this bike, have purchased an S&S motor manual for 4 in bore, and have baxter tranny info.  This is 107ci 6 speed, not sure if it's a Pitbull or a Mastiff, I believe it's a pitbull based on info I have found.  Any help is appreciated.

I typically don't send users to other forums, but the guy that runs this site is a friend of mine and I'm sure they can help you out...
