Good deal. You need to get really familiar with the Big Boyz Twin Cam calculator when planning an engine build. When you plug in the spec for a a 107, 110, etc and enter the specs for 79cc heads and pick a cam. .you'll see real quick why those heads won't work. Compression would be through the roof.

If you got an early bike, speed.. What works really well is barnett carbon fiber, stock plate count clutch, the 480lb Barnett spring, and an easy boy arm.. You can get all the parts from Jireh for about under 150 IIRC. I've used this clutch in my 00 116 ci dyna for about 40,000 miles.. A couple 1000 ago I had to replace the spring tho.. Motor made about 125hp/130 tq the last time is was on the dyno..
One thing to note is that you need about 6% more holding over a 6 speed bike as the primary gearing is different.. If running a 24/37 primary gearing you need about 14% more.
