That's a good one Alan, but I don't have CAD drawings for any of the parts I've built.
Hell, I don't even have sketches on paper for most.

Thanks

That's impressive, I have to admit, being able to machine stuff like that just on a whim.

Jimmy, did you ever run the bike with the stock carbs after the webcam and head work,etc? I'm thinking of going the same route you did, but I'm up  in the air about swapping the carbs. It would be kinda cool to compare a Dyno sheets between the two . For myself, drive ability is a concern, I'm just trying to figure out how much I want to sacrifice. Great job on your bike BTW.

FunJimmy,

How does your bike run under 3k rpm? This one tends to buck/lunge/surge up to 3k rpm and then really smooths out. I started another thread on ignition curve/weights/springs. Any thoughts?
