Sounds awsome!
But speaking from experience.......................
Send the crank out to have it balanced to your piston combo.
I REALLY REALLY regret not having mine balanced.
I've heard murmurs of some pretty out of balance +3's.
Also-save the money and run the stock '06 CDI with the green wire mod.

Also check CV-4 or Fluidyne or whatever it is.

looks pretty stout, except for the kibblewhite valves.

a very respectible builder has had bad luck with them, and after seeing his feedback and others, i wont run em..

i have ferrea valves in mine.

make plans for clutch mods also.

I have an 06 doing the Dasa big Bore and boring carb, Rage porting, Sparks pipe, stock intake tube with Pro Desgin pro flow kit and I was told I would be in 65+.. that will work for me and not even have to go in the bottum end.
