I use BikeBandit for parts but I don't think they are the cheapest out there. But with their schematics it is easy to find the exact parts you need.

I just did a quick cost on bikebandit:

$486 - Piston, ring, crank, bearings, cylinder gasket and seals.
$53 - Trans bearings and seals.
$17 - Trans washers and clips.
$388 - Trans gears.
$145 - Trans shafts.

$1089 - Total for top end, bottom end, and total transmission rebuild.

Get a bigger rear sprocket. Have the compression lowered and the porting mellowed out. A pipe and silencer for low end and QUIET! Soon the bolt on hard heads will chime in with the scary now inserts,heavier flywheels and bizarre plugs! Do not forget what that bike was made for and what you are going to do with it. From the looks of your other bikes abrupt power bursts are right up your alley!

I do not know if anyone is making plates for the bottom of the cylinder. Normally I would suggest sending it to forward motion,Eric Gorr! But maybe you have someone closer,or call Eric.
