650cc Custom Hi Performance Built Motors.


 If you are in the quest for more power we have you covered. Below is a list of the options we offer.

Forged Pistons: High Compression (11.5:1), Standard Compression (9.5:1) and Low Compression (8.7:1). Standard Bore to .90 Over size

Custom Cam Shaft: We have 4 different versions. Mild Naturally Aspirated, Wild Naturally Aspirated, Supercharged and Turbocharged.

Porting and Polishing: From a simple port matching of the intake and exhaust ports to a full "race" port and polish.

Rotating Assembly Weight Reduction: Lightening and Knife Edging the crankshaft, and lightening of the flywheel.

Blue printing and Balancing: We make sure that each connecting rod has the same weight (+/- .25g), and that each piston has the same weight (+/- .25g)

We are constantly working to get more power out of the 650. We have a few things in the development stage (new carburetor, new intake manifold) as well as in the testing stages (supercharger). If you have any questions please feel free to call us or send us an email.
