1980 Polaris TXL 340

333 cc bored to 365 cc

Stock body before Mods. We custom made an aluminum steering cross arm to fit the custom exhaust system.

We needed a custom fixture to cnc bore the mono block and head.
We also made our own copper gaskets to achieve the proper squish band.

The custom gasket with liquid copper coating before install.

And the final install of the motor.
