Re: Board racer
Welcome to the forum. You can build a boardie without frame mods. Venice posted a nice one recently.
The true believers mod the frame and source an antique engine. One member used a Briggs & Stratton Vanguard v-twin. It looked antique after he removed the fan shroud and shaved the fins from the flywheel.
Check out the posts in the board track section before spending the cash.
