Guys I turn to you all for help before loosing my cool. First off this engine a Ebay rehab case seem to bog down when using a 14 th clutch bell, while giving full thottle. I have the engine mated to a stock ofna Pirate cone pipe, Which I think is the true cause. I listen to all input. Thanks

Are you experienced at tuning an engine? It might just be that the fuel mixture is off. Is it bogging on the top or bottom end?

This thing ROCK in the Dirt, Great Motor once it's Tuned..... You can't bet the price....
