333 Performance

333 Performance Master Certified Harley Davidson repair facility, custom dyno tuning, engine builds from mild to WILD rider wants.

Shawn Lumpiesz of 333 Performance has been racing and working his performance magic on motorcycles all of his life. Starting as a kid racing and repairing dirt bikes, he soon moved on to racing and repairing metric bikes and became the certified engine builder for MI Legend Race Cars. Other certifications include Master auto mechanic, Airplane Powerplant, and Harley Davidson Master Tech. That spik

ed his interest the most and soon moved on not only to service Harleys but also to race them at local dealerships. There, he honed his skills racing a V-Rod destroyer and a Dyna superglide. After reaching the top of his field he realized he could go beyond what dealerships permitted. In 2010, he opened his business where he now has no restraints on the quality of performance work every H.D.
