Having a passion for the antique 4 cylinder engines, and a proven belief the old motorcycles are to be ridden regularily, is what drives the desire for building strong reliable engines.

All engine restorations are performed in house with the exception of crankshaft grinding. There is no mechanical detail of an engine overlooked. I consider each engine to be of blueprint quality before leaving the shop.

We also handle partial rebuilding including, case repair, bottom end work, rod rebuilding, cylinder repair, align boring, rebabbiting and more

The quality of parts manufacturing utilizes the finest materials applicable to the requirement. In all cases new parts far exceed the original factory specs. One favorite saying comes to mind when describing O4 parts ............. Overkill? You bet!
