What more can be said about the importance of maintenance on your Harley? A staple of 2 Boss Performance is keeping bikes from the early 80s until current on the road in the best possible condition. Proper maintenance can save you lots of money down the road.

99-06 cam chain tensioners are notoriously prone to failure. If you have an interval of 25k miles since they have been checked, or worse never have had them looked at, you must! We very commonly replace these with S&S gear drives, if your crank runout is within an acceptable range or hydraulic tensioner upgrades. Plus, we carry HD replacement tires for all years, makes, and models.
