Designed, dyno proven and made in the USA, Hot Cams performance camshafts are one of the most economical, reliable and easy to install ways to add a 5-10% power gain to your bike.
Stage 1: These cams provide better low RPM torque, pulling power, and throttle response.

Tech Notes: This cam replaces the 2047-1IN. It has better low RPM torque, pulling power, and throttle response. For best results it should be used with the #2050-1E exhaust cam. Uses stock DRZ400 valve springs.

Does your stock vacuum operated petcock not shut off when your bike is parked? Replace your stock vacuum operated petcock with this manual one. Must be shut off any time the bike is parked for more than a few hours. Fits stock or aftermarket tanks. Plastic tanks may need the hole 'ovalized' to fit the dual standpipes.
Does not fit OEM XR650L metal tank

Engine & Maintenance
Your automatic cam chain tensioner is spring loaded. This can make it difficult to install as it wants to extend before you have it bolted into place. This handy tool will back off the cam chain tensioner mechanism and hold it for you. No more awkward 3-handed contortions are required to get the tensioner installed.
