HOTCAMS Camshaft - Stage 1 HOTCAMS Camshaft - Stage 1 Dylan - Great performance upgrade "I got this cam for my 2002 Honda xr100. It increased the top end performance ALOT. I ended up needing to rejet it and put a 105 main from a stock 100 main and it's a bit to big, so a 102 would be good. I also ended up gearing it up, from a 50 tooth rear to a 46 rear, It rips now. This is a awesome performance upgrade for the xr/crf 100! And a good bang for the buck."

Is your clutch slipping or dragging?

A Motorcycle clutch takes a heck of a lot of abuse. A few millimeters of friction material and a few steel plates is all that holds all the power of your bike, transferring it to your gear stack and ultimately to your rear wheel. If they become worn or, worst case scenario, the friction pads separate, you'll need a new clutch. Generally, a new clutch will last a long time even on track-only bikes, due to new materials being introduced like kevlar and carbon fiber. The EBC Street Racer clutch kit is one of those, impregnating their friction pads with kevlar for higher friction, longer life and better heat resistance. If you need a full kit that includes the drive plates (the flat steel plates that don't have friction material) as well as uprated springs, have a look at the Barnett Clutch Kit.

While you're at it, why not replace your clutch & stator covers with stronger, lighter and better looking aftermarket ones? Woodcraft makes replacement covers for just about anything that feature built in replaceable slider pucks to protect your engine in a crash. Just want something that looks trick?
