Boyesen Clutch Cover Boyesen Clutch Cover crog - Grand Rapids, MI, USA missing clutch pin bolt "This is an excellent product for my 2000 Yamaha yz125. Fits perfectly. Comes with a gasket too. Only problem is that is does not come with a clutch pin retaining bolt, which is the only reason that I had to order a new one. My original stock one got stripped out, then fell out and lost.. When you get this new one, it does not come with a new bolt and the instructions say to put in your old bolt. SHAME. I don't have the old bolt! Just include a new bolt an it would be great. Missed a weekend of racing because of it."

Engine Parts for Dirt Bikes

Staying on top of general maintenance goes a long way towards the life of your 2-stroke or 4-stroke dirt bike engine. Eventually though, engine parts break down or seize up and need replacing. MotoSport carries what you need for the simple jobs like oil changes or the major overhauls like a complete engine rebuild on your dirt bike.

Don't let a slipping clutch or blown motor ruin your planned ride day. We stock the top names in aftermarket clutches like Rekluse and Hinson or stick with OEM, if you prefer. Replace the blown motor with a piston kit from Wiseco, Vertex or Wrench Rabbit among other popular brands. Smashed radiator? We'll get you back riding in no time.

First things first, extend the life of the motor by keeping up on oil and filter changes. We've got gaskets to take care of that eventual leak, too. Find all the necessary Motocross engine parts you need at MotoSport. We'll ship it fast so you won't miss race day or that trail ride with friends. If you need help finding a specific engine part or have a question about another give us a call at 888-676-8853 or use the Live Chat.
