A note on those cheap China made cylinders you see. We get questions on these all the time. Here is why we don't use them. First they are often to large to fit into your engine case and case grinding or boring must be done. Second they come with a cheap low compression cast piston. Third they often have casting flaws in the deck which result in blown head gaskets. And our final thought is it is cheaply made and going inside your engine. That is not the place you want to risk it.
**A stock Raptor 660 bore size is 100mm.
**A Raptor 686cc has a bore size of 102mm.
**A Raptor 693cc has a bore size of 102.5mm (Alba exclusive)
Cylinder core: What makes a good core? Your cylinder does not have to be in good shape to be a good core. We bore 2-3mm which means as long as scoring on the cylinder walls is less than that it will clean up. If your cylinder has been destroyed and a piece is missing like when a rod breaks and goes through is then it is no good. If you are not sure send us a few pics.
