I am doing the first top end rebuild on a 2003 cr250. When I removed the cylinder, the dowel pins on the right side stayed in the crankcase side of the motor. They are stuck below the mating surface on the crankcase, just wondering if anyone out there has experienced this problem? Any advice would be appreciated. Also the dowel pins go around the mounting studs on the crankcase which to me seems like it will make it that much harder to remove them.

I generally don't take them out. Are you supposed to take the dowel pins or studs out if they aren't damaged?

I leave them where they sit-if its in the cylinder or case-as long as they are clean and the cylinder sits down nicely then its ok.You try to get them out and they can deform really easy.

I tend to replace them or at least grease them a bit before cylinder replacement.

I remove, clean or replace the dowels at every top end rebuild. If they are OK then I apply anti-seize and reuse.
