I have been working on these for a long time but I recently been having trouble with the arsinal 70 kit I put on one of my bikes. I blew a head gasket and changed it out. It ran good for about 2 rides and now it will not idle and is very hard to start. I do not have a spare head but I am thinking the head is warped. Has anyone else had this problem?

Sounds like crank seals or engine case half seal. Spray some carb cleaner at these areas when it is running and see if it changes anything.

I pulled the motor from the bike and checked the head and piston. The ring was seized and caused a burn mark across the cylinder. I ordered a new one and I will install it and see if this fixes the problem.
