I own a 2003 arctic cat pantera 550 liquid with a problem. The machine starts and idles fine but when you ride alittle and it gets hot it goes out on one cylinder and dies. You let it cold down and it starts fine again. If anyone as any ideas what the problem could be please let me know thanks toolman50

might be a plug wire or spark plug? did you try changing them?

Yes plug wires and plugs are fine also right compression on each cylinder

Well i don't know, might get better results if you post it in the general discussion forum.
