K, I ride a 426 (obviously), it is an 01. I ride it a lot. At least once a week, sometimes 3! Well my motorcycle doesnt have any compression anymore when it is cold and it is really hard to start. But once I start it and it warms up, the compression comes back and it is easy to start again. But whenever it is cold there is no compression and it is hard as hell to start. SO>>> Do I need a new top end, or just rings? >>>>> Is there something wrong with my valves? Let me know!
