Re: power problem
If you weigh 240, I recommend getting an expansion pipe to increase performance, make the header long, like about 17 inches, and you will get a lot of extra low end power for going up hills. It sounds like the head needed tightening though, can you feel any air shooting out around the head when the motor is running without the clutch engaged? Just rev it a few times and see if you can feel any hot air shooting out. Air leaks at the head are a pretty common problem. Also, a fred head will give you more compression and could help you get more power too.
