No low end power

Valve seals don't effect compression.

Yes, the miles are (presumed) low. However, it's had a lot of low use years to corrode the piston walls and rings.

#2 is gone and the others ain't far behind. You're gonna have to do some work on those holes.

 

You don't have to buy a valve spring compressor the rent the at auto zone. Get the clamp style and you will have to make a extention to compress the spring so you can get the valve keepers out. I made mine from a old spark plug socket and cut out a small part of the side to gain axcess to the keepers. I just did the valves on my bike last week and it only took a couple hours. Good Luck

 

Valve seals no, but if the valve cleanrances are off and have been off the valve seats could be scored or have carbon deposits, especially if #2 is leaking oil over the valve, this could have decreased the seal. However the rings are probably somewhat worn as well. When I pull it apart I will know for sure.
