Do a leakdown test before you tear it apart, in case it's other than cylinder related.

Make sure there is no rust on crank where seals ride. Either get a Clymers repair manual or find the download manual. Be sure to use grease on all new seals. Lube all crank/piston, etc with2s oil. Lube trans with whatever you will run. soak clutch plates if new. If re-using clutch, give them quick lube as assembling so it isn't semi-dry.
