    How do you know it lost compression? Did you do a compression check? Are ya sure it didn't lose spark and you are mistaking it for loss of compression? Clarify your problem and I can help ya. I need more info.

Remove the push rod tubee on the front jug.see if the pushrods are moving up and down.see if they are loose.if loose adjust try again.
your valves may be stuck open if not stuck open pour 1 once of mystery oil in head try comp test again.[this is to check the rings}if still no comp you have a hole in your piston or blown head gasket

What is the Compression for a 1985 Harley Davidson 1000 cc sportster?


Are you asking what a compression reading should be or the compression ratio? If you are troubleshooting then you should use a cylinder leak down tester. It tells you alot more about the engine.

1982 harley davidson sportster XLH . Lost compression while riding . and it died. have electric but will not turn over or start. pistons not moving. gears work but there is not much resistance. . where do...


You need to tear the motor down, sounds as if the pistons seized or you broke a connecting rod, or bearings went out.

In any case you need to have someone that knows what they are doing check it out for you.

Could be a head gasket, hole in the piston, a broken ring, a piece of carbon under a valve, or even a broken valve. Could also be a push rod. Any more details?
