Is 110 PSI compression ok?

[B-rent]

Well I feel better now about the coils and ignition that i bought for it. I had a guy back into my bike and tip it over about 2 weeks ago. He payed me cash and I felt that before I dump the money back into it I should check the compression to see how things are. I feel better after hearing all your comments.

Oh crap, that really wasn't what we meant.

What we really meant was the thing is a pile of junk, but no worries, I'll take it off your hands for $50 plus shipping

I put some oil in the cylinder for the second reading and found that the pressure went well over 150 PSI in all cylinders

Define "some" oil. Should be about one tsp, just enough to help seal the rings. If you put too much in you're shrinking your combustion chamber and that will make your readings go up artificially (i.e., past what you'd get with a ring replacement). Service limit on the 70s 550s was 90 psi IIRC, and 100 after 79.

I didn't measure the amount of oil, I figured more was better than not enough. When i cranked it over I had oil shooing out of the cylinders. I guess I had enough oil in one cylinder for all four.

It doesn't burn any oil that I can see, and I never have to add oil between oil changes. I really want to tear into it, but I want to make sure I have a good reason to before I screw something up. I probably won't be doing this for a while. I've been looking for a parts bike to screw around with but they are hard to find around here in Idaho (I check craigslist at least a couple time per week) and it seems people want money for them too, crazy. When I bought this bike I knew nothing about it and thought I would be lucky to get one season out of it before it died. I was very wrong about that.

This gals' got a couple. It's MT, not ID. Close enough?
