I had my rings replaced last weekend on my xb12. The did a compression check right after and it says 155/150... My question is is that good? | ||

why did you replace the rings? what was the compression before? but with out knowing what compression was before I would say 150 is good. over 100 psi and no more than 20% difference between the two clys. did you get the valves reground as well? how many miles did the engine have? | ||

That is okay, but if that was before the rings had a chance to wear-in, the compression should increase. Did they also hone the cylinder bores? | ||

I had a seaping base gasket repaired under warranty. They reringed the motor and did a comp check on it after the work was done. I was just wondering if this was ok. No they didnt re-hone the motor. I called several "known" service department and the all sid it didnt need to be re/honed. They did "recondition" the heads and cylinders.???/ Im still trying to figure that one out. So far so good though. | ||

There will be some variation for the same bike based upon locale. Current Barometric pressure including the effects of elevation will result in variations. So comparing a warm weather San Diego compression test to stormy Denver test may not be viable. Capndoug | ||

According to my buell book at least 120 and no more than 10 b/w the two..... if you cross either line, then you have probs... so right now you sound to be good to go. |
