i wonder if you should replace both set of rings. even 110 sounds quite low.
when was the last time you replaced the rings. some people say replacing rings every yr is good. but that sounds way to much bother[img]i/expressions/face-icon-small-tongue.gif[/img] if it is still working good.
what model is your machine?

Calum

 

yeah i just replaced both of them and i am running at 120... is 120 normal for a 340?

 

i`m really not sure. but that sounds more like it[img]i/expressions/face-icon-small-smile.gif[/img]
was the cylinder scored or scratched or any thing?

 

nope everything was nice and smooth, but my piston on my zr was scored and i just sent it in it get re-welded/sleeved

 

that should be good compression then[img]i/expressions/face-icon-small-smile.gif[/img]

 

Thanks for all the help guys.
