ok guys my blaster seems to be getting a little low on compression. it has about 55 hours of HARD riding on my KOR top end. it is completely leak free. and jetted a tad rich. doesn't 55 hours seem a little short of a life? im thinking it just needs some new rings but not sure? how long have you guys ran with the same set of rings? i do have a compression tester but its an junky ebay tester and its so far off its not even funny.
 
It really comes down to a few variables. Type of riding, airfilter always clean, rpm range you ride in, oil you use etc etc... I usually re ring mine around 40-50 or once a year and i also change wrist pin and bearing if not just the bearing, and also the circlips.
 
fast aggressive trail riding, always keep my uni air fiter clean, i run a trinity pipe so im almost always in the upper part of the rpm range:), maxima super m. do you think it would be a good idea just to put in a new piston while im in there or just rings, wrist pin, bearing and circlips?
