[QUOTE="dkgoodrich, post: 1327664, member: 80065"] I spent 750 on the bottom and top end [new sleeve] 33 hr ago... why would the cylinder be out of round? It still has great compression and starts 1st kick. I plan'd on re ringing it, new reeds, jetting it and running it for another 15-20hr then replacing the piston and rings. I have heard soo many mixed opinions on how many hrs it should get.. I've even heard lifespans as short as 5hr a ring and 15hr a piston, all the way up to 35-40hr a ring, 60-80hr a piston. Most people I have ran into giving me advise about how many hrs it should get simply guess by the 'tanks of gas' ran though it and have never actually ran a hr meter on there bike. I edited the orig post with needle settings and slide settings that are in the bike and whats in my manual.. Everything is so far off what my manual says that I fell like I might as well start with a unmolested carb or find someone else to verify what should be in it. I always thought it ran good till I bought a couple other bikes and rode them, specifically our ktm 125.. Also I have read every jetting link on this site, just before I got started wanted to see what it had in it and start with all stock stuff, now I'm a little confused and am curious why someone would have changed all this stuff so drastically. Thanks for your time, dk [/QUOTE]
