I just bought this bike and the guy said the engine was pretty fresh and all that was done to it was it has the Athena 476 kit on it, so he said anyways lol. Anyways if you let the quad idle or you lets say put around on it with the throttle not much off idle when you get ont he gas it will puff some blue smoke. Nothing major its not constantly smoking if your riding it but wondering if this would be the piston and rings wearing or maybe valve guide seals???
Also it runs like a bat out of hell with no dead spot the throttle is instant but if you just barely cruising on it the engine feels like its under a load the you rev it to alil past 1/4 throttle and frees up like it should. Maybe jetting off . Any help would be good thanks Mark
