Hey guys, I finally got my bike jetted perfectly. It doesn't flood anymore and the spark plugs looks perfect. Just recently though I've heard this pinging noise i haven't heard before. I saw in another thread someone talking about piston being to loose?? Could my piston ring be going bad? My bikes an 2004?? Do you have to replace the rings often?? Or could it just be my gas mixture??? I'm just asking because i want to keeep the bike in good shape and i don't want something bad to happen to it. Thanks for any help you can give me!!!
