Hi everyone, new to this site. I’m looking for some help with my 2002 Yamaha Blaster. It’s hard to explain what’s happening. For starters, it’s has little to no compression, I can push down the kicker with 2 fingers, but I few days ago it word start after 2-3 kicks now it’s taking closer to 30 for it to kick over and only stay running for a few seconds, then I’d have to push start it and it would run. When running it was running fine through 1,2, and 3rd gear but once it gets to 4th gear I can only go about half throttle, if I go more it bogs out and wants to die. When given full throttle it sounds like it’s spitting or backfiring. It has a new spark plug and a new air filter. Any ideas of what this could be?
