Ok heres the problem. Last weekend while riding my brothers blaster acted up. It wont idle, and if you try to give it gas, it backfires. So i took off carb, dismantled and cleaned it, set float level to .84 which is within yamaha specs. Set air screw to 1 1/2 turns out. Reinstalled carb, I also replaced the reeds as the gap on the old ones was way out of spec. I think if memory serves right, the manual says 2 thousandths of an inch, they where at about thirty thousandths. also check compression, which is good . but it still does the samething. Almost sounds like the timing is off. SO i go to pull off the flywheel and its filled with water. Cleaned out water and checked out stator resistance which all checked out. I have yet to put it back together but if this doesnt work, what should i look for next? Im thinking maybe a bad Cdi unit? Any help is appreciated.
