I have a 2000 yamaha blaster. I was riding it tonight in the snow and was coming across a field at close to WOT and the engine made a clicking noise and then started bogging. So i started to down shift and give it gas and it started to accelerate agian but with less power. I continued on and as I was slowing to turn around it stalled as the rpm's got lower. I tried to get it to refire but no luck. I pulled it home and checked spark which it has. It seems to have good compression when i stick my finger over the sprk plug hole. It is also getting gas. I pulled the carb and reeds off, the piston and rings look good from what i can see. The only thing that I noticed was one of the reeds is hanging open just a bit and the end of it is chipped and frayed looking. The reeds are stockers.
