Scroll back through the posts and see the silicone job AlanH did. That with a new sensor should fix your problem. My brother went through several before he finally got one to hold up.
The first thing I would do is call yamaha and see if the recall work has been doneHi I'm Michael and have an 2003 Warrior. Pulled it out of the garage the other day to go for a spin and it sounded terrible. Appears as tho it's only firing on rear cylinders? So thought the coil may of gone bad but after checking it's ok. Now will ck the cap ends. Have already changed plugs so that's not the problem. And my little voice was saying the crank case position sensor. But then again it was also saying the coil. LOL Anyway would appreciate any good advice i could get. Thanks mm
