I just bought a 1998 Yamaha Wolverine last week for a pretty good deal (or what I thought was). The guy I got it from said it had been sitting for a while so he changed the gas as well as the oil before I bought it. When I went to look at it, it fired right up and I took it for a short ride around his block. It seemed fine UNTIL, I loaded my quad up to go riding last Sat. I got it into my truck with no problem, but when I went to take it off the truck it was running like s%$t. It fires right up, but when you give it gas, whether in gear or in neutral, it breaks up and startss backiring out the muffler. It has absolutely no power. I replaced the spark plug with the Yamaha's NGK specified one, and cleaned out the airbox which had little to no dirt in it to begin with. Today I took the carb off, and cleaned the hell out of it. After thoroughly cleaning it I shot compressed air into the lines and nothing seemed clogged up. I also removed the exhaust and it had no obstructions. Now I'm here to ask the experts. PLEASE HELP!!!

 

Did you use the Parking break? If you did it is probably the cable. They get full of crap and will stick.

 

Do you think it would still do it if it's in neutral and not under any kind of load? I tend to think it's an engine/fuel problem.

 

Im pretty sure it would. I had the sam prob on the rappy so i got rid of the whole thing. Did you use the Parking break?

 

Yeah, I did now that I think about it. That'll be the first thing I try tomorrow. Thanks for the advice. I'll let you know how I make out.

 

No prob. If it is, you should lube the cable or better yet dont use the parking break

 

when i bought my grizzly, my dealer told me to shut the gas off whenever i transport it because the needle in the carb could get bent. i figured it was a load of crap but..........

 

Weird, I dont know how having the gas on would bend a needle. I guess strang sh$t like that can happen[img]i/expressions/face-icon-small-confused.gif[/img]

 

well the idea was that by shutting off the gas, the needle would not be able to move from the bumps on the trailer.[img]i/expressions/face-icon-small-confused.gif[/img]
