2001 Yamaha Wolverine - Running Bad

Recommended Posts

at the end of last summer, i had re jetted the the carb on my 2001 350 wolverine...i can't remember exactly what the stock size was, maybe a 143 or so?? but i know i put a 147.5 in it...that it..stock air filter, exhaust,etc..anyway, near the end of august and september i had that baby dialed in...once it warmed up, it had great throttle response, more power, and was running like a top...i had some issues with my electric start, but that's for another thread (actually i think there is another thread on here about that problem)..so here comes winter...all winter long it ran like crap, and still is..it wont idle very long before it just stalls out...sometimes when i put it in first gear and try to pull out, it stalls...sometime i can ride it down the road a ways, and if i let off the gas or come to a stop, it stalls....it has a little backfire to it as well..not real loud, but i can hear it inside the carb..now somebody told me that jet size was too big, especially in these colder conditions....somebody told me i had bad gas (water)...thing is i filled it up and have been on that same tank all winter long, becuase i haven't riddden much, mostly due to how it has been runing...i am thinking of selling it and getting something bigger, so i want it to be running like it was last summer...so should i put the stock jet back in ??? should i drain the gas and put new gas in?? or both??

      got 7 atvs off CL recently for a good price.  one of which is a yamaha warrior.  anyone know where the vin is printed on this bike?  Haha good place to start as I do not know year or size yet.  The former owner says needs exhaust ans and clutch work.  he said it ran fine until the clutch cable broke and then I couldn't get the new cable adjusted right and it would grind gears.  things I see:  clutch cable locked up again, no brakes, carb leaking (green with algae around the bowl and has gelled gas stalagtights on it), aftermarket exhaust melted the airbox so I need something different and a new air box.  I would like the use the current exhaust if I can but I have a feeling its a redneck fix as it looks like there is an ace bandage holding it to the exhaust pipe (its an aftermarket slip-on exhaust), so I'm not sure about that- lets get the bike running first.  also, battery (looks brand new, what a shame) is dead, 0 volts.  Otherwise, bike looks to have not been wrecked, and plastics are ok (it sat outside under a 'tarp' for 3+ years since it was run last).  any tips and advise on where to start first would be awesome as this is my first clutched bike (manual).
      the clutch is my main concern- I've never rode a clutched bike so I dont even know what its supposed to feel like.  lol I'm spoiled on my automatic polaris

      So I bought a brand new carb that was set and everything. Put it all together and it runs and idles good. The downside is the bottom of the bowl is leaking fuel not a small leak either. I bought one previous and it was a cheap one and it leaked as well so I figured I'd spend the money and by an OEM one and it still leaks. Should I send it into the mechanic and have them adjust the float? I mean for a new carb I was kinda disappointed. Any help would be great! Thanks in advance.

      Has any one tried using the Harbor Freight Winch mounting plate on a 2001 Kawasaki 300 4x4 Bayou? 
    • By Mudrecon
      Now I need some settings and maybe the "what not to do for Gods sake" before I start dis-assembling. Anything guys. I see there is an idle adjust cable Is there any other settings on this carb? My drain screw appears well used

      I have a 89 yamaha big bear. Sat for a couple years. Brought it in started it up and every time I start it, it will pop and than shut off. It won't stay running. Any ideas?

      Hi:
      I am looking for some help. I just bought a 2004 Can Am 400 quad that had sat for 2-3 years. I can start it if I spray some gas into the carb but it only runs a few seconds. I haven't been able to get it to continue. Any advice on what the problem might be and how I might follow it would be very much appreciated. It had about a quart of gas in the gas tank when I got it. I siphoned that out and put in new gas. This is my first quad so I'm quite new to this.
