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??

      Hey I have a 1997 big bear 350 4x4
      I replaced the shifter shaft and the shift arm linkage and the rod when I installed them all I was unaware that you had to line the dot on the shifter shaft with the gap on the linkage arm gap put it all back  together and rode it I can't get it to shift in the right gears  I can move the shift cam by hand and goes in different gears but with the shifter shaft in it riding I can't put it in R or N 
      Anyone know how to line up the shifter shaft and the shift cam s

      Hello everyone, I just picked up an 02 LT-F250F the other day and have been in the process of tearing it down to fix some stuff- one of which was the cylinder base gasket leaking like a sieve. Well, I know why that is now, and I also discovered that someone had been in there before. I didn't take pictures, but it looks like it was probably run low on oil at some point, the cam journals and the "bearings" (for lack of a better term) in the head and the valve cover are totally wiped out, very deep grooves.  From what I know it's very difficult to repair aluminum in this way, so I'm trying to figure out where to go next.
       
      1. Have someone grind down the head and valve cover and fit actual bearings in since the aluminum is screwed, and have the cam ground down to match.  I have no idea what this would cost.
      2. Buy a replacement head+cam+valve cover.
       
      #1 I was hoping someone might have some advice on, but #2 seems like it'll (probably) be the more cost effective option.  However I'm running into some difficulty, it seems like the 2001 and 2002 models specifically use a different head part number,  11100-19B10, instead of  11100-19B01 like for all earlier models.  What exactly is the difference between them? There are obviously far more of the earlier heads because it ran for over 10 years.  Are they actually interchangeable? I've also noticed there are heads from the LT250EF that has 4 valve heads but also otherwise look identical.  Would those work as well possibly?  I'd like to not have to drop $500 on machine work or new heads on a $1300 quad that I'm already putting a bunch of new parts on.  Oh, and it has a new piston and the cylinder itself looks pretty good too, as I said someone was in here before me.
       
      Any help or advice would be greatly appreciated. I'll post pics of the carnage tomorrow.

      Hello,
      I was able to repair most of the little problems on my 2006 BRUIN. I still have little things to do...
      I changed the Hazard light Switch because it was not locking when pushed and now it is not working at all. When I connect it (not sure of the wiring -4 wires but a lot of connection possible on this HELLA 3916-01 switch-) the flashing lights button (on the handlebar) is acting like the Hazard light switch.

      Soon to begin working on a 2002 (i believe) Bruin 350 i recently got back. Reportedly will shut-off while driving it, and blows a fuse (i have not gotten a battery, and begun diagnosis myself yet).
      Was told if they change fuse and it goes again for a while until it happens again.
      Figured it was worth asking here if anyone has had a similar experience, and determined the cause (worth a shot right?)? TIA.

      Hey all back again with my 1989 moto 4 250.
      After putting a new carb on it it's really sputtery, it has new gas and I'm wondering what to tune on the carb to make it idle better. I've attached a video to describe the issue more. The bike is still work in progress but I think the video gets the point across. Thanks!
