2000 Yamaha Big Bear lots of play in shifter


Wesley Floyd

Recommended Posts

Hey guys, Thanks for looking at my post. I haven't had a lot of experience with problems like this before, so I'm a little bit at a loss. The Quad was really hard to shift, (the dirty carb leaking gas making it idle high didn't help either). The only Idea I have would be is that the torsion spring is worn out, and that there is a normal parameter for how much it should move when those two arms of the shift shaft assembly spread apart.  That's my thought. Maybe someone who has more knowledge then me can let me know if i'm on the right track 😀

Take the shifter mechanism out of the side case and put it in the engine.  The hooked piece at the top of the shifter should grab those pins on the star shaped piece when you operate the shifter.  That star shape piece is screwed to the shift drum.

The torsion spring at the bottom of the mechanism looks fine.  They never wear out and rarely break.  When you put the shifter mechanism in the engine, there's a pin that fits between the 2 legs of the spring.

      having an issue with the unit when running under a load up a hill or in high gear, seems like the belt is slipping, there is a clapping sound coming from the primary clutch like it releases and snaps back in. i don't think I should have a noise like that. this is a friends unit and he has already replaced the primary twice with the same result.
      not sure where to look next

      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

      My king quad 700 runs rough when cold then won't start some times but not often when it's hot. And occasionally smoke's a lot when it's cold I'm guessing that's rings but I'm worried unless it's causing the other problems
       
       
       
      All help is appreciated thanks

      Has anyone else had an issue on older king quads where the oil would leak from the top of the head (due to a failed gasket) and drip onto the hot exhaust? Mine got so hot one time it caught fire. Just wondering if this is a common issue, as I've seen the same thing happen on multiple bikes that were the same model.

      My 2014 750 king quad stalls sometimes when I touch or turn the handlebars,the problem has gotten worse,my machine has 475 miles and is only trail ridden,I have a new factory battery and i have 14.2 volts when the quad is running and 13.3 on the battery when not running,also using a multimeter there is no change in volts when turning the bars until it does stall,If I pull the 40 amp power steering fuse it will not stall.......I've been told its the ECU,Hate to buy one if thats not the problem,but its kinda leaning towards that,,,,,need some opinions.
