My Yamaha Big Bear shifts through all the gears good, goes into reverse smoothly, but when i go to get out of reverse it takes a lot of effort to get it back to first gear, and even then it does not go very smoothly, have to pull up on the pedal really hard, anyone else ever had this problem. Any ideas would be greatly appreciated.

You'd already know the obvious ones.. fast idle or binding between front and rear..

Does it do it if you haven't moved the bike ? Like if you just slip it in and then try to take it out again does it do it ?

Its mostly troublesome  when i pull up to hook on to my trailer i put it in reverse back up hook it up. then cant get it out of reverse, so i have to get off pull the shifter up forcefully with my hand and it will go.Its like i just cant pull it up hard enough to get it out of reverse with my feet without hurting my toes. I thought maybe i need to get some steel toed boots, but decided i really need to fix it.

I was thinking something like tyres wearing differently front to back that had caused a gradual difference between front and rear ration.. causing binding. Try slipping it in and then straight out again without moving. If it comes out then , then it is binding up. Or, try slipping it out while the bikes moving, and in particular try blipping the throttle just as you go to slip it out so the load comes off the gear. Also perhaps try driving straight backwards without turning and then again turning the steering to see if that makes a difference.. If any of those things makes a difference then it's probably a binding up between front and rear putting a load on the gears.

Other than that, some part of the linkage going over center ? So it has good leverage pushing into gear but then goes too far so the lever is at a steep angle.. But that may not be an option in the case of a yammy..

mine does that sometimes. i just kinda rock it a little and get it back in neutral.

but....it also will go into reverse by itself if i accidentally push past neutral into reverse mode, so maybe it's not going out of reverse?  I'm thinking i need to adjust the cable tension looser. (?)

It doesn't take much to cause what Mga is describing.. needing to rock the bike to get it out of gear. Having new tyres one end and half worn on the other end can do it, even having unevenly/incorrectly inflated tyres can do it.

I've "fixed" people's 4x4 trucks that were "stuck in four wheel drive", by blipping the throttle in gear just before I slipped them out of gear.

So yours will just go in reverse without turning the switch. I always turn my reverse knob switch but have never tried it without turning it so it may not be doing anything either. Last time i rode it i had trouble with the neutral light not coming on, maybe im just not getting it to neutral, but it will roll like its in neutral, neutral has always been hard to find, pull up too hard and it goes to 1st just pull up gently to find neutral,. I think whatever is happeninng might be related.

no...i have to turn the switch for reverse.  just sometimes if i push it into that position, it's still in reverse (light on) i replaced the foot pedal with an arm, so i just go back and forth and it comes out of reverse. doesn't happen all the time...just once in a while. maybe it needs more spring pressure to release the reverse cable.?  I'm going to play around with it this weekend. ( the foot linkage had a lot of wear/play in it, making it hard to find gears, so i went with the side shifter instead of replacing the foot linkage...my cheap way out lol )

right now, i've been using it to drag logs out of the woods that i cut a couple of years ago. gotta say, that thing has the power to pull them out and some were big logs.

That sounds exactly what mine is doing I remember your post about the hand shifter thought it was a good idea because of this problem.

also, after replacing the boots and lower ball joint, i backed the clutch off a little....that seemed to help. My theory (probably wrong) was that my clutch was still engaging making it hard to get out of that damn reverse...so, i loosened the nut and turned it CC. I might do a little more after i ride it.

      2000 Yamaha Breeze 125 slips in Forwards, runs fine in reverse
      By hengstserepair
      Howdy ya'll. I am working ona 2000 Yamaha Breeze 125. It was in rought shape when I received it and I am working through issues as they pop up. The quad had been sitting for years. I was able to get her running again, but I need your help with the following issue:
      I don't trust the transmission yet and I don't want to make problems any worse. So, I haven't pushed things hard at all. Low rpms, less than 5mph in reverse.

      Nuetral: Runs as expected
      Reverse: She seems to be driving fine at slow speeds. Going into reverse at idle is fine, coming out of reverse back into neutral won't work (the shifter is just stuck). As soon as I turn off the quad, I am able to shift around without any issue.
      Forward: It slips. It seems to only transfer power to the wheels on a smooth surface and going slightly downhill. When shifting into forward at idle, there is a clacking sounds during the transition. Shifting back to nuetral works just fine.

      Other Notable Symptoms: There was old oil in the vbelt and when I was tuning the carb, it starting blowing out of the CVT cooling vent at the front of the quad. Made quite a mess. There is positive crankcase pressure due to piston blowby, that I have not decided whether or not I am going to fix (customer budget dependant).  Since the oil was old, much darker than the new oil that is in the crankcase, I am thinking it seeped past a bad seal while it was sitting for years. The oil that was in it when I first got it had gas in it.

      Thoughts: I am thinking maybe there is an issue with the clutch. I worry about the old oil intermingling with the dry centrifugal clutch. I was thinking my next step would be to take the cover off of the clutch and inspect it.

      Let me know what you all think. Any advice and ideas is greatly appreciated. This is only the 3rd quad I have worked on and I have a lot to learn.

      2000 Yamaha big bear 400 won’t start
      By Mister907
      Hi guys, I have a 2004 big bear 400. Last winter while plowing the driveway, I heard a loud pop from the left side of the engine. It continued to run as I looked for leaky fluid, but then died shortly after backing it up and won’t start now. The oil light comes on when I try to start it, no noise or anything else. 
      No blown fuses that I can find.

      2007 Yamaha Big Bear IRS Short
      By jeffinotown
      Hey guys and gals. I've been working on my friends 2007 big bear IRS. Unfortunately after 3 different people got their hands on it and only made things worse every time.  After months of finding just crazy problems everywhere. I'm finally at the point we're its almost 100% !!! But I'm getting a short somewhere between the 4xW switch I believe. I managed to by searching the internet like a  fiend, got my hands on an official Yamaha wire harness for the year and make. But I don't have the numbered component list and to be honest. After hours of going through and making everything so it's  easy to reference. If anyone has a picture of the referenced components. I would be forever in your debt. I've spent hours marking up the blown up diagram so it will be easy, for any possible future repairs. Please and thank you. Here's a picture of what i have so far.  Unsealed it in plastic so oil and crap won't spill or get smudged. This damn things worth it's weight in gold.              Thanks Jeff                2007 Yamaha big bear 400 IRS.       YFM40FBW

      Starter circuit cut out relay 1997 Yamaha Big Bear 350 4x4
      By crankin
      I have a 1997 Yamaha Big Bear 350 4x4. It used to start right up. Then all of a sudden it wouldn't crank. I have a schematic for it so I started tracing the problem. I had no power at the starter solenoid. According to the schematic the power comes from the neutral switch and through the starter circuit cut out relay. I cannot locate the cut out relay on this machine.. If I apply power to the relay it will crank with the start button.
      The neutral switch is hard to get to with all the brackets on this thing. I did find out from all my research that if I apply the rear brake lever it will start.
      Does anybody know if the cut out relay exists and where it might be found?
