1987 YFM350FWTB 350 4x4 Big Bear when going uphill will sometimes act like the clutch realeases then re-engauge all at once.
Seems to maybe be little more often if the engine is at about 1/2 throttle instead of at lower rpms.
I have the Factory Service manual and checked the external clutch adjustment screw as ok and the H/L/reverse shifter lever linkage as adjusted correctly. It appears to be maybe a internal (inside the case) clutch issue or ??
This is the type Big Bear that has the manual shift lever on the left front fender and has the manual foot shifter lever with 5 speeds forward.
Can someone tell me how the primary and secondary clutch operates?
I assume one is mechanical and one is centrifugal. (what I'm asking is one clutch for the higher rpms and one for the lower rpms or ???. (the clutch appears to only momentarily release at the higher rpms is why I ask. The cycle has about 3000 miles of low speed through the brush hunting and has been well maintained, oil changed, etc and no deep water or mud useage.
Anyone been into a similar issue with the big Bear ATV????
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

I have a 2005 Sportsman 500, Instrument cluster will not illuminate, hi/lo beams work though. Any tips or troubleshooting info is greatly appreciated!

Does anybody know where I can buy a complete wiring harness for a Yamaha bear tracker. If not could someone send me a picture of the the colors of the wires coming out of the cdi plug and voltage rectifier. So I can get an idea of how I need to wire it. Also where can I find a wiring diagram for them?

I have a 99 Kodiak 400 4X4 that I picked up for $300. The previous owner had modified the foot shifter by welding a piece of rebar to it so he could hand shift while plowing. As you can imagine, the allows for much more torque on the shifter than it was designed to have, and he broke the stopper off of the the shift mechanism. No big deal, I ordered the part and put it back together, went through the carburetor and off we go, it runs pretty good.
The first thing I noticed is that when I put the shifter all the way down it goes into reverse, I'm supposed to twist a knob to get it to reverse but this seems to be disabled. Also, once in reverse, it's a bugger to get back out. I have to hold the shifter up, then quickly back down and up again to get it to come out. All forward gears work fine, clutch is tight, no problems.
The reverse cable and lever are in tact and seem to move freely.
My question is this: What does one normally have to do to get this thing into reverse? I assume put it in neutral, twist the knob, kick the shifter down. Does the brake need to be applied? I'm not sure what's going on here, I suspect it's been 'modified' as it goes into reverse without the proper precautions, just not sure if the mods were external on internal.
