Hi All,
I did a total restoration on a 2003 Yamaha Raptor 80. Rebuilt the engine and tranny.. Started it up today and it runs great. Took it for a ride and the transmission worked perfectly. Adjusted the carb a little more and went for another ride. It ran awesome, pulled into the workshop shifted into neutral ( Neutral light came on) and shut off the bike. went to roll it and noticed she would not roll. Turned on the key and neutral light was on... After some troubleshooting I found that she is in first gear with the neutral light on and will not shift into neutral... It seems to up shift fine into 2nd and 3rd and then back down to 1st. I am hoping somebody can shed some light on what is happening... Thanks for any help...

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

Passing thought here and thought I'd pitch it to the group for debate. I'm working through a Kodiak which is basically a Big Bear in a heavier bike and the same as about anything Japanese made for 30 years as far as clutch function and design goes. This Kodiak is odd though in that the centrifugal clutch slipped a bit with good clutch material remaining and the main clutch pack seems to slip a bit as well at high RPM but also still has good clutch material left. Much like the Kawa race bikes from what I've read. Do you think it's an option to add a thin washer to the pressure bolts to put a bit more pressure on the main clutch and force it to use a bit more of the clutch material before having to replace? There's seriously like 50% of fiber left on the main clutch pack and it seems silly to replace it all before it's truly worn down.

Good morning everybody
I’ll be looking to get a cover for my Polaris sportsman touring that can be used while I take my atv to the lake for ice fishing.
min using an open flat trailer and
I want to protect it from the road salt
I know Polaris makes a nice cover but it’s kind of on the expensive side. I’ve seen some covers on amazon and eBay but was wondering if anybody has any suggestions
Thanks

Hi everyone! I have a 1986 yamaha moto4 200 that's been sitting for a while! Cleaned the carb, replaced engine oil, put fresh gas in it. Got it running and went for a ride! It was running great just a little backfire once in a while! I barely made it home on the way back and now the bike won't run at all since then! It will start if I give a little bit of throttle but dies instantly as soon as I let go off the throttle! And even if I try to rev it up it'll sound like its not getting enough gas.. it revs up a couple hundred rpm's and backfires through the carb.. it almost sounds as if I was trying to take off from zero in 5th gear! Nothing is seized though! I dissasembled the head and the piston and cylinder are fine! Rebuilt the carb, replaced the ignition source coil.. I don't know what to do anymore.. compression test shows 90 psi Specs are 128 psi but i'm not sure if I trust my compression tester.. any ideas? Thanks!!

Long story short. I bought this off my neighbor and only has 3 gears. The part that holds the shifter rod on broke, this is on the inside where the clutch is. The rod moved out of its spot and when they welded it back together only has 3 gears. I have a new case for it just need to know how to get the shifter in the right spot before I put it back together. I am missing the indicator that shows me where neutral is. A link to a good Manuel would be great. Thanks
