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...
I started this project a while ago.. I have decided to make one thread I can continuously update..
So , here we go. I got this Raptor 80 in really bad condition.. Rear end frozen, Engine toast, tires dry rotted, tons of rust..etc.. They admitted they beat on it very hard.
Since they do not make these with a drive shaft anymore I decided to restore it from top to bottom..
These are photos of when I got it home.
Next up, the tear down..
First, I needed to tear it down and determine if the rear end was still good... As we all know... That is where it would be cost prohibitive to restore if it is trashed..
Got it completely stripped down and I lucked out... The rear Drum brake was caked solid inside with dried mud. That was causing the rear end to lock up. Took off the rear brakes and the rear end spun perfectly smooth.
Once I got it all stripped apart I needed to take the finish off all the parts. I am going to be powder coating the frame and many parts.. Once the finish is off each part it will need to be sandblasted to white metal .. The guy I use for powder coating gives me a hefty discount if I bring the parts to him ready to go.
You could just sand blast, but that would take a long time to get the finish off. First I used Aircraft Paint Remover.. That stuff is pretty toxic Goggles and Resperator are required. That quickly gets you down to the metal... Then you can sand blast to white metal pretty quickly...
I had another thread I had started about a problem with the tear down... It has some great info .... here is the link... It is about removing the frame bushings. ....

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????
So just as a general FYI, it might be good to check replacement parts before installing. If possible, check clearances with a micrometer before going through the trouble of assembly. I say this as I bought a new driveshaft yoke for a Kodiak because the ujoint dropped a cap and got the yoke in a bind...blowing the yoke and middle drive gear to shreds. So I replaced the middle drive gear and bought a new yoke and ujoint kit from Caltric. Caltric is usually pretty solid replacement parts. The new yoke however was a good 4mm too narrow for inside lock ujoint caps. Disappointing since it came as a kit from Caltric.
Ended up taking an angle grinder to the new yoke and thinning material off to get it to the needed 41.25mm opening size. Sucks having to disassemble everything again and start over but my fault for trusting replacement parts. Nearly 40 years of turning wrenches and I made a rookie mistake.
Well its finally happened, its time to replace the belt on my 2011 Polaris Sportsman 500 H.O. Is there anything specific i need to know before getting into it? Is there one brand of belt i should get over another? I'm still on my first Polaris and plan to keep it at least another 8 years.

Hello. I am a new member as of today. I had a quick question to ask. I recently was driving mt HONDA RANCHER 2004 GPSscape 400 and my display stopped working. I was driving the atv and all of a sudden the speedometer and the service lights went out. Also the lights stopped working. I am still able to shift gears, change from 2wd to 4wd, and can still select if I want EPS or Auto. I have checked my fuse box and have changed a few of them around. It did not change anything. I was wondering if anyone had any idea of what had happend. Thank you for your time- Trenton
So i was riding the other day and my quad randomly shut off. It started back up and ran completely fine for a little while and then it started idling terribly.
I cleaned the carb and changed all the jets and everything except the float due to the rebuild kit not coming with one and it actually runs worse then it did before.
It will run and idle decent now but when I give it gas it dies.
Does anybody know what could be wrong?
I also changed the spark plug and air filter along with the oil and oil filter.

The Hop-Up: You may be saying to yourself, “that’s a chick bike,” and you’re right. But honestly, it’s so much more than that. It’s one badass bike. http://www.quadmagazine.com/quad/features/article/0,24942,1587044,00.html

If we had a dollar for every time the question “Which is really faster, the 700 or the 450?” shows up in our inbox, mailbox, or voicemail, we’d be putting this magazine together from a bungalow on a barely inhabited tropical isle named Quadhama.
