I have a 2006 yamaha raptor 80, that i am haveing an issue with. It has about 20 hours on it pretty new hasnt been road much it has been sitting for 3 or 4 years. The first thang is it wont start just by pushing the start button you have to push start it for some reason? And next thang is it will not stay running if you turn the choke off. You have to leave the choke on all the way or it will die, does anyone know what the problem is with this 4 wheeler? Thanks for all that can help me out here.

The reason it runs bad and won't run without the clutch is that the carb is probablu gummed up with old fuel. Drain and clean the tank, wash out all the fuel lines and the fuel petcock, replace any fuel filter if there is one. Lastly, take the carb COMPLETELY apart and clean EVERY little part and passage in that carb, if there are holes that you can't get anything through, use compressed air to blow them out. You want that thing spotless when you put it back on. Make sure the float is properly adjusted and make sure the float pin is in good shape, the tip should be soft and smooth. Check the condidion of any thing rubber, diaphragms, gaskets/o-rings and hoses. Inspect the intake boot and intake line coming from filter, check the filter itself. If everything looks to be in order, put the carb back on give it a try.

      Just picked up an 84 LT185 ATV, I understand there was an accessory add  on that gave it electric start, anyone have any info about that kit?

      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.

      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.

      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
