I’m just wondering what year bike i got? it seems the vin has been rubbed off i got it from a auction here in Australia engine starts but seems has a dirty carb wont idle well
and also has a problem I put it in gear and makes a grinding noise but does not move it the neutral light goes out but then when I change gear it grinds more in the higher gears as well I’m guessing the differential is stuffed so wanting to buy new part for it will start the pull down next week
this is the first bike I have worked on used to dealing with cars

Hello Folks....new to the forum. I have two Warriors (87 and 92), and an 89 Big Bear. Looking for some help with engine issues on the warrior, and my 89 Big bear backfired and died. Got spark, got gas, seems to have compression, (but haven't tested it yet...next). She rolls over good, maybe too good...seems soft. Have spark and enough compression to blow gas mist out the plug hole when cranking. Suggestions, Been running great since we got it.

I'm having a problem getting a CDI unit that works. The parts list calls for a 4XE-85540-00-00 CDI unit. The one currently on the ATV works but there seems to be a problem with the spark advance curve. It will idle fine an rev. to about 1.5K then starts bogging down sputtering, popping and basically running poorly. If you can get it above 2200 RPM it runs better. I have ordered and returned about 5 replacement modules that will not work at all. The unit currently on the bike has no part numbers or identification other than a Mitisibuchi logo. I am wondering if anyone else has experienced similar problems with replacement CDI's and if so what is the fix? So far I have not found a replacement CDI that will supply an pulse to the Ignition coil.

I have a 2001 Quadmaster. Bought it from the original Owner. Its in Excellent condition for a 2001. The guy said there was a carb problem when I bought it. It seems like it is not getting fuel. I took off the tank, cleaned it, replaced the gas with fresh Gas, Installed a New Gas Valve. Then rebuilt the carb with a Carb Kit. Started it up and same damn thing, seems like its starving for gas. It will also backfire out the exhaust while trying to accelerate. Now the weird part. I started it the other day and it ran great. We went for a ride and it ran as if nothing was wrong with it. Started it the next day and back to running crappy again. I was like WTF !!! ... Anyone have any ideas of what the problem could be?

Just got a '98 Yamaha big bear 4x4 in working condition (so far). Looking forward for some good information on this site about how to keep it alive.
