2005 Yamaha Big Bear 400 wheel bearings and ....?

Thanks! I have the repair manual and have been working on putting the wiring harness  back together so I can start testing for correct voltages everywhere. I did a VIN # internet search and this is what I found

Mech, that's the same thing my wife said.

Thanks for looking for me, mine ia a 2000  Big Bear 400, wiring harness is different for the 350, in fact, im having a lot of trouble finding parts for  the 2000 except OEM , when the year range its listed for generic parts the 2000 model is always omitted don't know what's different about it. See plenty for the 2000 Kodiak, which I thought would be about the same, but not Big Bear.

hey, are your electrical components installed where they go? Mine were just tucked where ever someone thought they would fit. If yours are in place can you post a pic? I also have one ground wire with no home and a white connector that plugs into no where. I'll post a pic of them tomorrow. I'm not sure where the rectifier goes or the cdi unit. When i got it they were just on top of the battery. The parts list shows them somewhere in the back, but i'm not sure where.

thanks

by the way, our vin numbers are almost the same, except my last digits are 00815

I do have everything wired back up not exactly in place because a lot of the wires including solenoid and battery fit on top of the rear fender. I will take some photos and post tomorrow

no need to post any pics. I watched a guy on youtube as he had his atv apart and i saw how everything went. I had one white connector left over and i looked at the parts drawings and it said there's a "motor control module". So, i looked that up and new it's $150. I said no way. Then i found out it'ss missing ONE word...FAN.  LOL it's the Fan Motor Controller. So, not needed right now, probably never because i don't plan on doing any heavy riding.

Other than the tube from the carb to the air box (which i'll order this week) it's just about ready. (fingers crossed) Being an after market carb, i'm sure i'll have to play around with that. 

Brainstorming is the best teacher! thanks!!!!

Glad to hear you got it fingered out. You can buy that vacuum line by the foot at the auto parts store. Measure the nipple before you go. Don't ask me how I know. It may be less expensive

just wanted to say thanks to everyone for their suggestions and support. My first atv and this forum gave me the encouragement to go ahead and fix it up. Ordered my last part needed from ebay....waiting.....amazon prime spoiled me by getting orders here in 2 or 3 days.

It looks good, glad you got it all fixed up,

starts and seems to run good, but has to warm up a bit first. It jumps when put in gear, but i've read at serveral places that a Big Bear is notorious for hard shifting and a slight jump when puit in gear. two thing i need for it is the fan motor controller, which i ordered, and eventually a pull start assembly and it's 100% done
