by the way...no one told me the heat required would melt whatever that plastic stuff is. I might just buy a whole new assmbly

always one screw...removed 5...one is stubborn....i'm letting the PB blaster soak for a few, then try again. anyway, for some reason they were not turning the engine...maybe worn too much? They didn't look good in the picture, but, i'll replace them either way. yea, i fixed the pictures...using a macbook and still not used to it. I understand how they work, but, apparently, mine were not doing the job....at least i hope they are the problem.

ok...lol...i think i got it this time...

unfortunately, i don't have a pull starter. rope was missing when i bought it. I pulled the cover off and the starter clutch spins freely both ways. So, i ordered a flywheel puller (35mm) and when i get that off, i'll probably find those "dog" things (not sure what they're called), are all bad. I'll get it apart this weekend and let you know what i find. Another starter clutch is cheap...maybe $40 or so. If it's bad, i'll buy a new one. Again, the starter itself works great, everything inside the otor cover was just spinning freely. removed it and this is whaat i have. Those rollers do not move in or out and they don't look long enough to grab that larger gear. ugh...i tried posting photos...i hope these show up and....how in thee heck do i remove them? those screws are TIGHT!

so.....after watching numerous videos, apparently my starter clutch is bad and not allowing the starter to engage. ugh.

ok...removed the starter, tested it and it spins great. obviously it's not engaging the fly wheel for some reason. I'll have to pull those covers off to see whats going on inside there. when i mentioned the "solenoid" i meant the relay switch next to the battery. Every thing works , the starter will spin but not engage the fly wheel or what ever it's supposed to grab to turn the engine over.

So, i go to change the oil in my 2k Y 400 BB and, without reading what types of oil to use, i just put in 10w-40 motor oil.....then i decided to read exactly what type of oil i should be using. Apparently, the ATV oil is designed to also work with the clutch..lol...which is probably why i was having a few issues going into the gears, or, maybe losing 1st gear going down a hill. Ok, now that i got educated i bought like 6 quarts of the "special" oil required. Now, my second issue is it was hard to start for some reason. Usually it fires right up. So, once started i brought it up to the garage and removed the seat, thinking maybe the battery was weak from sitting. Nope...12.5 volts, but.....a mouse decided to build his nest right on top of the battery. I cleaned that all out, but, when i went to start it, the solenoid clicks and the starter just spins. UGH. One thing after another. No wires were chewed thankfully. Just kind weird the starter would do that all of a sudden when i messed with the oil. Do i need to pull the starter now and check the bendix thing? It spens real nice, it just won't engage. The wrong oil wouldn't do that...would it?

recently, a neighbor brought us coffee from....Wendy's! And i have to admit, it was smooth, and had great taste. There was nothing bitter about it.

have you looked at this site? I'm sure there's a million more, but, this is the first that came up: https://www.carcoversfactory.com/atv-covers/2000/yamaha/big-bear-400-yfm400f-4x4 or..... https://sealskincovers.com/collections/yamaha-big-bear-400/2000 or.... Amazon (of course)

so,no help on this topic?

ok...thanks again nope....they wont fit

would the plastic fenders from a 1998 grizzly 600 fit on a 2000 big bear 400?

yea, i knew what you meant...thanks again!

2000 Big Bear 4x4 400. do the front and rear drive shafts have to be lubricated? they have boots on them and i was wondering if i had to pull the boots off and grease the "U" joints? These are the ones close to the engine front and rear.
