I tested that today. It does the same as mentioned above in all gears. Jerky and noisy. I did take the side cover off, found some metal shavings in the oil filter housing. I'm not 100% sure how to test clutch, but I'm guessing the ol tranny is shot.

I actually just asked a few mins ago. He did say it was doing what it's doing now with him. Also, thanks for all the info @Mech! We gonna see I reckon

I know, i know...I agree 100%... I'm trying to exhaust all simple fixes before diving in deep. It's probably cuz i already know my answer lol Changed oil, re-adjusted clutch according to service manual, no luck. Soon as higher rpms come in it bucks and makes all kind of racket lol looking like I will take the transmission side cover off and see what's going on.

Yeah, I followed the instructions twist until firm then back it off. Been reading, some people say yamaha clutches are very picky on the oil used. I did use a synthetic 10w 30 ATV oil super tech brand. I may go pick up some 10w 40 valvoline SAE ATV to see if anything changes. I also read my foot brake switch could be causing the cdi to throw a Rev limit issue in there. Guess I'll piddle around and find out lol

Finished up rebuild on the carburetor, ATV starts up and runs like a dream. Now I have a new problem.... When driving under low RPMs creepin it does great. Soon as you give it some throttle the transmission kinda acts crazy. Almost like the clutch is slipping or popping out gear. 🤷♂️🤷♂️

The rear plastics are in great shape. The front has some chunks missing and bad repairs on cracks. I'm going to source a new front plastic and end up painting everything at some point.

Lil update. Haven't had much time But got the carburetor taken off and found the choke plunger was missing, that's probably my high idle issue. Anyways, decided to tear the carb apart and clean it up. Currently waiting on a rebuild kit to show up in mail so I can get started. Also need to locate a throttle cover or make one.

Good news! I found some time to get the new stator installed. The ol girl fired right up! I couldn't believe it! Although it does idle very high, Im Thinking I've got a vacuum leak somewhere. But, she's alive!!

I'd have to re-pin and terminate the plug for me to keep using the old one. I assumed it was from 2008 which is why I just went with a new one. I'll probably just try and fix it to keep on the shelf for a rainy day.

After poking around I managed to get it to turn over with the starter. I found I have a no spark issue...lovely. I printed some electrical diagrams and me and my multi meter got to work. Found I had 2 out of the 4 wires chewed off on my stator harness. Decided to order a new one and install. Tonight the new stator showed up, tore it down to get to the old one. Only had ro drill out 2 bolts to get cover off. Not bad. Gonna run to store tomorrow to grab some replacement bolts. Until then, this is where I'm at Took a picture of the old stator

Starting this build thread to keep up with everything on my build and hope to motivate someone! I picked up this 2008 Yamaha Big Bear 250 2 weeks ago. A guy that I hunt with parked it at the hunt club for a year or so before I asked him if he wanted to sell. He said " fill my feeder and throw some batteries in my cameras, and you can have it". Sounds like a deal to me! I have attached some pictures of how it sat under a tarp in the woods and when I got it home and cleaned up a little.
-
yeah, it's all there. I've been going thru the electrical diagrams and troubleshooting process. I made it to testing the stator and found I'm missing 2 wires on the 4 wire plug. Looks like something chewed em. So, I bought a new stator; should be here this week. Once that's on I'll continue down the list. I did find some more broken wires that go to the foot brake switch, I'll splice those back together also. Maybe I'll start a build thread to keep up with everything 😂😂
-
I agree. That's news to me!
-
Never knew that! I'll Keep that in mind
