02 Wolverine 350 4x4 Sudden loss of power
Hey Guys,
hoping someone can point me in the right direction here. was out playing around in the snow today and after about 2.5 hrs of great riding on the packed trails from the sleds, i was coming home and all of a sudden it was like the quad had a rev limiter on it. in any forward gear it's like there's a wall that the engine hits at about 1/3 throttle and then it starts stuttering and dying out. the weird thing is that in neutral it revs fine right through the power band, and in reverse it seems to work fine. I managed to nurse it home, and all the gears still work, i can shift fine (semi auto, though neutral seems a tad harder to find if i'm not rolling) and it will move under it's own power still but it's got no power. i have to crawl up hill in 1st gear because i can't rev it high enough to get to second. on the flats and downhill i can shift up all the way to 5th provided i don't have to climb anything.
any ideas while i wait for the snow to melt off it? is it possible that the parking brake rev limiter shorted out to something and is now holding me back? tranny issue? clutch?

You hit the nail on the head, it is your parking brake, seems Yamaha didn't do a very good job with them, I have seen posts all over the forum of them failing and causing the sputtering you are seeing. There should be 2 black wires coming from the left side parking brake, you should be able to follow them down to a plug, unplug it and tape it off, and you should be good.

well, discoed the parking brake switch and it seems like the problem is fixed. it was still giving me the same troubles after drying out over night in the basement (and it turns out it was doing the same thing in neutral as well as when in gear just for the record. guess i never got on it long enough to hit it when checking. weird) so i discoed it, and after a minute or so the problem went away. tooled around the yard in the new snow for 1/2 an hour and it didn't bog once. you da man wolv!

Just passing along good information, my 95 did not come with the parking brake cutout, but I can see why Yamaha did it, I, and several other people I know, have managed to take a long run with the parking brake set, a warped rotor and melted rear caliper later, I learned to check the parking brake before taking off!!!!
