So.. it a weird one.. The quad surges as you go down the road. By the looks of my tracks, it's one wheel only. High range, low range, 2 wd , 4 wd.. It just doesn't matter..
You can see in the pictures the marks it leaves. That was in a straight line, with hardly any acceleration.
Any ideas?

I have a Yamaha Big Bear 400 4x4 2000. I've posted on here about the frame being bent. Does anyone know what year frames are interchangeable? Also, would the frame from a 350 be the same as a 400? Would it matter if it was a 4x4 or 2x4?
thanks for any help with this

Is it possible to put a motor from a big bear 350 into a timberwolf? Reason I ask is that I have a timberwolf with a bit of a rod knock, and I have big bear with a bad rear end and axle with a good motor. So, is it possible?

Just bought a non-running 425 Magnum 6x6. Guy said previous owner had motor rebuilt (3 years ago or so.) It reportedly ran great but recently the electric start began failing and he put a new recoil on it which he broke immediately.
I get it home and put a new recoil on it and the pull is incredibly hard....so much so that I think I'm going to break the new recoil assembly. I also installed a new starter which won't roll it over either.
I'm thinking maybe a hydro-locked situation so I pull the plug and the motor rolls over fine with both pull start and electric start. The cylinder was dry however.
Checked the valve lash and it was right on at .0006".
Checked the compression relief spring on the end of the cam and the spring was strong and keeps the metal piece against the dowel like it should. The cam lobes look good from what I can see.
I have a small camera that I dropped into the cylinder. Could t get a pic of the entire chamber because of the angled engine but there are marks on the center piston and a couple of grooves once side of the piston top. I will include the photo.
Anyway....I'm at a total loss at this point. Not sure how to proceed and diagnose. Would sure appreciate anyone's help who might know what the heck is going on! I was able to get it to turn over about 5 times with electric start with compression tester installed which read 145 lbs. I don't know what else to do!
