Hey just picked up another scrambler 850 was told the tps was bad. This atv has been beet to hell. Wiring has been tinkered with the crankcase has been replaced recently and the motor rebuilt (can see horizontal scores thru spark plug hole where it’s just been honed out and rebuilt)
my guess is it was ragged out till the motor blew a rod and rebuilt but the clown that did it couldn’t get it to run again and sold it. When I bought it it would pulse and smoke black at idle and die with throttle.
New tps installed and it won’t run period. I went to celebrate it and I’m getting 5 volts on 2 of the 3 wires running to the tps. Is this normal and if so how should I celebrate it?

Are these motors the same?
I had a quad fall in my lap a couple weeks ago. The only things I knew about it was it was a Kawasaki Bayou 220, was in pretty rough shape and was free. I couldn't say no to a fun little project. I've been looking a different ATV forums gathering quite a bit of info and decided this was the one I wanted to join.
Thanks to this forum, I found the VIN under about an inch of mud and cross referenced it to be a '98. It had been sitting outside for at least 5 years and was told it ran when parked, but had no brakes. Squirrels or mice had been chewing on the handlebar controls and it's generally just kind of beat up.
So far, I've gone through the carb (not near as bad as I expected), freed up the brakes (will probably need new cables), replaced the spark plug, air filter, petcock and put a new battery in it.
The gas tank had been empty and looked clean so I put some fresh gas in it and tried to crank it today. I got a neutral light, but the starter button did nothing. I tried pull-starting it and it wouldn't fire. I checked the plug and wasn't getting a spark. I started digging and found some potential issues and some definite problems.
I have a wiring diagram I found on here but it's just a picture or scan out of a book and hard to read. I don't see a reference to a black/yellow wire, which is my first problem.
First, it that a factory crimp? One of those wired looks like it goes to the connector in the 2nd pic. Is that just a spade lug type connector? I pulled on it with some needle nose pliers but it didn't seem to want to come off. In the 3rd pic, should there be a fourth wire?
I've read through and bookmarked the threads Andrew Baker and Arizona have going but I figured I needed to start with these obvious issues first. I have lots of pictures, so if there is something else you want to see, just ask. If I don't already have a pic, I'll take one.

wonder what meh problem is
Hello i have a linhai 300 of the 2004+- era. I had a cluch problem so we changed it. After changing it has a hard time to start going. When you pop it into gear and press the gas it barely drives but when it starts going about 20km/h it start driving well the acceleration is normal and everything do you have any idea of what could be the problem
I have a 1994 Kawi Bayou 400 which had been running well until it sat for about a month. I left the carb dry while it was park and the temp had dropped below 0C in this time. Pulled it out last night to go for a ride and it fired up just like it should but noticed when I started to head down the road I could hold it to the bar and it didn't seem to accelerate. Lower gears weren't as noticeable but 4th and 5th it just seemed to have no acceleration and half or full throttle made no difference. if I tried to go into 5th gear with any throttle it would stall. I turned around and just poked home very slow and it seemed to stay running but this was between 15 and 20 km/h max.
I have taken the carb apart and it appears to be clean and nothing stood out on inspection to have dirt or ice. Is there something I should dig more into?
I have checked the plug and it appears to be sooty with easily rubbed off carbon. I plan to get a new plug today and test.
compression with the throttle wide open is 175 psi.
I have opened the drain plug in the exhaust thinking there could be a mouse in the exhaust or something but no difference.
I do find the engine is tickity compared to my 2000 Honda but I am not sure if this is just me looking for issues or if it has always been this way.
If anyone has any insight I would appreciate it.
In the last 6 months I have done new oil and filter ( mystik synthetic)
new Peak RPM CDI
I have noticed the fan comes on more often with the new CDI, could this be a program thing?
picked up my third timberwolf 250 for my daughters. these are great light weight little quads.
have a strange one for you. the quad will NOT start in neutral. it will start in first.
if i lift up on the gear selector just enough to hear the little click (its not loud, sounds like a contact clicking, perhaps the neutral safety switch?) the light will go out, but it won't yet be in first either. that is how i have shown my daughter to start it and she can.
id like to carry out whatever repair is needed. i have the pdf of the shop manual but it doesn't really have a flow through diagram.
any help appreciated! thank you.
i need to add something. it feels like i can switch into another gear BELOW neutral.
so if i switch to neutral, i can keep pushing the gear selector, and it has another click below the neutral. the light stays on, and when i pull up into first it kind of feels like it has two positions it moves through to arrive at first.
