recently picked up some project bikes off CL for cheap. got a honda fourtrax (the ancient 4x4 kind with the straight axle in the front as well as the rear and a back-up kick-start) plastics are crap, but my goal is to get running like a champ and patch the plastics up and sell to one of my many friends that want a reliable 4x4 for dirt cheap and doesnt care what it looks like.
so the former owner says it needs carb rebuilt, but its sat for 3+ years since so who knows. things I see: carb is missing (he gave me a box of parts along with the bike), engine turns over and feels good with kick-start, brakes need work, battery missing (That always puts me off, cause then I know most likely someone's been tampering with the electrical.
I thought I would make a quick "How-to" on setting wheel alignment since I was flipping my tie rod ends and I was going to have to re-align the wheels anyways.
Here's some of the tools you will need...
1.) Start with the ATV on a smooth and level surface, like a cement garage floor or driveway.
2.)Center up (Eyeball It) the handle bars and lock them into place with 2 ratchet straps, one on each side of handle bars. This of course prevents them from moving when your adjusting the tie-rods.
3.) Place two Jack Stands approximately 2 feet in front of the atv even with the outside edge of the two front wheels.
4.) Wrap a length of string all the way around the ATV and Jack Stands, Start and end at the rear hitch. Make sure the string is the same height from the ground on all 4 wheels. I like to attach a few elastic bands to both ends of the string before attaching the string to the hitch. This makes it easier to adjust the strings when moving the Jack Stands.
4.) Break lose the inner and outer tie-rod nuts. NOTE! Make sure you use 2 wrenches, one on the nut and one on the ball joint. Damage can occur by only using one wrench.
5.) Adjust the string by moving the Jack Stands in or out untill the string just touches both of the side surfaces of the rear tires on each side of the ATV. This will take some time to get it right but it needs to be done!
Check manufacturers wheel alignment specifications on your specific make and model before you adjust any components.
For this wheel alignment I'm using the Polaris Specs which seems to be a common setting.
Polaris - The recommended toe alignment is 1/8″ to 1/4″ toe out. This is a total amount, not per wheel.
6.) On the front rim, measure the distance from the string to the rim at the front and rear edges of the rim. The rear measurement should be 1/16″ - 1/8″ (.2 to .3 cm) more than the front measurement.
7.) If an adjustment is necessary, Turn the tie rod itself with a wrench or your hand in small increments. It doesn't take much to move the tire a long way, so go slow. Keep re-checking your measurement's until you have a 1/16″ - 1/8″ differance to the string.
6.) Once your satisfied that you have the correct "Toe Out" measurements you can tighten up the inner and outter tie-rod nuts on both sides. AGAIN...make sure to use 2 wrenches.
7.) Now take your ATV for a test drive to test your adjustments. If it still pulls one way or the other, just repeat the above steps to tweek the adjustments again utill your happy.
The whole process only takes about 15-20 min.

I posted earlier looking for a wiring diagram, but maybe someone can help me with the problem if they’ve had it before.
The quad Will start and idle ok, when I open the throttle it will rev all the way up until WOT and then it dies back down to idle, and if I keep the throttle wide open it will rev back up. It will do this over and over and over.
I replaced the carb, (twice), Rectifier, battery, and spark plug. The Stator ohmed out to the proper specs from dinli. The other issue i can see is I’m not getting 12v on the choke circuit. The lights don’t work either.
possible bad key switch? Maybe the new rectifier is bad? All the contacts on the key switch also ohm out properly
comprsssion is up to 125 psi and spark is there.
Reed valves look great.....
im at a loss. Any trouble shooting advice would be appreciated.

I just recently bought a 1994 Yamaha Timberwolf 4x4 from a buddy who had the wheeler sitting in his garage for 7 years. I got it home and fired it up pushed it out of the garage and tried to shift it and it wouldn't shift. First it would click like it was shifting, but the wheeler wouldn't move and when I hit the gas it revved up like I was in nuetral. After trying some more it became stuck in 1st gear and wouldnt shift at all. But it later broke loose agian and acts like it is in neutral again. I took the motor off the machine to make it easier to work on.After asking friends they were convinced it was a clutch problem but after opening up the casing for the clutch I don't see anything out of the ordinary and am concerned that it may be a transmission problem. Any help would be greatly appreciated thank you.

The Hop-Up: You may be saying to yourself, “that’s a chick bike,” and you’re right. But honestly, it’s so much more than that. It’s one badass bike. http://www.quadmagazine.com/quad/features/article/0,24942,1587044,00.html
