What does your Plug look like?????????

What adjustments did you do to make it work......Just Air Mix or did you replace any Jets???

The air screw is most effective between idle through 1/8 throttle.

The pilot (slow) jet is most effective between 1/8 through 1/4 throttle.

The slide valve is most effective between 1/8 through 1/2 throttle

The jet needle is most effective between 1/4 through 3/4 throttle.

The main jet is most effective between 3/4 through wide-open throttle.

Did you clean your filter????? If you dont have a Pre- Filter,,,,,Even a pair of your Moms Pantyhose will work.....

Dont tell my wife.....But I have a Pair of hers on my Sons Drilled Air box....:laugh:

the bowl drain screw is right next to the drain hose on the LH side. see it?

mixture can make it bog. are you mixing fuel and oil or using the pump and the tank?

try a new spark plug.

hey looking at your carb pics, your oil injection port is open to the atmosphere!

there's a lean vacuum leak problem! get a little block off nipple from an auto parts store and slide it on there! It's on the RH side, towards the front, it is the larger of the two, above that big plug but below the little brass plug. This carb is used on many bikes n stuff that's why it has so many blanks cast into it. It's not a BIG leak, but it's a leak.....that's where your injector pump pushes oil into the engine.

Did you change your main jet when you installed the pipe? you might look at that too. loosen the mounting clamp to the intake and rotate the carb so you can get the bowl off. the main jet is in a little holder up inside the bowl. it has a number on it. let us know what that number is OK? watch the color of your spark plug- if it is light brown, then this may be unnecessary. If not, maybe we should look at it.

That is exactly why we added you to the team! Thanks for the great info Raptor8.

ok i need this question answer quickly before i might make a fool of myself. my friend is picking up a 2008 honda recon 420 tomarrow and i dont know if i should race him or not. im pretty sure i would beat him but just going here to have some questions answered first.

1) obviously, he will beat me on the trails. but any hint on how to outrun him making him feel like an idiot?

2) any mods i might want to get before i race him? nothing toooo expensive

3)do you think i will win or not? im a pretty good rider and he used to have a big bear 400 that he rode like once a month and never got out of 3rd gear, so hes not the greatest rider. like they say. its the rider that wins the race, not the bike

Thats the truth man its the rider not the machine i got a honda recon 250 and i smoked my cuzin on a 500 formen honda but he aint that good of a rider and i know the 4-wheeler can out run mine if he rode it rite.

      New to the ATV world, picked up a solid used Kodiak 400.  It appears the former owner did some sort of modification for a saddle bag or something along those lines--and I'd like to match it up and replace it.  Not a big deal by any means but something I thought I would give a shot at finding.
      does anyone recognize what kind of luggage/bag/cargo would go where those white tabs are he drilled through that fuel fender?
       
      Thanks again

      My ranger crew 700 is hard to shift and gets locked into forward. When trying to shift into reverse we have to shut engine off. Shift then restart. Checked linkage and gears are fine. The RPMs arent really that high but did notice a little improvement when we lowered it. Did notice the throttle cable looks damaged. Could this be the issue?

      Let me start with I have about 30 years of ATC experience, but not much with stuff made after 1988.  Some, but I'm mechanically inclined so it's all good.  I"m rehabbing a 1997 Bayou 220 to send back into the wild and the mechanicals are now all good, just working on making the electrical system...electric.  Right now, I have no power on the white wire as tested directly on the plug at the starter solenoid.  I'm assuming that wire is supposed to be hot any time it's attached to a battery?  The genius that had it before snipped a couple wires and inserted a fairly heavy push button for electric start bypassing the electrical system. I think i've corrected everything north of the solenoid but the white wire has me stumped.  Is my assumption that this should always be hot with a hot battery correct?  Does this indicate a broken circuit in the starter solenoid?  Relay was also bad and wired incorrectly, but that's resolved and I can make the relay click bypassing the solenoid and connector, directly giving the white wire 12V.  Thoughts?

      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.
