I have a '96 Yamaha kodiac 400. Just rebuilt the carburetor and changed the oil and filter. It had gas in the oil and the air box. The rebuild took care of the gas in the oil and airbox. My problem is it smokes a good bit for about 20 seconds when I first start it when cold. After that no smoke but smells like it's running rich. I adjusted repeatedly the idle and pilot screws. This may sound stupid but could the height of the float affect this?

      Hello All
      I'm kinda new to ATVs. I just bought a 1987 Suzuki quad runner 230 Dual Range. I'm having a problem finding info on it. It's very clean, only 2.800 miles. The front wheels are only 30 in.center to center. I was thinking about adding wheel spacers to give it more stability. I realize the added stress on ball joints and bearings. I'm wondering if there are any other concerns? Any input is greatly appreciated!

      Hi my name is Greg and I just acquired a free 2000 yamaha kodiac 400 4x4 with the ultramatic transmission that does not run. I plan to get it going and use it around my property

      Troubleshooting a no spark issue, was running OK, maybe a little rich, turned it off, now no spark. I've checked/ohmed out the main key switch, the start/stop switch, neutral switch, brake switch - all good. It will crank the starter, but no spark with the starter or when I try the pull start. I've checked all fuses and diodes. Swapped battery. New plug. New coil. Swapped in a used CDI - no help. Traced, removed, cleaned, reattached all grounds. Removed things like my winch from the circuits to be sure a bad relay or something was dragging it down. When testing voltages, the orange wire going from the CDI to the ignition coil shows no/very low voltage-shouldn't it have 12V on it? Sometimes I get a very weak, intermittent glow on my spark tester, but not enough to fire the plug. I've checked continuity on just about all wires in the harness. Checked/cleaned/lubed w dielectric grease- all connections, redid a few that looked old/dirty. I've checked the stator resistances, all good, but have a stator and rectifier ordered anyway, will arrive Sunday. I verified that the rectifier has a voltage output back to charge the battery while cranking - 10.5-11V, low, but expected while starter is engaged. What else can I check as part of troubleshooting? I have a Haines service manual, but the 1999 350 4x4 seems to be an odd model, there isn't an exact electrical diagram for it, but found one for another year that has all the same number of wires and same color wires, so I've referenced that. Any hints, tips or advice would be appreciated! Thanks!

      I have a 2002 Kawasaki Prairie KVF 400 and im trying to figure out the actual float height... i have read 17mm +- 2mm, seen 13mm and 23mm... what is happening is it will start right up, rev a little and all is fine, when it warms and you put a load on it bogs down and sputters. no i don't have a manual
