i have a 2006 yamaha wolverine 450. i recently pulled the carb apart and cleaned it as it would not idle. previous to the carb clean it would start up, idle, but then as soon as it was given any throttle it would stall out. After the carb clean and the fuel tank being emptied and fresh fuel being put in, it starts and idles extremely high and when the choke is on it idles even higher, and if given throttle it idles even higher without choking itself out or stalling. i have the idle set as low as it can go and removed the plate on the carb and the throttle cable is resting against the stop. I have adjusted the air fuel mixture screw, which was 2 turns out to begin with. I opened it to 4 turns out and it didnt make any differnce to the idle. In order to get it to idle down i have to cover the air intake hole about 80% but then when i give it any throttle it stalls out.

yes the throttle cable linkage was removed, and as for the choke it idles up even higher when i open the choke, and then back to the the initial high idle when i close the choke. Some buddies thought it may be the slide sticking open or an air leak, but i checked both and they fuction properly.

      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!

      My name says it all. I have a '03 Honda Sporttrax 400EX with a new aftermarket carb on it that seems to be having issues. I can start it but it idles really rough and when I give it throttle it just kills the engine. I have tried adjusting the idle screw but to no avail. I am in the San Diego Ca area. 
      Any advice will be greatly appreciated. I would also like to get an owners manual for the thing too but can't seem to find a downloadable one.

      So I’ve got a 2000 Honda 400ex absolutely love it!! I’ve had it for about a month, I ride with bruteforce 750’s, outlander 850’s and 1000 sxs’s and I was thinking of getting a trx450r carb and a full hmf exhaust. And probably doing the air box mod too, how much power would this give my 400? Just a little different or a big difference? Cuz if it’s not much of a different I’ll just stick with my dg slip on..... thanks!

      Im aware that this relay needs a positive (+) and a negative (-) to activate the other side. The blue wire is the neutral wire so when in neutral it gets ground. The green wire is from the parking break; when you pull the break in it gets ground (-). however one of those two needs to be neutral so that the positive from kill switch can go to the starter relay. The ground from the starter relay is from the start switch. Which one (neutral or parking break) should have a positive (+) voltage?
