Okay guys I have an 05 Eiger 400 auto 4x4 that runs bad and pops but if you rev it up it starts to clear up and run okay but runs horrible at idle. I have installed a brand new carb rebuild kit and it still runs bad. I have pulled the carb back apart and found no crud or sediment to be clogging it in any way I'm at a loss of why it's running bad any help is appreciated

Try  adjusting the idle  air  screw.  Also  may  be  valves  set  a  little too  tight or  if  the  timing  chain  is  loose it  may  have skipped  a  tooth.  I'd  try  the  idle  air adjustment first , then check  for  vacuum  leaks. If  that  doesn't  do  it, pull the  carb again  and  make sure  all  passages  are  clear  and  jets  checked  for  tiny  missed  holes .  Blow  the  passages  out  with  "Canned  air"  for  cleaning  computers  and electronics  if  you  don't  have  access  to  a compressor.    If the problem  remains  then   you'll  have  to  dig  deeper and  check  valves and  timing.  Usually  running  fine  at  idle  and crap revved up  or  the  reverse  indicates  a fuel   rich or  lean burn problem.

      1st problem, Does anyone know where I can find a stock carb for my Timberwolf, I have tried two different aftermarket carbs and they both suck. The machine runs great until it gets good and warm, then it keeps stalling unless I feather the throttle. it will even stall while I'm trying to go from 1st to reverse or vise versa. I took it to a buddy of mine who is a bike mechanic for years, and he told me try to find a factory carb. When I look online from dealers it says "NOT AVAILABLE" anyone have any suggestions ?
       
      2nd, The small tab on the rear axle for towing is to short for even pulling my small yard trailer, I can't even turn a little bit and hit hits. I tried making an extension which worked great as far as length, but it bends the tab and then the extension drags the ground. I have an idea of what to do to fix it, but wanted to see if anyone else has had this problem and see how you solved it.

      As the 2025 ATV Motocross National Championship Series (ATVMX), an AMA National Championship, got underway with back-to-back Florida AMA Pro only events, it was evident that Phoenix Racing Yamaha’s Joel Hetrick picked up where he left off last season.View the full article

      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

      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.
