If it will run with the choke on that means it is not getting enough fuel. Did you physically remove the carb and take it apart. Use a torch tip cleaner to get in all those little spots. Check the petcock valve, does it have fresh gas?

love the 350 warrior !!! Try cleaning the carb. & also look for any air leaks . Air leaks meaning around the intake manifold. Have you made any changes to the pipe, air filter etc....??? it is for sure not enough fuel if it idles with the choke ! if no changes have been made start with cleaning & looking for leaks around intake as well as checking your air filter to see if it has a good seal.. if any changes have been made & you have adjusted the pilot screw then you have either a pilot jet issue or the needle clip issue ....need help feel free to email I have been through the mikuni carb many times!

What he said.

Check your valves, they may need adjusting. If they are ok, then try adjusting the pilot screw on the bottom of the carb, that will help richen up the air/fuel mix at idle to 1/4 throttle. Your problem could be that the motor is just getting tired and needs a rebuild, do a compression test.

Have you just purchased the bike like that or is it something that has just started to happen? Have you made any changes to the bike as far as pipe,header,air filter? Many ATV mechanics will tell you the Warrior does not need much when making changes like that ,"THEY ARE WRONG!" I was told by several that they do NOTHING but maybe change the MAIN JET, if at all that ....................... WRONG ANSWER!!! It depends on what you have done to the bike & elevation,compression etc....... I put on a FMF header,FMF Silencer, K& N air filter & I had to change my main jet,pilot jet & adjust my needle clip ....... Do not get down it takes patients & usually is something really small & simple !!!!!!

      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!

      I like to ride in wooded and grassy areas. It takes my mind off the everyday routines and helps me deal with my father's cancer. Also gives me a reason to get involved with forums like this one.

      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’m brand new to 4 wheelers and just bought a 1987 Yamaha Moto 4 350. It has good compression and fuel, but no spark. I’ve looked high and low trying to find how to test all the components of the ignition system, but can’t find anything. This has a new CDI box on it, but I suspect it might be the stator. How do I test the stator on this? Any help would be greatly appreciated!

      Does the 1987 moto 4 350 have a low oil sensor that kills spark? Or are these too old for that kind of thing?
