My Warrior seems to have a high idle. When I turn the spring loaded screw out it idles down but then the engine will start backfiring through the carb after I ride it for a little. It will die and have trouble starting after it's warm. The screw below it I think is Air mix screw but I can not screw the screw in or out. The screw below it may not be the air screw but I can't see any other screw.

      Has anyone had a suzuki 230 quad lock the engine up?

      Has anyone had a suzuki 230 quad lock the engine up?  Its a well maintained bike, it locked up when my son was riding it. Pulled the plug, it has connected with the piston. I'm thinking the con rod let go.  I don't have a service manual.  Does the engine need to come out to check further?

      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.

      '03 Honda Sporttrax 400EX Carb issue.
      By Dumass
      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.

      400ex with 450 carb??
      By Trent Finnessey
      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!
