I have a question about my Idle Screw. I just recently bought a like new kfx450r and this weekend I took the bike out for a ride. While I was out riding I noticed that the bike started stalling out or breaking down. basically it just shut off during my ride. I jumped off and tool a closer look at the bike and noticed that the bike was running with the idle screw pulled out the same way you would pull your choke out on a carbuerated bike. I tried riding back to my truck and pushing the idle screw in but that made the bike totally break down as soon as my thumb was off the throttle later on I could start up the bike with the idle screw pulled out again. What do you make of this? I have the screw turned 24 clicks to the right I might mention.
