During my last ride on my 98 WR400 my idle went high, and I couldn't get it to settle down. I figured my float was stuck, so I took the carb off and checked it. That wasn't the problem. I have very little knowledge about mechanics, so I didn't know what else to look for. I hopped on ThumperTalk, did a search for high idle, and found a thread by Frostbite with several pictures showing the slide plate in the carb when his broke. I used these pictures and the schematic to find it. Mine had not broken yet, but it had 2 large cracks in it. I spent $100 for the parts to fix it instead of paying $300-$400 for the dealer to do it. Without those pictures, I wouldn't have been able to fix it myself, and it could have done a lot of damage if it had broken off and went into the motor. The next time you have your carburetor off your bike, check the slide plate for cracks. I was lucky and caught mine before it broke off and did expensive damage to the motor. This is another example of how this website keeps the average rider on his bike. I have been able to do several repairs myself from the advice here. I would not be able to afford to ride if I had to take my bike to a mechanic every time something went wrong. Thanks to Frostbite, and to all you gearheads that share your knowledge with the rest of us.
