Hey guys, I have finally built up the courage to ask you for some help with my bike. There are some extremely bright folks on here and i admit it's a bit intimidating So here goes! My bike (1999 YZ400F) is currently in a reputable shop getting some work done. I put it in the shop because it was blowing coolant out the overflow (head gasket failure). The shop has a full machine shop so i figured if the head was warped or anything that it would be a great place to bring for this situation. The shop found that my cams were heavily worn and that they were missing the "clips" i wasn't sure what they meant by that but you guys may. They installed a new set of hotcams and a head gasket. They were trying to get it built up and ready to roll today but they discovered that when they started it it idled extremely high. Could the hole where the auto decompression lever was once installed be creating an air leak? I also though about it possibly being the throttle position sensor. Any help would be greatly appreciated! The bike has been in the shop since july 30th and i'm getting antsy to ride. If you need any more info please ask!
