YZ400f Questions!!!!

2 posts in this topic

I just bought a 99 YZ400F for $800 bucks. The guy said that it had sat for about 3 years in the shed and probibly just needed a fluid flush and carb cleaning. I figured I would adjust the valves while I was at it. Can anyone tell me what the specs are on the valve adjustment? And I also need to know what the stock settings are for the 39mm Keihin. Also, where is the cheatpest place to buy a repuild kit for the carb. Any aditional info would be great. Thank you very much...
