everytime i crank it up it runs fine... but after i ride for a lil while at high speeds..... when i let of the gas it revs high? anyone know which hoses run where? theres two that come out of the tank? maybe they could be hooked up backwards?

those 2 hoses comin outa the tank are your fuel lines to the carb. one for regualr the other for researve. Thats not your problome. My 125m did that same orta thing..eccept it would do it when ever it is cold also..it would be idiling and all the suddon rev up. I knew it had an air leak somewhere. I bought a carb rebuilt kit ( o rings and gaskets) and now it runs and idles like it was new. Sounds to me like that is your problome..

carb rebuild only consist of o rings and gaskets?
