I brought a YZ250F 2002 a few days ago. took it for the first ride today. Bloody great to ride, but noticed when in top gear either full tit or half power it felt like i was cluching it but wasnt. has anyone had or having the same probs. and knows why. the guy i brought it off reacons he hasnt had the prob before, even tho this is the 1st time i have riden it since he sold it.
