[QUOTE="jackdrinker, post: 710907, member: 41118"] okay, i have a 1993 rm125 that has become a project since i got my 250. the bike has never seemed to run right. it has nothing from the bottom when you crack the throttle open and makes a bog sound. if you give it just a tad of clutch it starts to rip. i know 125's need allot of clutch but not like this. i have messed with jetting and still have had no luck. well i'm rebuilding the bike and my chick is going to learn how to ride. i took the head off today and examined the head, exhaust valve and piston. this is what i found. the valve has zero tension and will not return on it's own. the rod seems slightly bent and there is carbon buildup on the head and piston. see the pic's and tell me what you think. thanks, jackdrinker [/QUOTE]
