i bought a 2001 rm 125 3 years ago and when i got the bike it ran great and had good power. after almost a whole summer of riding the bike started losing power and then it came to a point where it wouldn't start and lost most of it's compression. i took it to my local dealer and they said it siezed the piston but the motor wasen't locked up. they put a new jug on it along with a top end. i got the bike fixed in march and it sat untl late april. i drained all the gas out of it and what not. i took the bike out and broke it in. the dealer said to take it easy on it through the first tank of gas and i read the maual and broke it in the way they both told me. I had gotten about 4 tanks of gas through it and i was going down a dirt road and shifted it into 6th and got to half throttle and the moter locked up and before i knew what was happening it came loose again and i pulled in the clutch trying not to cause any further damage. i stopped and the bike was hotter than it had ever been before/when i touched the pipe. soo i let the bike cool down and tried to start it but it was locked up. i took the bike home and took the head off to see if it blew a gasket but it looked good and there was no antifreeze that leaked into the cylinder or on the piston. the next morning i went out and the bike wasen't locked soo i kicked it over without starting it to see if anything sounded different. it had a clunking noise and it would lock up again, i could get it to unlock if played around with the kick. this time i took the bike apart my self to see what happened. i took the jug off and saw it was kinda scuffed up along with the piston.at tdc the rode can move up and down about a 1/4 in. the crank also turned blue on one side. the bike has a pro circuit platnum 2 pipe with a 304 somthin scilencer. if that has to do with anything . i need to know should i fix or sell it the way it is. is it worth keeping.
