its not blaster related but i have an rm 125 2 stroke and im having some difficulties. in first and second it wont reach full powerband it stops short and doesnt rev out compleatly but once i put it in third it straightens itself out and takes off. iv gone through the carb and cleaned it. i was thinking top end needs work but the fact that it cleans itself up throws me off. any ideas would be greatly appretiated!
