I just bought a 2006 rm125, the first thing I noticed was that it idles low and if I don't blip the throttle it'll die out. I also noticed i had the lay the throttle on slowly for it accelerate smoothly without bogging But I was just cruising around my neighborhood 4th gear maybe half throttle and it bogged out and wouldn't start. When I got it to start again it seemed to have no power at all and would stall after a minute or two. I ended up taking the carb out and wasn't dirty, but I touched it up and made sure the jets were clear. I'm thinking it is a problem with the carb but everything seems to be in good condition. I was also wondering what the factory settings for carb are. Also, according to the previous owner it has less than 4 hours on a top end rebuild. Mid someone could help me out that would be great.
