Hey All, Need a little help here with my 06 RM250 potentially diagnosing a problem before I tear the bike apart....Went riding in the hills of SoCal on Saturday and everything was great until about 3/4 of the day. When riding my bike I noticed that the idle went up for almost no reason at all and the bike was idling sounding like it was running out of gas. I stopped at the truck and went to put gas in and noticed I still had a half tank. I started the bike on the stand and it continued to idle faster than normal and everytime I snapped the throttle the bike would bog then rev up. I also noticed a decent amount of smoke coming out of the powervalve vent hose that wasn't previously happening. Any ideas on what could be causing this before I tear it down? Id like to have a targeted idea before I go into it but Ive never experienced anything like this before ... Bike has been the same since last season, no jetting changes, air filter has 2 short rides on it....I assume the top end needs to be replaced as it has a decent amount of hours on it but never experienced this with a worn top end. Other than that the bike seems perfectly normal, no excessive smoking or other problems this just happened mid ride and I am baffled... Any suggestions?
