2002 KX250. Up until today the bike was jetted spot on. I have to take it easy for a few more weeks and the bike has sat for 3 weeks. The last ride the bike was perfect.
Long story short, the bike bogs bad under full throttle if wacked from at/near idle. Brand new condition. It will die if you simply hold it open. If you are riding slowly, pin it and it will bog/die. Roll off a bit and it comes to live with a vengeance sending the front end straight up. Pull on the choke: problem solved. Lack of fuel I'd say.
The air filter has a couple rides on it but I doubt it's very dirty. I'll check that first. I'm suspecting a restricted needle jet or main jet. The carb. will be pulled a part second.
So what do you guys think I'll find? Place your bets!
