this dog has no power,changed exhaust to fmf,opened air filter box and am running factory jetting.any good ideas on a new jet size would be apreciated.went to dumont dunes for the weekend and bike sucked,good for wife,no fun for me.

ask alba they do some stuff on 250ex's

The 250ex is a great bike for any one under 120lbs. If you don't fall in that catagory either ienjoy the bike or get a new one.

I wiegh 275lbs and ride my daughter 250ex for fun momentum is your friend.

| Yeah, what he said.

I have one also, great learning, newbie or small kids bike. Can only fix them up so much, you hit the rev limiter, which can't be changed (well, as far as I know)
