Nothing major, just basic and not so basic maintenance.
Brake pads, fork seals, pistons, tires, etc etc.
Great bike all around. They are high performance machines and need to be treated as such.
I have never owned a 2 stroke dirt bike with such good throttle response as this one. That is what sold me on this bike.
My Kx 250 is not a good bike at all. Never have I had a bike with so many problems in my life. It seems like every time I ride, something new breaks.
I have replaced the transmission, which isn't cheap, and there's a lot more problems to list, so many that I can't even remember them.
I have a 99' kx250. I'm 14 years old, so it's a lil bit too much for me, but I'm 6'6 and it's the biggest I can get.
I haven't rode it much, but I plan on doing so. And when people say that they have so many problems, I haven't had one yet.
I own a 1999 (kx) 250 2 stroke and I love the thing.
I do mostly track riding, and the power always there.
I have not had any problems with this bike out of the ordinary. I rave the crap out of it, and the bike keeps going.
I am overall happy, and plan on keeping it.
I'm 13 years old, and I have a 1997 KX250 and love the quickness. It was my first bike, and has many after market parts such as Boyesen reeds, FMF fatty pipe, Procircuit KYB works kit front shocks, Procircuit rear, twin air intake, moose bars, IMS footpegs, and DP brake rotors. I've never ridden any other bike, but I ride trail.
I first had problems with the bike flooding, but then adjusted it because it was running too lean. I don't plan on getting rid of it, and I find it a good trailbike for wiping around turns, with instant throttle response for logs etc.
