Hi to all in KX land. I have been riding open bikes past 10 years in Ultima class at vintage events. I have an upcoming spinal fusion surgery soon,and am listing my 1981 KX420 on craigslist Seattle. I just purchased this and a 1979 KX250 builder from a good friend,but can't afford to keep. I will ride again,but in about 9 months to a year. I am in love with the 420,Very clean and has 46mm cartridge forks from newer KX.but reality dictates sale. I know someone here will appreciate the KX's as much as I do.
Jim
