My son and I recently found a running 1980 KLX 250 at a yard sale for $20. We decided it would be a good project for him and a good upgrade from his TTR 125 since he is growing like a weed and getting too big and fast for the poor little 125. He also really likes my vintage bikes and wants one of his own. I rode one of these about 20 years ago and while it seemed like a good bike it was not big on power. We're looking for any info we can find about parts, maintenance, modifications, etc... Any suggestions would be appreciated.
