My first Dr I picked up was a 1992 dr250s new piston, rings, valve job only 3231 miles on the bike and clean. Lots of new stuff battery, petcock, tires. But the previous owner claimed it needed to be timed, he claimed the shop that did the work didn't have the service manual to time it and he got the bike back not running and lost interest in it. I asked lots of questions before I made the hour an a half drive to see it. All made sense price was right so It became mine. The bike is now my parts bike ,because for some reason the valve cover that po must have replaced was off a 94' or newer dr with Auto decompression. And not compatible with the 92' manual decompression head. Finding that valve cover was like finding a unicorn. In searching for one I ended up buying my first 91' dr350s which is one of two running 91' 350s I own now. Just short of the jug and head the 250 is a compatible parts bike for the 350's all three pre 94' model's. The past 7 months have been quite the learning process. Thanks to forum's like this one I've been enjoying the bikes and experience very much. Learning something new all the time. P.S. pictures can make a bike look a lot cleaner then they actually are in person.
