rebuilding old bikes is often a way full of adventures in finding good used parts...
in my case with my 83 kx250-rebuild it was very hard .. i just bought this bike 2010 in bavaria for 150€, the owner doesnt know the right year , complete disassembled, worn 2.and 3.gear , missing the carb, later i´ve seen that both fork legs were bent
and at this time i had my newer-bikes-knowledge and knew only ebay-germany and even the kx-dealers for getting parts. i had to learn so much and to find the guys that offers new and good used parts for old bikes.
later with my kx500sf- projekt i found this site and many new knowledge of the great guys here..
now with the 87-project it was easy to make in ten days... the bike had a good base with an fresh top end, the usd-forks, original forks and 2.engine without cylinder .the exhaust pipe was badly worn. many needed parts i had in spare like the frontbrake-master-cylinder, wheel- and linkage-bearings and tyres. the half of the rebuild-time i was waiting for the ordered spare-parts that came from netherlands. last part came the day before the first planned race on june 2. 2013.
so it was real fun to do is in the short time
then the raceday was an mud- and hard-rain-disaster, but thats another story...
