Kx 100 Junior grasstrack Bike And Complete Spares Bike

After a couple of practices my lad has decided that he would rather stick to trials than ride grasstrack. As such i have a Junior Antig grasstrack bike the frame is  approx 1993/4 with a Kx 100 engine fitted and a complete non working kx 100 spares bike for sale. I Bought the bike earlier this year and cosmetically did it up with new cables, grips and paint. The bike has always run ok, but the engine is i think about 1990 not 100% sure as the engine number has been over stamped kx100 but as it works ok i have not done anything to the engine. It has had the gear shaft conversion through to the right had side of the engine, this has been done by the look of the welding professionally. All the gears are there and it does go like stink! As its an earlier engine it does not have a power valve. I have fitted the bike with a 20" akront rimmed front wheel with a c90 drum brake and new motocross tyre which gives the front end a very wide grip footprint, the auction also includes 4 brand new 20" front tyre which are very hard to find. I also have a good condition kx100 exhaust and a brand new dep tail pipe which i will throw in. Cant really tell you much more, but i think it would be a good starter bike for someone. reserve set at £500. Cash on collection preffered.Cheers for looking Dev
