Now that I am completely retired, I have been devoting a lot of hours to my bike building hobby, and since I have ratted out a bunch of old bikes for this very purpose, I can get right to it and I have several going at the same time now.(Note, I don't have a wife or kids any more so I can do whatever!) I built a YDS3 Ascot replica several years ago and I like these bikes and have a few to play with. This one is a bunch of mixed left over parts and bits from E-bay that I'm throwing together? I have a good YM1 motor and a DS6 frame to start with. The motor is bored .25 OS and mostly stock, I did find aluminum cylinders for it. The frame is de-tabbed and lightened as much as possible. The gas tank was a real turd, it was smashed in bad on one side and I beat it out as best I could and there is a bit of Bondo on it but it's good from 50 feet? The tires they allow on the track, 140/80-19 rear, don't fit the swing arm so I hacked and welded an aluminum one to fit the tire and the frame ( I think its a YZ250?) I shortened it as much as I could, it's still about 2" longer than the stock one, oh well. Also, I will change the front forks because the front tire, 130/80-19 rubs on the fork sliders, a lot! I'm currently searching for bigger ( Dia.) tubes and wider triple clamps to fit to it. I built high pipe expansion chambers for the Ascot replica I built, I will probably make low pipes for this one? I hope to build this one "on the cheep" so I will use as much old stuff as I can, also to clean out some of my parts horde? Here's a few photos from today; Sorry, my computer won't show my photos right now?
