Update: I ended up blowing up this stock KTM 65 cylinder, then put it up for sale. A kid from Chicago bought it then paid me to rebuild the bike like I would want it to be. This bike was built as study of "can this work". Some things needed to be tweaked and fixed or adjusted. KTM 65 cylinders are hard to come by cheap, used, and in good shape. There are 80cc big bores out there but they are expensive, but that is the route that we went. I did the big bore, had to moddify the cases again to clearance the cylinder skirt. I went from a bone stock 2 shoe up to a braced 3 shoe clutch. We added the v-force reeds for the Dio intake. I also did things like add an electric water pump from an older VW Jetta or something & re-plumbed the hoses for better cooling. I then straightened out the swing arm and re-centered the wheel. We also put on new tubes and tires because the originals were old and crusty. After all these mods were done, I put a handful of miles on it and away it went to the new owner. I built this bike around wanting to build a watercooled E50 motor. After getting a box of messed up cases a friend and a used KTM 65 cylinder, I started to build the motor. Once the motor started to come together, I had acquired a bunch of frames and forks from someone that bought out a storage unit. Turns out it was another buddies discarded pile of parts. Once i had frame and forks picked out, everything came together. Almost everything came together from other peoples discarded crap, and thats cool, it gives it some character. But for me, i wanted to put together a safe bike, and one that i can say that i built almost every part of.
