I just used one of the threads in the Tecumseh forum to dial in my bike, so I figured I'd contribute what I can. This is a '70 Speedway Shrike from what I've been able to tell, and have no fear - it was already butchered when I got my grubby hands on it. I had to do an extensive amount of frame repair, fork repair and a new motor plate. While I was at it, an 8hp Tecumseh that I had sitting around went in. I made the motor plate and jack shaft tabs on PlasmaCam, and TIG'ed the sprocket/hub setup from Fleet Farm items. I worked at an upholstery class in highschool, so wipping out a seat from some awesome metalflake vinyl I found was a nobrainer - turned out awesome. On the to do list: chain guard, better throttle setup, and most importantly - BRAKES. This pig takes me about a 1/4 block to stop with my size 10.5 brakes. The peg that expands the shoes is snapped off, so if someone has one to spare, shoot me a PM. Also looking for pictures of the cable that was used, as I have not a clue how that goes together. Without further blabering, here's my form of transportation to and from class.
