Hey all! I'm attempting to rebuild a FUBAR City X and turn it into a XBR track bike. I have almost all the parts I need for the conversion but might part out the stuff if the engine is a gonner. I doubt the engine is irreparable as the damage seems superficial. I would hate to part it out as it's like admitting defeat, you know? I spent the afternoon dismantling the bike and got down to the engine, which I don't know even runs. I was hoping someone could give me some pointers. The pics depict a damaged primary cover and points cover, and bent pushrod. I disassembled the front head and removed the push rod cover and replaced the bent push rod. The lifter doesn't appear to be damaged. Now, the top of the piston and the cylinder wall had this flaky layer of black residue. I wiped it with a rag and it came off pretty easily. What does this tell me about the condition of the engine? Under the piston, I could see the crank shaft and it looked ok, but it was black and I don't know if it's sludge or not. I will look further tomorrow. I am looking for a replacement points cover but once it's together, do I have to assemble the whole bike to see if this engine even runs?
