I did also forgot one of the long exhaust pipes not the bend one at the exhaust end but the straight one. The exhaust port instead of the muffler in the engine area that quite is similar to the one on my Kyosho sidecar 750 but I guess that during that time in the 1970's for this bike it was chop to fit.
I'll be back once I get the laptop fix. My 2 year old slap the living crap of the keyboard and left us without it for almost 2 months now.
Thanks to the library computer room, I have access.
