Don't really see a question there, but if you want to see if it will run, make sure you have spark, clean the carb and tank and use fresh gas. If all is well it should fire right up.

Since you have contact with the original owner, use this opportunity to get a thorough history of the bike focusing on any previous overhauls, modifications, and how the bike was maintained. You might be surprised what a DPO can do to these machines.

I like new fresh gas for a starter, a clean gas tank not full of rust and a good clean spark plug or a new one. I check for spark with the plug out and see if the key off or kill switch will eliminate the spark. I like to make sure the throttle is free moving. have a screwdriver handy in case it is over revving. I am not recommending this to anyone else, but I have been known to prime it with a squirt of gas from a oil can. Start it outside not in the attached garage. having compression is a must. ----------Clarence

Since the previous owner says it needs a carb kit, we have an indication that he thinks there is a problem with the fuel system. He could be right - or he could be wrong. As mentioned earlier, a thorough cleaning of the complete fuel system is in order - from the fuel tank to every single jet and orifice in the carburetor (especially the pilot circuit). The pilot (sometimes called the "idle") circuit has the smallest jet and passages and is the easiest to clog up. I highly recommend installation of an inline fuel filter - 40 year old steel tanks always contain some grunge. Use new fuel, non-ethanol gasoline is recommended. There is a website which lists gas stations which sell non-ethanol fuel. puregas.com? I'd recommend running pre-mix at least until you establish that the oil injections system is working properly.

Check oil level in the transmission.

Check spark as described above and be SURE that the key and kill switch will stop the spark.

And above all, have fun!
