Usually, even for larger motorcycles, they try to keep a 2ft length, just to prevent the flame from going back to the valves in case of lean burn.
The diameter really depends on the CC.
For a 300cc single cylinder, the tube dia should be about 1 inch; so I presume that 3/4 would be good for a smaller one.
You can get cheap mufflers online, but should you have the time to make one, just drill a hole in a 6-10" dia tin can (off center) on both the entry and exhaust side, stuffed with rockwool, and chicken wire to keep it at it's place (or a perforated pipe), and weld the can on the exhaust pipe.

I got the bigger 17.5kw generator so it's not crucial.
I would like to build it at least so the CO goes up and away from people.

My 17.5kw is broke down, so this is definitely back on the table.

That sure is a lot of juice you're using. 17kw is about the max I could draw at home (heaters, oven, and everything else). 7kw would be enough to run the place as long as I payed attention to what was on at any given time.
I wouldn't want to pay the fuel bill on either, though!
