wrt to oil my GG didn't smoke once warm at 50:1, but part of it is old bikes have a lot of residue in the muffler system & will smoke like a down town prozzie even without oil in the gas. The more you trail ride I'd tend to more oil. Trial competition has a while to build up reserves while idling. Either way if you get the jetting closer it will help a heap.
Repack the muffler & remove the primary muffler most trials bikes seem to have & give it a session with a gas torch to burn out old residue.
Don't you look at my accountant.
He's the only one I've got.
