GG 300 Keihin Jetting for altitude and spark arrestor?

Does anyone have a recipe? I'll be riding the CO national and know the elevation will be such that I should change the jetting on the bike - not that it will make a difference to me (no huge splatters for me!) but would hate to seize the bike on the loop trail or something.

I will also be adding a spark arrestor (Spanish Fly) which I suppose might affect things as well.

Thanks in advance, Jon
