Hey Dingo
just spruce up the carb and ride it. make sure the tappet clearances are set at the 'sixth of a turn' and also that the ignition timing is as follows
the white line that you can see through the hole in the cover is about 1mm to the left of centre.

at the altitude you're riding at I would suggest a couple of smaller MJs as well and then a little experimenting. the easy thing about altitude riding is that you are testing the bike's jetting without changing it just by going up and down. testing is very easy although a compromise is always a balancing act.
