My next move is to adjust the valves.

BTW... Main Jets are 165 - not 160 as they should be.

On a side note. I bought this bike "uncertified" for what I thought was a decent price. Why do previous owners always bugger things up by adding OR subtracting from a perfectly good motorcycle? Today I discovered that I have the wrong center stand installed.
Take appart carbs and measure everything and clean everything. Set valves and clean filter .... start from Veronica. Balancing the carbs by ear is the easiest thing to do. Engine off ... see that both open at the same time. It will be pretty close when you start it. It is not the voodoo you fear. Unless you are absolutely hearing impaired they will be ok.
