Blisster, my only advice on the saito is check the valve clearance before fireing up because there have been a very few that have been a little off,(just in case)set to .002.
and to save you a little trouble with bearings..... run dry and use aro after every session and it will last a long time also check your valves often at first (first couple of hours running) then you can slack off if they seem to be ok then.

the saito will seem a little rough at first, dont panic, it wwill settle down after you get a couple hours on it and you get it leaned down, it will also get better fuel consumption as you get the low end down. after a gallon or so i usually just get it to idle then turn the low end down 1/4 turn at a time till it dies(give at least 10 seconds inbetween turns) after it dies then open it up 1/2 turn and your gonna be close then and you can make final adjustment from there(small adjustments)

good luck!!
