Thanks for the replies and link.
So I am here in NH, at an elevation of 900 feet.
According to my GPS, my elevations run from say 400 feet to 2500 feet where I can ride....but mostly no higher than 1800.
Quote:From stock,.. say, from a #145 to a #150 main,... from a #52.5 to a #55 pilot (although,. I did pretty well by actually going down to a #50 pilot... but, I'm at 2600ft) with a little more opening on the idle mix screw (1/2 to 1 turn more)... and a reduced spacer thickness on the needle slide from 0.1" to .066" or 0.50"... (you can sand the stock one down, or buy #4 nylon or brass washers to vary the thickness)...
Then from bone stock, which I am, the recommendations above would work, or no?
