just if u need the std specs 465 g , 400 , q-2, 6f16 clip in pos 2 , 50 465h 390 , q2 , 6f16 clip in pos 3 , 45 , both have #3 slides , the first thing to do would be to buy new needle and needle jet as they wear , and the wear will be greater in different area,s according to how the bike has been used ,if the bike has been used for trail riding it might be worn where the taper starts and check the slide for wear as well, some people say (thanks rusty ) a leaner slide is of benifit , i have a #4 in mine ,makes it nice off the bottom , put a new float valve in it as well , a dg pipe might make a slight change ,perhaps u might have to lean it up one point, but i wouldn,t ,tune shouldn,t change too much in different gears , what is the top end like ? check the base gasket , use rusty,s advise , make it wider around the transfer,s and use permatex , i can,t give u specs i,m using as it,s completly off the chart , big ports ect , float level , book says 27 mm from carb body to float with arm just touching needle , does any one know the actual fuel level in the bowl like the way kawasaki uses ?
