98 610 bottom end sputter?

This is the latest chapter in my 98 te610 restoration. I got this bike running after it sat on the side of a guys house for 5 years. It looked pretty rough but cleaned up O.K. I wish I took some before pictures but oh well. Anyhow, the cdi was the problem as I revieled in a previous post. Now, after a valve adjustment, it's running well except for a stutter at the very bottom, just off idle. I have cleaned the carb twice. It has a Big Gun header and Pipe, K32 needle, 68 main, and the other two jets are 60's in a stock Dellorto. Does any one have any suggestions as to what to try next?Thanks for all help.

I would adjust the fuel screw, it should help.

run some fuel system cleaner through, BG44K works great, for 2 gals of fuel a shot glass is all that needed,
for real dirty carbs,,,try to shot glasses..you will be suprised how well that works..
after my bikes sit for more then a month, a shotglass per tank...the bad?
