I am not a carb tuning specialist, but I can try and go over the charts with you and follow the changes so you can better understand the changes you have so you can make a educated guess for your next move.
But before we go there, a leak down test is really should be done and yes a pain to do the first time because you do not have all the pieces but once you spend the time making up what is needed than after that it really takes no time at all.
If it checks out OK then lets look at your jetting pieces, going by the needle chart supplied by Keihin the change from a CEL to a DGH should have made the following changes
1st letter is the Taper
2nd letter is L-1
3rd letter is Diameter
C to a D You richened the 3/4 throttle position but also the 1/4 to WOT
E to a G You Leaned the 1/4 throttle position but also the 1/8 to 3/4 throttle
L to a H You richened the 1/8 throttle position but also the idle to 1/4 throttle
You ran the CEL clip at richer clip position so it could be said that you leaned the 1/4 throttle even more than the amount predicted by the chart when you changed to the DGH
seams like a DEG may have been a better change
