Hi all,
I have a Dragonfly which has the original carburettor, and I have replaced all of the correct jetting and needle slider with new replacement parts, and the bike still continues to run lean.
I have previously read a few posts on here suggesting the difference with todays fuel as opposed to the fuel of the 50’s might call for slightly different jetting and slider.
The post that I read suggests running with a No3 cutaway slider and a 150 main jet, then lower the needle to its lowest point, therefore making it richer.
I have tried this, and the bike does run richer, but it also idles far to quickly to the point you cannot alter the idling speed low enough with the screw.
Now, before I start messing around with too many different things, does anyone have any advice to offer or things to try.
Thanks in advance, Stuart.
