@Kris, how much shim do you have in the needle, if any?
@Dave, well it's in a good position now with the 55 at two turns out, and (correct me if I'm wrong) but wouldn't the Dyna have a effect that would tend to lean the engine if anything? Once I get the Dyna on and reshim the needle, I'll see how it idles then and go back to the 52.5 if necessary, but the 55 is not causing any idle issues atm.
EDIT: OK just gave it another test, this is after a complete blast out of the filter with compressed air, after 6,000kms still in good condition. Carburettor float boat was completely clean when I took it off, everything nice and shiny. I currently have the 55 pilot jet at two turns out and it started up fine but more importantly it was idling at the correct speed which sounds to my ear at 1200. I then took it out for a 30 minute ride, upon returning home it was still idling at the correct speed of 1200 (to my ear). With the old 52.5 pilot jet, it needed a few minutes to warm up before the idles settled down to 1200 even on a hot day. If I set the idle so it didn't need to sit there for 3 minutes warming up then it would be idling too fast when it was warm.
But now it idles perfectly from cold and does not speed up when warm. OK maybe a bit but I'm doing it by ear.
Then I checked the idle mix when warm with the 55 jet. It stumbles at 1 turn out and dies completely at 1/2 turn out. Seems OK at 1 1/2 turns out, speeds up a bit at 2 turns out starts to stumble again at 3 turns out. I ended up setting it to 1 3/4 turns out.
As for a riding test, I set markers on the throttle. I set the 0 point with all the slack taken out. At 1/8 throttle it cruises along happily in 2nd gear at about 40 kph, in 3rd gear at 1/8 throttle it cruises smoothly at about 55-60 kph which is the speed limit around here. If I'm cruising at 1/8 throttle in 3rd at 55kph and just open up the throttle to half way, it accelerates instantly with no lag and it's pulling strongly all the way to 90kph at which point I get scared because the place is crawling with poppo this time of year. Pulls just as well from 1/8 throttle in 2nd. It feels excellent.
At this stage I can't feel any need to adjust the needle spacers, but I will reassess after the Dyna install.
