Went out for lunch...

never I've discovered that it is very easy to "adjust" the card and have had good results so far (much more mid range - I want low end and mid range there is plenty of top end for the riding I do). I have a feeling I can do better still using the info MX_robs thread re getting rid of the lean spot just of idle, getting the needle in the right position (and stopping needle/needle jet wear which isn't good at the moment) and getting the pilot screw set correctly (very easy now I know how to do it).
The only modification I've made so far that is not easily reversed is the hole in the slide (which I do doubt the worth of) and the only other one I plan at this stage is the spring cut. Maybe one day I'll get the ktm 640 needle and make an extra hole in the air box but for now I want to get the stock parts to work correctly.
It seems that Suzuki were so close with the Yanky spec and with three very minor improvements can make the bike not only run better have less wear in the carb!!!! Interesting that MX-rob found the stock yanky main and pilot jets to perfect for the close to stock set up though - who needs dyno jet jets

was that you riding along pasr atawhai about 430 pm sat avo nordie?
Did the 7mm spacer, pilot jet and spring cut today. The spring cut works really really well. I can now ride around at 45kph in third gear the the bike is running smoothly. The spring makes a huge difference to smoothness.
I measured how much the needle was protruding from the bottom of the slide before and after the mod. The needle is about 3mm higher with the mode so I'm not sure about the needle lift yet. I'll give it a tank full and see what happens to the fuel economy before I make a judgement on this. The wear on the needle and needle jet means it is probably a bit rich. Seems to pull well but I wouldn't say it has strong wheely grunt though -feels very similar to when the needle was 3mm lower.

7mm spacer? Ah yes...
I didn't do that as I felt that by shortening the spring about 3mm (or less) you're increasing stiffness and reducing preload which will let the slide respond quicker off the bottom but slower through the midrange.
Just realised I've been riding around for a week with the needle and spacer in my pocket
Dont worry. After reading all 61 pages of MX_robs thread I realised that I need to stay with the 6f23 needle anyway.
I'm half tempted to get a set of plastic washers about .5mm thick and make a stack 6.5mm thick. This is to allow for the wear in the needle and needle jet i.e. needle .5mm lower and the plastic stack so I can easily adjust the height. I have to file a spacer to length at the moment which is a PITA.
