Shit I'm confused.  I didn't look to who I was responding to.

Walms and JohnU are both correct.  Walms bike was way rich and JohnU's bike is NOW too lean at idle with those 22.5s where it was too rich before with larger pilot jets. 

So it needs slightly larger pilots but probably needs to be leaner as it comes off idle.  That suggests a larger cutaway might clean that up.  I also wonder if the pilot air jet system is clogged or maybe the air jet is too small to have any effect.  I think it's a drilling in those carbs and it's worth checking.

Going to take the carbs off today AGAIN!! and check them AGAIN for any blockages ;)

John,

The situation you had earlier appeared to be rich at idle or was it just off idle as you started to open it up?  I don't have a full picture of what the symptoms were at different revs/throttle settings with those different pilot jets and air screw settings.

In other words, if you can get the idle OK with say a 30 pilot jet but it bogs as the slides are lifted to say 1/4 open then it is likely to be an issue of transition from the pilot circuit to the main circuit and that's where the cutaway comes in to play.  If it's wet and soggy at say 1/4 to 1/2 it's more likely to be the needle jet. 

Easy check on the air circuit would be to remove the pilot jet , loosen the screw and spray carb cleaner down teh air inlet.  If it sprays back in your eyes, you know it's blocked (and you need to see an eye specialist)  If it sprays out of teh pilot jet holes (up or down) it's probably not a problem.

I would put in the 35s or whatever you have close to. I would lean the needle 2 clips.

Start the bike. Let it warm up. Test the air screw. If no notable difference, Then with one hand hold the throttle to around 2000 rpm steadily as possible , with the other hand adjust the air screw and see if there is a difference in it idling up and down then. I would also take it for a quick boot to test the needle change.

Ok guys, thanks to all of you that voted for my bike this month!

Everything will be at a standstill for quite a while as I just unexpectedly had to have open heart surgery!!  I have had a pacemaker for the last ten years (when i was 40) because I have a very low resting heart rate (about 40 during the day but dipping in the 20's at night) well last week they removed the pacemaker as it was giving me grief but when the took the wire out it tore the wall of my heart so they had to do open heart surgery to repair it.  I am very fit ( i can out cycle most guys half my age) have no clogged arteries or bad valves so hopefully I can recover quickly :) 

Probably going to be about six weeks before I can fire the bike up again :(

I hope you recover quickly. Don't worry about the bike, it will be there when you get better. Taking care of yourself is priority numero uno.

I hope that you get recover soon. From what I see here, you seem like a really good dude.
