+1 on this. The idle tells the story.Walms said:It seems to be hanging on to the rpm when you let off the throttle... an Air leak or too lean maybe?
johnu said:Ok great feedback! It only started with the revs not going down since I put the small pilots in. I will research "leak down test" as no, I have not done it. What are lab seals?
Going to get a video of me riding the bike when my son comes home on leave this week
johnu said:I just went too low with the pilots.
Walms said:Here's a short video of my bike on first start up. It's dead rich, probably too rich to ride but at least you can listen to how the rpm drops quickly.

HollywoodMX said:Shit I'm confused. I didn't look to who I was responding to.
teazer said: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.

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
