These CVK's I have run 1.7/1.8 mains stock :(
But this thread + the other recovered thread have helped a #OOPS# load in my understanding on how to run these. I feel I might start better off getting the angle of the carbs right (I think you mounted to horizontaly, I forgot the position yours are in).

.

Never did never. Pulled carbs out again and cleaned the one that leaked. throughly! Found a tiny bit of old o ring In a Idle jet passage. I back flushed it and found it. Also the tang on the end of the float needles are spring loaded. This was stuck open. Soaked and cleaned and llama like new. Reset float and And all great! Smooth 1050 rpm idle still bit higher but car if anything is still rich at wot. Need to Install smaller mains.
But it has more go than it did when I thought they were ok before.
Idles nice and smooth and go full throttle it's great to 5500rpm. (Cam profile only between 2000 and 5500).
Going to enjoy driving it a bit til dyno.
Swap 1.7 mains for 1.3 and retune. I still think 1.4 or 1.5 may be the go.

Make sure your fuel filtration is spot on and I think you said you had the tank cleaned?
Also higher fuel quality needs to be better than regular for bike carbs as deposits is more common.

You will be a bike tuner soon enough the way things are going! :)

Got a nice smooth idle at 900 rpm with 13 afr. Then It leaked after 2 mind same vent hole. Raised idle to 1100rpm and leaned off to 16 afr.... no leaks after 5 min with nice transition onto needles.

I'd love to know why fuel comes out that air jet though.
Stock bike has idle between 950 and 1100rpm. I figure 900 may be too low and flooding main jet .

let us know how u go mate

Thanks. I've read that now and pretty much found similar conclusions lol.
Just pulled down carb bowls and cleaned again. It's amazing what you thought was clean before and how it's clean now.
I cleaned all jets again and found 2 of the pilots were not as clean as the others. I used guitar string last time but used micro drill bits this time.
The .40mm pilot jets should easily take a 0.35mm drill bit. only two of the 4 did, and the 2 dirty ones had some crazy on the drill bit.
reset floats a little lower too and will try over weekend. Too late to vroom vroom at 11pm.

hey mate

i don't know too much on bike carbs but hopefully this link can help out a bit.Seems the writer had same issues as you.
