Cleaned carbs and now it will not start when warm

[xxBenJamminxx]

I plan on getting all the orings and such but now I know I need a #40 pilot jet as well as a new intake boot on the engine side. I was just saying if had gotten the o ring kit and then did it, I would have pulled off the carbs to do the orings and cleaning only to see that I needed the boot and jet as well. So I would have taken them off cleaned them and then, ohh sh!t, I need this too so have to order that and wait for it then pull em apart again to do that.

I do thank you Steve and others for the suggestions and help, as it is greatly appreciated. I think I have found all the sizes I need and have a Fastenal close by that carries alot of Nitiril Buna N orings except if I remember correctly they are mostly 90 durometer instead of 70. I am not sure if that would be too hard of rubber or not but at like $0.12 to $0.50 a piece I may give em a shot or at least go talk to them and see what they say. Its literally like a 100 yards from my work. If anyone know if 90 durometer rubber would be too stiff for this application let me know.

Probably has nothing to do with air leaks, it's simply not getting enough fuel. Most of the time, you will have the screws between 2 and 2 1/2 turns out, but there are differences between bikes.

Thought I would update this as I think I have found my problem(s).

Well this got me thinking that for some reason I was thought the screws should be set at 1.5 to 1.75 turns out, I had mine at 1.5. So I pulled the tank and set the screws at 2.25 turns out and then noticed that the big vent tube that goes from the airbox to what I am guessing is a sort of PCV valve on the valve cover was unhooked yet. Must have been between the lean pilot setting and that huge air leak in the airbox made it turbo lean and wouldnt let it start once warm. Since I have done that I haven't had the problem of it not starting when warm.

I still and gonna replace all the orings since I am sure they are gonna need it anyhow and also want to order a new pilot jet to replace the semi-stripped one. Have to source a decent place for jets yet but will hitting up cycleorings.com here real soon.

So it was lean and that was making it not start..the breather tube had nothing to do with it..it was the fuel mix.
