idling on choke

[catbed]

i am numbering the cylinders right and i dont think the petcock is leaking because i got it new in october. the number 2 header gets hot after the bike runs for a bit.

Great to hear it's running better. I still think that your #2 pilot circuit needs further investigation!!
Have a Happy New Year.

i cleaned the pilot circuit again but it still doesnt fire right away. after it warms up for a bit, if i adjust the mixture screw for number 2 the idle speed moves with the screw. i cant find my compression checker right now, but once i get it registered, ill ride it to a mechanic and see if he can tune the mixture and check the compression. its been ridden for 8k miles so could the valves have worn that much?

i doubt the the valves would go off after that milage to cause a major problem provided they had been correctly adjusted (so, yes, you do need to check them)
check the compression and if nr 2 is a lot lower then the other cylinders that'd be a good indication of where your problem is

actually, just remembred, i had the exact same problem with one of my bikes, where one cylinder would fire properly only with the engine warmed - it turned out to be a burnt valve

just got a new compression checker and all of the cylinders are at about 145 psi. well except number 3 which doesnt have any. i was greeted by knocking when i tried to start and ticking when idling. its a stuck valve. now i have a better excuse to do a valve check.

would a burnt valve have compression?

would a burnt valve have compression?

nope
i'm afraid it sound like it's time to take the head off

i was talking about the #2 cylinder, so it doesnt have a burnt valve. the number 3 cylinder im 99 percent sure it has a stuck valve. im goin to take the valve cover off and check the clearances.
