Today I replaced my petcock with the mikes xs non vacuum one. I also replaced my old floats with new ones (brass @ 26mm) the bike starts fine and seems to idle fine. Then I rode it around the block and at stops it was revving at 3-4k. I lowered the idle speed screw and it was idling fine at ~1300-1400. I turned it off and went inside for a minute. Came back out and started up fine but now it dies after idling for a minute. What would cause this? Mix screws are at 2 3/4, fresh gas. To plug the carb boot I ran the line that used to go to the petcock to the other carb boot since I had no other plug... Could that cause this?
