You wouldn´t by any chance know much about the carb. or how to adjust it. My problem is I can run to for awhile and then when it heats up it starts to choke itself out. and i have to keep reving the engine to keep it going. by the way the idle has to be set higher then I like to keep it running also. but as soon as i shut it off or it does choke itself out. I cannot restart it unless I let it sit for like 10 min. Do you have any idea what that might be or how to make the right adjustments to fix the problem?? any info would be great. one other thing, at bikebandit.com the after market sproket i think the star.. something brand will this work with the bike????
