The best thing i've used to date is a chic's hair tie thing.. lol. Its like a rubber band, but really thick and elastic not rubber tho.. Tied that around, it holds the choke off for riding and when I need the choke, just pull it back and hold it.. once ya done let it go and it holds it closed. I've tried rubber bands but those get hot and break. I will be pulling that little rivet out of the bottom of my pulsa-jet soon and replacing it w/ a rounded end screw so I can use the choke like stock again.. i'll let ya know how that goes.
