I just got my bike back from having a full race prep on it. Took it for a ride around the neighborhood and the pig went and boiled over. I called the shop who did the work and they say they didn't change/ touch the coolant. I've heard that changing the radiator cap to a 1.6 will cure boilovers but what's the down side? Also, does Honda make a 1.6 radiator cap? Also, the bike didn't boil over while idling, but ripping around the neighborhood. Would leaning out the carb (Edelbrock) cause a boilover?
