I own a Yamaha Gladiator SS 2011 model and I am facing problem with idle since a week , when my bike was new it used to idle on 1250 rpm on engine start up since a week i found some difference on my bike idle was not stable on cold when i ride my bike suddenly it changes to 3000 rpm after engine getting warm up . last day i had a talk over with my mechanic and he was having doubt on my Carb so we opened it cleaned only main jet and pilot jet after 30 min of carb cleaning i started riding bike again problem was like same no difference again came to mechanic he removed choke wire & throttle wire and started engine after 10 min to check what was problem
he found idling was rising after engine starts heating up low . started thinking and said to come tomorrow because it was 9:40 p.m so he cannot work on
