I have a 2008 Pagsta or sometime known as a Regal Raptor 250cc Crusa. It will not idle I have had the carbie cleaned by a specialist and it did not do much about the idle. It did gain a bit more speed but that was all. I´ve tried another carbie from a Honda CA Rebel 250cc but it did the same. I´ve changed the o´rings on the manifold because they were hard and brittle. I dont know what to do next can anyone advise me on what to do next. Thanks Paul.
