I have an 05 250ec, totally standard. Would like a bit more bottom end. The bike is used for tight techincial trail riding. Which pipe would give the strongest bottom end, top end not important. Also has anyone fitted a flywheel weight or one of those aftermarket powervalve covers.
Any advice...
I have a 2005 ec250. Main jet 178, pilot 38, needle type N1EF clip positioned in centre. The bike runs runs well but rich and can fowl plugs. The bike is used only for trail riding so mostly on less than half throttle. Any advise would be welcome.
