Gave the Hornet a service yesterday. Oil, filters, plugs, clean and relube chain, cables etc... I've noticed the Hornet has been idling more erratic, esp when cold, lately. Now there seems to be running a little rich and has developed a slight engine flutter. In my exp with engines, I'd say either the carbs need looking at/synch, or the valve clearnces need resetting ( smell of unburnt fuel at exhaust with a slight 'coolness' is felt every few cycles ). Unfortunately there are no service manuals ( in english ) for the hornet. I am assuming the power plant is the same as the CBR250RR, which means the valve clearances are set by shims. ( not sure if most bikes do these days .. I am not a motorcycle mechanic ). If this is correct, then I should set clearances as per a CBR .. right? :? Can anyone shed a little light here ? Not sure how difficult a job it's gonna be, easy enough to do a DOHC out of a car, on the bench .. but bikes ???
