Hi bud, im down the road in leeds if you want me to have a listen to it? i can get over saturday morning if any good to ya.
you are right as you say, on cold everything is dry and free of oil so will need a couple of seconds on start up to get oil around chains, cams etc.
i tend not to touch the throttle pedal for at least 5 seconds after any start up to to get everything lubed up.
