0:05 i could only imagine that a 3 yr. old Lad observing the mad dance of the intake and exhaust spring's quick time in place, looking like a pair of metal soldiers coming alive and motivating the rear wheel. But i'd been up all night viewing old British bikes. i'd best take a nap before riding my 68 Trophy Sports this morning. -gilpin 10-13-16
I can’t say for certain, but nearly all veteran motorcycles had a total loss oil system. This means there was a single oil pump that pumped oil from the tank into the timing chest, which then made it’s way into the crank cases, and was then blown out of the breather after lubricating the crank assembly and bore. Top end lubrication in side valves was done via the oil being pumped up to lubricate the pushrods via galleries from the timing chest. OHV engines required external lubrication prior to starting due to the valve train being exposed. This is speaking in general terms, there were some exceptions to the rule.
