No, no, this is NOT a problem! It's a feature - the exclusive Triumph
pre-oiling feature. Look at all the wonderful oil pressure you're building
up in your engine as the float bowls fill, and when the engine finally
does start, there is no harsh wear on the bearings and rockers.
And judging from other threads, we should be quite happy that we don't
have to bang on our mechanical fuel pumps with wire wheel hammers
as we cough and sputter on deadly interstate highways...
