I've never seen that In the sixties a few riders has an “engine cover” it was a moulding of some description that covered the whole of the right hand side of the engine.I assume it was either light gauge metal or Fibreglass moulding.

LOL Ha, yeah, did they sell double glazing as well? I'd heard that if you continually adjust your clutch cable on the start line and also drop the clutch repeatedly so the bike lurches forwards, you will make blinding starts, nothing to do with anything else. 1 Share this post Link to post Share on other sites

Works even better with a shiny chrome clutch lever 1 Share this post Link to post Share on other sites

It would be simpler to just buy those same handlebars that Bartosz Zmarzlik uses... Then all riders would be as fast as him.. No idea why they all dont do it.... 2 Share this post Link to post Share on other sites

I remember because during that time we painted those Britain's Speedway Riders and ran a league and I recall placing a cover over Ken's engine. Incidently when the 4 valve revolution kicked in those riders who had 4 valves we tended to paint the top of the engine black to differentiate them from those on 2 valves! Memories!
