The engines you speak of here are Briggs reproduction " CLONED " engines and for the most part.
They also run on Methanol and run extremely hot, it would last maybe twice around the block if put on a bike as it is run on the Jr. Dragsters.
but if it were toned down a bit and put on gasoline with a good overall set up oh..........! Yeah...........! it would take one heck of a bike to handle one of those custom " Briggs design cloned
" Blockzilla engines, they are wicked fast, but only actually run that good if set up on Methanol and a big cam grind with larger valves and very high compression and advanced ignition timing.
amazing how they push that liitle rail at 80+MPH
