I forgot to mention that there were 4 or 5 Triples at the race. They are 750cc, 3 cylinder 2-stroke engines that were originally mounted in a Street Bike Chasis. They were called H2's and were produced in the 70's. Imagine having three 250 motors on one bike. They had three carbs to jet, (strangely enough with no reeds) three plugs to change and three exhaust pipes. The original pipes of course are a no-go. That along with modifying a 250 chasis, makes for some really neat custom fabrication. There are some other one off bikes on these vids, they all rode in the 750 class that I had footage of. There is also an Open Class with more custom bikes, but have nothing to show you from that Class.
