The record at Bonneville we are after is 124mph in the 650cc m/vintage fuel class and 127mph in the m/vintage gas class. We already went 123mph in 2012 so we are pretty close but its always the remaining few miles which are the most challenging ones. We hope these new parts will make us go faster.

Last year we used the aftermarket nos pistons 11-1 cr with the high dome (left side) but then i have found these original hepolites with the lower dome. I think the high dome creates some kind of turbulance and hinders efficient flame travel. It seems like the hepolites are close to 11-1 cr too, but they have a lower dome which will help with the flame travel.

| Any info on these pistons? The # is E2931 |
 |
| Found a pair of late 60's beefy rods, the one on the left is a p/u con-rod and is much lighter but not as strong |
 |
| Found these vintage Harman & Collins cams they will be the brain of our race bike. |
 |
| And last but not least a beautiful iron cylinder head back from the stripper ready for rebuild. |
