Lee :If your question was directed to me we can measure the 3 mounting points (cylinder head , rear upper, rear lower) in the 3 dimensions within +/- .001" per foot of the engine being measured. Of...

If someone can get us empty cases we could do an atocadr14 or 2000 version for no charge

I think the best AMA 1000cc supebike time is 2:13 (2006)with the chicane, which added around 8 secs from the year prior(2002)? subtract those 8 secs leaves about a 2:05 without the chicane...
