correct, as in a crank from a XB9 in it, not a 9" throw.

I'm pretty sure you would need to raise the backbone to accomodate a 9" stroke engine. 
I had CrankWorks in Arizona do my work on the above pictured crank. It looks awesome from the pics and all the off-road cranks they have done for me have been spot on. If you need something custom done, they might could do it for you, as long as time is not an issue.

These heads are the best part and someone should cast these up if there are any head specialists out there or knock them out with a CNC. This is a really updated Panhead actually and at 4.0 bore could fit a large range of engines.

Kind of like a Panhead in a way and a path to the much better style valve gear the X-Wedge engine utilizes.
These are very nice head eliminating a lot of parts.

Hey Aaron, I'm putting together a registry for the XBRR bikes. Did you keep your bike? I would love to document it for the registry. Can you share which # of the 56 bikes you have/had, and maybe a couple of pictures? I've got about 20 bikes confirmed with pics and VINs, and another 20 with pictures that are waiting for responses to confirm their VINs. I probably won't find every single one, but I'm hoping to have 50 fully documented in the next few weeks.
Thanks so much,
William |

56 bikes? Does that even make the homologation count?
