You guys.

Looking forward to seeing the final products. And the final dyno numbers.

What will the bore/stroke dimensions be?

Imagine the torque! No need for a desmoquattro, certainly not as a street bike.

Well done.

Any headwork, how to mod ign/fuel?

The stroke will be unchanged.  I'm pretty sure the stock stroke is 71.5mm.  The bore will be changed from a stock 94mm to 100mm.  Here is what the pistons look like.

There will be head porting and a multi angle valve job.  The ignition and fuel will be taken care of by the stock fuel injection along with the Power Commander III that is already on the bike.  Donnie Unger will Dyno tune the bike and dial it in.

I'm not sure exactly.  I'd imagine it will be a couple of weeks.  Just got word today that my cylinders were being bored.  So things are moving along.   [thumbsup]

You know I check this thread every day..  [popcorn]
I know it will be done by spring, probably a lot earlier.  I'll post as soon as anything happens.  Try checking once a week.

Desmosedici - it's the new Paso (except the bodywork doesn't fit as well)

Head Work with minor porting and polishing is now done.  Four angle valve job has been done.  There is not enough resolution in this picture, but you can see all four angles up close.  The finished head is on the right.  The valves now sit up higher on their valve seat. 



Not a very good picture, but you can see everything is shiny & smooth.


In this picture you can see the intake tract.  It is fairly straight for good flow.  (I got to see a bare Desmoquattro head while at the shop.  Now those intake pathways were arrow straight.  That is a big part of the reason they are able to make so much more horsepower.) 


The exhaust exit is fairly straight too.


Front and rear heads sitting side by side.



I'm pretty sure we will get the bored and re-plated cylinders back fairly soon.  Probably sometime this week.  Pistal pistons are on their way from Italy right now.  Hopefully they will arrive soon too.

They look fantastic. I'd like to see some hi-res if you got 'em.
