Are any of the above bikes running an 865cc or are they all 790cc (except PAts bike of course)?
This is the one thing we did not address. I believe pre 2007 the Speedmaster is an 865 cc and the America is 790cc. So Pat's big bore would only give him an extra 39 cc's over a stock Speedmaster while it would give him 114 over the America. It also gives the stock Speedmaster 75 cc's over the America. Definitely something to address as far as hp and torque gains with any mod's.

I think they were all 790s (the non big bore guys).

the big bore is more for compression that cc's, and an added bonus is you get a WAY stornger forged piston

Besides being able to tell the third one down is an 865 because of the year SM you can also easily tell by the numbers. So far it seems to be easier with basic mods to get hp gains with the 790.

Finally some real results showing that even modest changes can equate to some impressive gains. What would be really good though is to know Exactly what mods had been done to each bike as some of these details have been left out? A table for instance comparing all these details would be really valuable to us HP deprived aspirants  .
Then as different mods are made and a dyno done, these results can be added to the table for all to paw over. Just a suggestion but for me these details would be really interesting

That's an excellent idea. Hey Pat, would you consider hosting spreadsheet?
I think this thread needs to 'stick' around for a bit...

Everyone around here wants $100 a pop so my next best is down in south Miami (I have two Dynojet coupons for free runs). Problem is time. I have none. I will get there, I promise.

I wouldn't mind helping out here with updating a spreadsheet or table, in fact I've done a simple one already and scanned it as a Jpeg but it doesn't come out clear enough to read.
Is there any way to upload a file onto this site cos I don't know how?
