LOL! Happens real easy don't it. I got a feeling you'll like them tw-8-6 cams better...the 7's are great, but the 8's will benefit better from your headwork & higher compression (carry out a little more) while still makin a solid botom. They are very simillar to my t-man 590's.
Looks nice, I used to play with Volkswagens years ago. A little porting, new valves, performance cam, could get you 15-25 more HP easily.
When my warranty runs out may play around with the bike a little. Thinking a higher volume oil pump and rigging a Jagg cooler with a thermostatic controlled fan. South Korea can get hot coupled with stop and go traffic, it's and oil killer. I change it every other month in the hot season.

I go back and forth on going 103ci while I pull my heads or staying 96ci, I can't make up my mind. I don't want my cylinder walls too thin or too high compression with this FL. heat. I'm shooting for mid 9's and it looks like that can be had like you just did. What pipe did you go with?

Intake
Exhaust
The majority of the porting takes place on the intake side. HD restricts the intake port possibly for EPA reasons. The exhaust port is fairly large to begin with and it just gets cleaned up. It's not a big size port you want, what you want is the best velocity. Bigger is not always better in this case. Don

I'm sure you already know this,but I read an article on one of the performance webs sites which showed how the factory header gaskets sometimes compressed into the exhaust port negating some of the flow that you spent so much money trying to achieve. It showed an aftermarket gasket that was a little trickier to install but would prevent the gasket from bulging into exhaust flow. I wish I could find the link,know I saved it but can't find it now.
Good Luck
