By the way, why would you need to bump to 110ci just for 100hp? Get some headwork done and some different cams and you should be able to get 100hp with a 96. There are a few guys on here that have gotten close to or over 100 hp with an 88 even (not many but I've seen a couple).

Anyone know if it'd be possible to shoehorn this motor into my FLHR? I figure that with 190hp and all-day comfort, my bike would truly be king of the road.

It will be easier to get 100+hp out of 110 inches than fit a 'Busa to a dresser!

A pair of 'Busas do hold the current land speed record though....

Sounds like you need a hot rod goldwing.
