Agree with this. 103 to 107 might not be enough for you, so that new flywheel option could be the direction you're looking for. I would go with a new S&S flywheel and go from there, go 124 and don't look back!!

Ride safe!!

You seem to never be content with your bike , sometimes throwing money won’t scratch your itch might want to consider another bike for what you are looking for

As much displacement as your wallet can handle and then there’s NOS, Turbo, Supercharged??

Then the primary and gear box need to be fitted with all the good stuff to handle a 200/200 build.

.... Then the guy with a BUSA blow you away anyway??

I would laugh at you for wanting to make your Harley fast but I got the same sickness.

I know your all the way up in Illinois but give Brandon at J&B Performance a call,look them up on FB, he will steer you in the right direction. Another choice is call Jamie at Fuel Moto, either one will build the power you want.

Sometimes this is the answer. I'm trolling craigslist and facebook looking for a track bike again. Love my Harley, I'll never be without one but spending the amount of money it takes to make a Harley "fast for a Harley" still won't really scratch the itch when I've had 8 second street bikes with perfect manners before. I decided it was cheaper to buy another set of leathers and a second bike to scratch the itch.
