How big is BIG

Looking to do some engine work to the CVO RK 2014. Would like to see what others have come up with, and what works and what doesn't .
Looking at or near 130hp has anyone gone there.

I've found one in Lebannon, MO at 180 hp but the picture shows some l
kind of aftermarket SC or Turbo, not what I would want.

Looking at Cam, pistons, bore ect

Thanks

Here's a thread that would be worth looking through if you haven't already. Gives you a good idea of what others have done and what to expect out of different combos.

For 130 hp though you'll probably need to do a little case boring.

Pair that with a Trask and it'll have all the power you'll ever need.

More effective to match the torque curve to your riding style than to chase numbers out of your rpm range.

Fellow forum member Target64's 107" pulls 129 hp, for example.

117 would be my pick too, but a 143 may be cheaper if ya can sell your motor.

The 110" cases will not accommodate the 4.125" cylinders; case boring is required. The OP should cut to the chase and spend a bit more money for the S&S 124" motor; the touring version would provide all the performance the OP could handle.

exactly cut to the chase with S&S 124 -- if you feel you need more - the S&S motor can take a lot of upgrades without sacrificing reliability
