No offense, there are those that will always quest for more power,
My 124 softail makes plenty, doesn't need anything else other than the 9bG woods
cams that helped it over the softer street SNS 640's which were no slackers etiher.
Have a friend with an out of the box 120R no work and it's spinning a Rivera Pro clutch with the gold racing spring...
Cleaning up the heads will help no doubt but at what hp per dollar cost are you getting
with the money for the Tman cams and head work, at some point the increase HP per dollar spent declines rapidly, been there done that and at some point you are just chasing dyno numbers...
Ported Heads $700
107 Kit Pistons/Cly $800
New Intake HPI $500
Weld Crank and timken $100
labor to do engine $500 to $600
Misc gaskets fluids $100
Right there you are at $3050 over half the cost of a 120R at retail
and not anywhere near the base of the 120R, and you'll never get near
Anyone out there would be better served if they are HP junkies to drop
in the 120R and forgo having a shop setp a performance engine other than
a basic head port and cams, any work over $2000 to bump the engine
will be thrown out at the next change, been there done that, it's why
there is a 124 in the softail...
I think though when I do the 120R I will stick the stock engine in the box, lube and seal it up, so when I sell the 09, I'll pull the 124, drop the stock engine back in, and put the 120R in the next bike....LOL
