124 Crate motor in 2011

Just has the S&S 124 crate motor with 640 EZI cams in it installed. Stock compression at 10.8. I upgraded the TB to a 66mm and put in 5.3 injectors and used the S&S air cleaner setup

Exhaust is a RH True Duals. Rivera Primo clutch and PowerVision

Picked up bike yesterday and unfortunately rained all the way home, even though its summer here in OZ. Only managed to get it to 3500rpm once on the throttle and because it was so wet, just spinning up the tire.

Really pleased at the table top torque curve, but a little surprised at the dip at the start. Reminds me of the Fatcat dip i have had on a couple of bikes before. I may look at using a 2-1 pipe and/or changing to the S&S 625 cams to get the torque to come on earlier.

Blue is 4th Gear
Red is 5th Gear
Green is 6th Gear.

Break in map was supplied by PV..........

It would probably be happier with a 2-1, maybe a 2-1-2 if you want 2 exhaust

That is a rather large TB.

Maybe call S&S and see what they have to say about intake / exhaust before you start changing cams...

Numbers seem a little low to me but I am comparing to other numbers i seen, but max your potential and get a 2 in 1 I am a number hog lol.

66tb is too much imho.. on my 117 I am only going to 56-58 at the most.
