Throttle Body Change
« on: June 24, 2016, 11:29:47 PM »
Y & M: 2014 TK Twin Cooled 103

Mods: Displacement bump to 107. heads ported, 1.9 exhaust. OE compression. Cycle Rama 575 cam. Ness stage 1 with Rushmore cover, FullSac DX, 2.0 CVO cores with screens. On this mild build would it be beneficial adding 58mm TB? Not wanting to give up lower speed throttle smoothness.

Thanks in advance

Thanks, Don

I was leaning towords keeping the 50. Wasn't confident the money spent would be worth it.

I added the 58mm to my 103 along with the Harley SE CNC heads, it really made a difference

attached chart, this is the only one I have but even without seeing the chart the difference is huge, my other bike is a 127" softail so I'm used to the power, this 103 impresses me.

Couldn't hold the monitor sideways long enough to view it.  :)

Something very awry at the start of that pull.
