Can't imagine the effects of Lexy getting jealous of a new bike joining the stable.

Ed,

You have to consider that you have a limited area you can remove with the water jackets so that is a limit on how much you can shave the heads.   Why many are only taking 20-25 off the 16/17's with the 117 kits.   On the 117 for instance all things being equal most are seeing 120/126 range add 7 with a typical 1.10 to 1 upgrade on headwork  cubes and you end up 128/134.   is it close yes, but those extra's cost money and all the parts being right.   Not saying it wont happen, just caution in the wind to not get oversold.   Would want to see dynosheets from the same dyno without and with headwork to not see the overall numbers but actual gains.

'Totally Agree,,,
I was thinking more along the lines of Cam, Exhaust, Piston (Dome) and Port Development for the 4 Valve / Dual Plug M8 ,,, not necessarily shaving the Heads... When there are 2 Points of Ignition,,, Domes might become more "friendly"

Looking good on that head pipe.  How is it working?

Best performing M8 dual exit pipe in the industry. I wasn't releasing it until it was.

Thanks Kelly!

Another late night. The 120 is all buttoned up. The 64mm TB looks huge. Almost dyno time!

Should make gobs of power, but at 11.2 CR how are you going to keep that monster cool in mid summer heat?

The M8 is 10.5 comp stock!
I have an OEM fan for the oil cooler ordered. Its a small detail that Harley only put on the Trike and Police models.
Imagine that.

Fired up the 120 last night and got a few pulls in.

Early indications lead me to believe we might just squeek in that 130 squared hurdle today.
Seeing 130 TQ at 3K. lol... There's a few more in it. Lots more tuning today.

Very Nice torque.  That will be a blast to ride, I love motors with great torque like that.

Good looking head pipe also.

That was with 2.0 baffles. Going to test a pair of 1.75s today and see how early I can get the TQ to peak.
Just getting started.

Nice.  This will be interesting to see.  I love good torque down low, makes a bike easy to ride, and lots of fun.  I just love my King and all its low end torque.
