As Soft 02 said, I'm 99% sure it's 4-1/8" Bore for 4-5/8" Stroke -
It's mostly S&S parts.... so their 124" Crankshaft & Cylinders

I know he called it an "evolution" compensatory. With a little google'ing, I came up empty handed....

Evolution makes a 1 piece sprocket in place of the compensator. I finally went with it after I kept tearing up compensators. I was told that the limit for torque on a compensator is 130ft lbs. If you are running more that that, do yourself a favor and go with the Evolution Industries sprocket. The only thing you have to remember is to keep the rpms above 2000. Anything lower, downshift.

Here you go. Not a compensator though. It is a sprocket that eliminates the comp. Page 16 is the 34 tooth and 17 is the 30 tooth. I would go with the 30 tooth...

We went with a stock gear ratio replacement, so I guess the 34 tooth. We have some 75mph speed limits here in TX, and maybe even a couple of 80mph zones near Austin- so 75-80 can be a common cruise control speed - I think that is why he he left the gear ratio alone.
I know I dropped from a 25 tooth to a 21 tooth (I think those are the right numbers) on my EVO , and it really helped it off the line - but hurt on the highway.....

Haven't been on this site much lately and just ran across this thread. I had Wolfgang rework a set of 110 heads and do my cylinders and pistons for a 117 I had in a fatboy. Ended up at 138/132, very fun bike. You'll be happy with your 124.

Honestly, I think I would have been happy with a well built 107 from him..... But he highly recommend a S&S crankshaft- and a 124" build seemed to be the best and for the buck if we were going to split the cases....
Should have some numbers any day now....

Wolfgang says he is going to play with the tuning more tomorrow, but the bike hit 136 HPtoday on the Dyno!!!!!
He usually uses a TTS, but I already had the PowerVision so he is playing with it.
