This article gives some info, not on this specific kit but there won't be much difference between the two.

The article states 1.5 hp at the rear wheel which sounds about right to me. 110cc gives 8.5 hp so 138 cc would give about 10.5 going by very crude calculations. I was thinking about it myself but I decided it's not worth the hassle for only a couple more hp. I think I'd get the bigger kit if I was going to go to the trouble of doing it.

Per the same website, the cam on a 124cc upgrade could net you up to over 9 PS (up over 7.5 PS). So, you're looking at something like 10 PS assuming the gain is linear...

Sounds good...the KSR is an 87kg bike. 10 HP (like .98 HP per PS) would result in a 8.7 kg/HP bike. Compare that with the 169kg 33 HP Ninja 250's 5.12 kg/HP or the 115 kg 17 HP CBR 150's 6.76 kg/HP. You will lose out on the rider's weight, but I'd imagine it would be a really fun stunt bike.
