Yeah.  Pretty much. I think if you use the airbox max scene for location and scale it may be the same id not close. Of course dont rotate.  Do you have quality hpmolgation for kt100?

what kt100? theres a J and and S, the S pulls about 6 more HP, my family runs a kart shop and we have a dyno, we have ran at least 100 dyno runs on a J and many on and S, so i could get some of them for you, only problem is there is a large range of perfomance in them, we could get 2 brand new, never run, put them on and there could be about .4 hp difference

By AKA rules (Australian Karting Association) a good S will have 16-17 hp vs 11-12 hp for a good J, obviously depending on who's dyno it is. The J has a longer stroke, smaller bore and smaller ports.

EVO here is the Dyno. This is with the Yamaha KT100S w/SSX (SSX=4-hole can). Clutch should engage about 8500 to 8600. Max RPM it should pull is 14300-14400. Motors w/ cylinders Y3, Y4 and the 787 are legal (according to WKA's Tech Manuel). Only thing is, this is with the can and not the new pipe that has been added this year. But the can will still do you good, however the new pipe gives that motor that more of a kick. This is the new pipe: the SR-Y Pipe (google image search: karting SR-Y Pipe). I dont have the dyno with the new pipe.

Well by Australian rules, Clubman is the KT100S with MG AZ (red) tyres with lights at 140kg and heavies at 160kg. Clubman light is usually about 0.5-1.0 seconds slower than Junior Max depending on the track.

To answer your question jnl, yes you are allowed to adjust the carb settings. This was just a suggestion of what to run them at. And to anwser your question Andreas, yes, it is the sr yamaha kt100s. it has (w/ the 4 hole can) about 17 1/2horse. I know that the jr rotax is 24 horse
