Assuming you can use 2 strokes at your track..... why not fit something like this:-

You'll be lucky if you get as high as 10bhp from the GX160.... that motor will give closer to 30 for (currently) £105....
For precision:-
1) I am NOT knocking 4 strokes or the Honda in general 2) I, too, like tinkering and improving motors 3) however, if you want to get POWER for no money..... there's no contest... air-cooled 2 strokes win EVERY time! (except the AIXRO of course....)
