When I was measuring the squish and compression off the head off my ktm125 sx '02 I noticed a very wide squish(55%) and a clearance off 1mm,but the compression seems to be not so high(valves open 7.9:1 valves closed 10.5:1).Now I want my bike to run very strong in the midrange so I was thinking off raising the compression because it is not so high,but the msv is problably already high because its wide squish band,so would this be wise if I am planning to stay with pump gas?And what affect has a bath tub design vs. a hemi sphere chamber on the power band?thanks!
