its really funny that you say "super high revving"....no 2stroke of 60/65cc revs even as high as the modern 4sroke engines of the 250/450mx and 600/900+ of sportbike designs. the bigger the 2smoke piston, the slower the max rpm.
the 250smoker the OP has only goes to 9k.....yet my 250f (4stroke) still has another 1300 rpm to go before it hits max hp.
Ummm I've raced the KT100 Yamaha 2 strokes in open karts that spin 14,500 every lap. I can assure you there are tow strokes larger than 60cc spinning way higher than your 4 stroke ever will.
