well i did modified that novarossi 3sct, i changed the timing on the crack to 65° ATDC and made those "fancy fangs" on the sleeve, and also poslish the fang on the cranck. this engine on track was a bullet, smooth, tons of low end, great middle and also impresive high, very consistent, great power, literally was a bullet. and the best things of all, great millage. 6 min no problem.
i'm pretty greatful with this tread with the help of Stefan and Roelof, both were great help. thanks
