some links to 2 stroke tuning guides & software for you to check out if you havent alredy got them.... they are checked & work ok http://edj.net/2stro...ershandbook.pdf takes a while to load but is ok http://3cyl.com/mrax...graham-bell.pdf bell's bible! slow to load but best if you save a copy then you can scroll at will. http://www.mediafire.com/?w8em1enwwtcwwx8 pretty cool porting software, will work out port heights, spacers etc http://www.mh-aeroto...javapipe_en.htm nifty little java app that will design a basic pipe from known timings. and then print the cone templates for you interesting in itself as you can just look at an off the shelf pipe & instantly know if it will work with your engine http://www.kartingsa...te/Pipe_dsn.zip and another pipe design prog, a bit more detailed this one: hope you find these handy
yeh m8, looks like i'll be modding that leo vinci pipe a bit... to get the rpm i want i need a 46mm header and its only 30mm atm which will restrict it to 8500 rpm. ive got some 48x2 stainless pipe at work so i think ill just get a section of that bent up at one of the sites i go on... save fkin about segmenting it, then ill experiment with the header length til its right
