mckenzie Posted February 15, 2009 Share Posted February 15, 2009 Remember that the smaller the bore of the carb, the higher the velocity of air going through it. My dad rekons a 30mm with the right jetting will suffice, but dont take our word (his) do a bit of research, ask around, I'm sure there's a few cab experts out there????? Incidently why is the 170cc kit only giving you 90mph with Stan Stevens tuning? did he also tune the carb?, im guessing not. My standard dt125x will fill the clock nearly (80mph) with 2 up, no joke.... no lie! the only mod i have done is a Dep silencer, earth the powervalve retard wire, and a 18 front sproket!! This is all I've done! Link to comment Share on other sites More sharing options...
