Bought this on the last day of the R.I.P.P.P.P.P.P Rally in Chicago. Already had a 50cc Airsal kit and 15.15 Sha. Opened up the stock intake to 15mm to match the carb also matched the transfers to the Airsal kit and welded a vlx header to a Morini Mamba pipe. Extended the pull of the throttle to open the 15mm carb. Also running Sava MC2 16x2.25" tires.
