you mean delphi EFI; yes thats the same in Road Prince and CSC and I think thats the only thing that matters alot...
1 - Well the CSC had a different front lamp
2 - Had a different Body Decals
3 - RoadPrince bike had now zongshen written on it probably they removed it them self, event ht parts like handle bars and few other places have "emobossed/grooving of zongshen which was missing in road Prince.
4 - On whole bike there was no 250cc logo or any 250cc marking, even on the cylender block where usually 249cc is groved that place was empty/ shaved as well... so in short there was no way to track back which revision number the bike was pointed too...
But again dont just take my observations as any verdict may be they just removed evidnece to save taes for us people ?
becuase over all the Bike is Jambo Jet from road prince..
