I know, why bother... fact is over here (Switzerland) my BGM big bore will not get through the MFK (MOT), so need to use a standard pipe (also just learnt if found with non std pipe by plod then heavy roadside fine also common practice).
I have an RT195, with a BGM manifold, 28 mm delly and ramair filer at present...anyone any idea what carb set up i would need to fit for a std casa exhaust..hoping it will still pull 60-65 mph ish with the new set up ..a crying shame as it is a blast as it is.
Will look to put BGM Box back on for the euro and ventures across the border so likely invest in a new carb for the std exhaust/when using at home..gut feel is 26 mm delly (vs having to swap manifold out and go sh20/22 route)
Thanks
