I got in touch with the seller of the MZ/KTM some while ago to ask him about his carb mods, this was his reply -
"The new carb is for the Yamaha Raptor/Grizzly 660. It fits the existing inlet/outlet rubbers. The mixture was set using a lambda sensor to get the jetting/needle position right. The original carb + cables come with the bike, so it could easily be returned to standard. I found the old carb hard to setup, or rather, once set it would 'drift' over time and need resetting. The new carb might not give as much top-end, but that wasn't a problem for me"
