I found these pictures this morning on the perthstreetbikes.com forum. All I know about them is what was in the description on the thread. The builder is a guy named Frostie from Lund Sweden. He says the injector bodies are two out of three from a Triumph 955 with an inside diameter of 43mm. He's planning on using a MicroSquirt injection controller box from MegaSquirt because it includes a programmable ignition system as well. He did the fab work and built the cross over boost tube with angled riser blocks to help direct intake flow to the bottom end.
All I have to say is I really need one of these setups! Its a shame that Yamaha didn't come up with something like this back in 1985, we might have still had factory built road going two-stroke replica racers well into the 90's here in the USA.
I hear ya Travis! Oh what might have been!
