Just finished installing the TFI unit on my scoot. All I can say is wow!!! She runs like a different bike. Much better throttle response. Haven't ridden any distance yet to see if it cools off the engine but it definately runs better. on the install, I actually removed my gas tank and ran the wires thru the harness and down to the TFI which i installed under my left side cover. fits good. i used the setting included with the TFI for a stock bike. insalled the unit, set the pots, fired her up and rode..couldn;t have been easier. Now I gotta put those SEII on again. Hope I dont have any waranty issues!
