I have a 81 Yamaha Maxim 550 street bike. It is a parts bike, I was wondering if I could use anything off it to help convert my 2000 WR 400 to street legal. It is already street legal from the previous owner but has no horn, turn signal, ect. I would like to run a gps and other accessories with DC power. Do you think I can pull anything off the doner bike to accomplish this. I understand you need a rectifier, would the Maxim already have that? Obvously the Maxim is a full street bike with the works so maybe I can make use of some parts from it. What do you all think? Went from a 2 smoke to the WR and LOVE IT, can wait to hit the trails!
