i think im in trouble now, im getting rid of my V65 Honda sabre and honda GL1000, I dont have the time, Nor the Ambition to work on them (the GL is rotted anyway) how ever, since seeing that Turbo GS i have been keeping an Eye out for source parts and think i found one. I have a 82 Yamaha Maxim XJ650, #2 intake valve is hurting, and 2nd gear is hurt, I Just Found a Seca 650 Turbo for parts for it, but im Torn. you cant really see that Turbo on the seca and my Maxim has the same engine, this would make for a nice sleeper on my Ratty Maxim. but, figure 650cc isnt awhole lot More Volume wise then the 500 so the Turbo should work well for it. hmmm so far i think i have seen pix from 2 turboed GS's, one had an Airbox around the carbs, and the other didnt, just a Plenum Box and metelstraps over the carb tops. But, the Maxim is a straight Bolt in from the seca ARRRRRRGGGGG!
