xj550 turbo?

http://classic-motorbikes.net/wp/yamaha-dresda-xj550-turbo/
was looking online and came across this? any thoughts? they put an oil line into the bottom case?

 

oh and single carb?

 

There is some interesting, and some questionable, information in that article.

I like the frame. I would have been interested to know what mods he made to safely (I assume) raise the red line to 10500. I am skeptical that the ignition has been changed to CDI or that the heads have been modified to turn it into a 16 valve motor as this article reports.

 

Ignition change isn't hard, there's any number of kits and I know at least one person who made their own, as for the head they've just got that wrong, I have the original magazine somewhere with that article in it

 

so i was thinking of turboing my yx600 motor but i would have to get difrent carbs but it lookes like the made it so that the turbo is inbetween the hed and the carbs so you dont need a special carb?

 

True, but it's much more common that people assume any pointless ignition system is CDI. I think it's much more likely that it's still TCI, although, depending on whether they're getting enough fuel under load, they may have changed the controller for it to a programmable one, so they could retard the timing a bit and help prevent detonation.

I'm using Hitachi coils off a Saturn on mine, and Microsquirt driving them... but it's still regular TCI-type dwell ignition, not CDI.
