Anyone have any or could get me some close up pictures of the routing of
the vent lines off of the carb and crankcase on a 73 DT3? I thought I took
some of my bike before I took it apart, but if I did they went missing. Since
posting pics here is a pain, they could be sent to my email. This email address is being protected from spambots. You need JavaScript enabled to view it.

72 DT2, most likely the same...

Picture of a RT3 i had with about 800 original miles on it and it still has all the original vent tubes on. I route all my older Yamaha's this same way. Carb vent lines run forward to the drain hole in the case under where the engine vin number is. The gas if it comes out of the vent tubes just runs out to where the countershaft sprocket is. Parts diagrams shows the tab that holds the vent line in the front bowl screw so thats the way i always ran them? 



 

Thanks for the pics, much appreciated! D
