These are on my project bike. Whats with the hose on the front carb and where does the hose from the airbox vacuum actuator go?
Engine number on this bike is 000118 but looks like carbs and airbox are from a later model?

I think those are from an 83 US model.
Keep it upright and she'll always be happy!

Your carbs are 83 and the hose coming off the side of the front carb should connect to the airbox vacuum actuator. It appears to be misrouted to the fitting on the front of the carb that normally has a hose connected to the atmosphere through a small gray filter.    BDC

Thanks guys, I guess I can use a bit of foam for a filter.

Guess who screwed up, carbs are same as 82 American not 83. Obviously with vacuum actuator modification.     BDC

the hose on the bottom right of the pic (which would, sitting on the bike, be front right) goes to the airbox flapper.  you should have another hose & fitting on the front of the carb that goes to the disk filter.

Thanks Lucky, I now see the disk filter from the 83 carb pic on your CD. It's missing from this bike, does anybody have a spare?

I do, yours for shipping.  do you have the tube on the carb to hook it to? (at the front of the front carb, angled to the right) also the mounting screw is fine thread like the idle adjuster do you need that?
