Hello! Long time listener, first time poster. I've got a 1975 xs650 with Mikuni carbs.
I apologize if this question has been answered. I've searched, but I couldn't find it.
I was out on a ride and everything was fine until I started losing power. I stopped on the side of the road and manually actuated the throttle on each carb. The left side is fine and producing plenty of power without the choke lever engaged. When the butterfly valve is actuated on the right side, all it does is produce a sucking sound without power. With the filter pods off, I made sure that the slide is facing the correct direction and slides freely. With the bike running, I covered the air intake with my hand and it shot fuel onto my hand and produced power and white smoke for a short amount of time and then went right back to producing no power.
I pulled the right carb, sprayed down all the parts with carb cleaner (I didn't pull the jets). To the best of my knowledge, it is seated correctly and all of the lines connecting to the other carb are in place. Keep in mind that this happened on a ride and at the beginning, it was running just fine. I'm going to pull off the bowl and see if its full of fuel.
I'm not SUPER familiar with carbs, but Im generally mechanically inclined and open to learning. I'm at a loss and would really appreciate some backup.
Thank you!!
