Picked up a 1980 650 a few days ago and it looks like everything is here for me to fire it up. I wanna get it running to see if there is anything wrong in the bottom end. Before I pull and tear down the engine. my question is from carb to head intake has a inlet on each the right side has cap on it the left has a hose with a screw in the end. Is that supposed to have a cap also?
If I understand correctly those inlets are used to connect a sync tool. Finally on the petcock their is a connection with no hose to carb. IS this the reserve its something I haven't seen anything like this on any of my dirt or street bikes ever. This is my second yamaha back about 12 years at least I had a rd 350 2 stroke streetbike and it seems like I remember only one outlet for that also. Anyways great forum and thanks in advance.
