petcock issue on '82 650
I recently saw a post on here explaining the petcock positions for fuel flow and realized that i was wrong. i thought that PRI stood for Primary, not Prime and have been running the bike with the switch in that position. I tried recently to switch to the down or 'ON' position and the bike started to hesitate and stall out after a few minutes of running. I'm wondering if this may be a vacuum issue. Any suggestions? Thanks for your timeTags: None

thats exactly what it is. I have the same issue. I just run mine on prime and when not running turn it to the on position. I guess it is fine until rebuild or replace the petcock.

The kits are less than half the price, but are usually junk, and you will have to get another kit or break down and get the petcock anyway.
On the other hand, the petcock will work perfectly, but has to be replaced every 25-30 years, take your pick.

It is a vacume issue. The petcock is vacume operated. No vacume, no fuel. Broken diaphram in petcock, no fuel. The rebuild kits are almost what a new one runs. Most recomend just buying a new one. It's easy to do.

Partshark and cyclepartsnation are a couple of places I've gotten good prices. Partshark wants $58.21 plus shipping for yours. Check around prices do vary and the shipping can be extreme. Maybe not on a petcock.

Good luck with getting it right.

You should have two lines coming off your petcock a larger fuel line and a smaller vacuum line. Is your vacuum line in good shape and connected to your #2 carb?

Once you have the vacuum hose connected to the carb. You should be able to run your petcock on the 'on' position and the 'reserve' position.
Good luck!
