Possible petcock fix?

[OriginalOwner]

It works perfect!! By removing the little stop tab so the lever can be straight up I have OFF. By removing the diaphragm o-ring I have ON (without needing vacuum) and still have a functioning RESERVE when in the RESERVE position. PRIME is no longer needed since vacuum is not connected. The filter screen is connected. I also added an inline filter to keep the fine rust dust from the carbs. I did leave the diaphragm spring out but you can do what you want.

You King> you didn't happen to take any pics, did you?

I need to do this to my '81. I've owned this bike for 39 years and NEVER liked the vacuum setup. I've never rebuilt or replaced the diagram either, so it sounds like an accident waiting to happen. Could be my imagination too but it seems like, right now, the bike starts easier on PRime position.

I did have to cut a little off the lever to clear the tank. That made it a little harder to switch positions.

I wanna do this but I need some help. Do you have any pictures?

What don't you like about it?

It is a model of basic simplicity. Start the bike, fuel flows. Turn the bike off, fuel stops.

If you don't ride for a few weeks, you do have to prime, but you would have to turn on a manual petcock anyway.
