If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

Petcock issue.

I have been working on a 1981 GS450L and after rebuilding the carbs the thing was still acting like it wasn't getting proper fuel/air flow.

Come to find out my new problem with the petcock.

Now, the petcock that was installed on it last looks like a universal petcock; in fact, the previous mechanic hammered a dent in one of the tubes in order to get the tank to sit on the bike with this aftermarket thing on it.

I was wondering whether it was worth it to order a new $89 petcock that is FOR this make/model or if another universal that costs like $20 be worth the savings.

After disassembling and reassembling the petcock, the bike seemed to almost work but still randomly craps out; I assume to lack of fuel flow due to the PRI position not working properly.

Note:

I rebuilt the carbs because once I took them apart to inspect them I realized that most of the parts didn't match each other; it was a mess.

Buy a new OEM petcock, might have a carb problem as well. Not sure how you can use unmatching parts in a carb?
 
New OEM petcock. Tried a couple different knockoffs and they all leak. Rebuild kits leak. New OEM unit is perfect.
 
Thanks guys.

I don't know how he used mismatching parts either.

The thing ran but would rev up to full-throttle as soon as you started it; told me it needed a little carb work.

Replaced almost all the parts in it as a consequence.
 
Pingel is an option as well, mine cured mystery jetting problems, just saying....
