'80 450E/S Petcock rebuild kits

[Guest]

I was searching around and seems that http://www.crc2onlinecatalog.com/petcock_rebuild.htm
has some kits that look similar to the innards of mine.

There is no 1980 450 kit listed though. Can I assume that only my diaphram is shot and try the one listed for the 1982-83 450s (and many other models)


Strangely mine doesn't seem to have either the large o-ring or the squarish gasket. Should it? If so any idea where they should go? Or should I opt for a kit with the springs (anyone know if the diaphrams similar enough to cross applications?) Could I try finding a stiffer spring instead? This petcock has been a pain in my rear since we bought the bike

Would an inline on/off switch be more trouble than its worth until we can get a good fix on this?

Thanks for any advice! (and yeah I know... get a Pingle :P just trying to get a quick/cheap fix to get her back on the road before winter hits)

They don't make rebuilds kits for the 80 petcock. They try to imagine that it was never produced because it is a pos. I bought an aftermarket K&L petcock off Gerogefix off of Fleabay.

Cool find, but nothing listed for 80 450's. I did a search on Alpha-Sports and they have replaced the 'one-off POS' with the 82 model in their schematics.

I am gonna try something (it can't get any worse) until I can replace it proper. I think I will go the Pingle route eventually though. I will have to add a search on Ebay for one.

Thanks!

Do you have an on and off handle on the petcock?
