Looking for a working petcock for a cbr600f2 91. My current one leaks now that it is cold out.

 

You can get a OEM rebuild kit. I think its like $40. Complete china petcock on ebay for $20. If it works but just leaks, drill out the rivets, make a new gasket and bolt it back together. Which if you get the rebuild kit you would be drilling out rivets anyhow.
