help. i have a leave on the valve under the tank that the reserve tank handle is attached to. btw it is a 92 cbr 600 f2. it leaks out of what appears to be a nipple directly on the bottom of the valve. it only leaks while the bike is running. thanks for the help. david

 

sorry i didnt ask my question. what would cause this and what should i do to fix it?

 

could be a bad valve. you can replace the petcock and see if that solves your problem.
btw the only different between the "normal" and "reserve" is the height at which the tube is able to pull fuel from. they are both right next to each other just one sits up here - and the other sits _ so you could actually fill your tank and leave it on reserve and gain more before you had to fill up again but this is dangerous cause you will not have a "reserve" to save your *** till you get to the next gas station

 

i have a brand new petcock. forgot what it paid for it but it was for my f2. i'll sell it to you cause it's just sitting there.

 

j-dubb how much for the petcock?
