New Issue...

Hello All

Recently I had an issue with my carb which the members on here helped me narrow down. Well after getting my bike running and after a test drive I came back home parked it and this morning there was a gas leak. So it seems at the tank on the petcock the little clamps are on all the hoses correctly and the hoses are in good condition yet the main hose that goes from the petcock to the carb just streams out gas where it connects to the petcock. It is almost as if the tube is bleeding out gas...

Has anyone had this issue? Could it just be that the tube is old and needs to be replaced or am I looking at a diaphragm issue in the petcock?

Your petcock is shot, save your time, and money and get a new one, the cost of rebuilding it isn't much cheaper, due to you need two separate kits, as they for some reason don't make just one.

New one cocost about $65.00

http://www.partzilla.com/parts/detai...1023-1139.html

Also be sure to order the orings and new bolts, trust me you'll be better off in the long run.

Rebuilding kits are about $60 total.

IMHO not worth it rebuilding, also be sure to check vacuum and fuel lines for wear, holes, and cracks, if in doubt replace them.

Does this happen for any position of the handle?

You could try tightening the two little screws on the flat washer around the handle.

If you wrap toilet paper around the petcock and hose, you will be able to see the source of the leak.

True, but I'm figuring the age of the petcock, I'm better it's just wore out being 19 years old

Does your bike still have the stock, wire hose clamps?

I had a similar leak, same fuel line. I thought I was going to need to replace the petcock also but I pulled the stock wire clamps and replaced them with a regular hose clamp and that stopped the leak. For a couple bucks, its worth a check.


First post.....guess I should make my way over to the intro section and stop lurking
