Title: Petcock Question
Post by: Chris Baum on March 09, 2014, 03:57:50 PM

COG Nation,

I am wondering if it's time to replace my petcock?  I have notice a little drip of fluid at the end of the on/res/pri switch lately.  What advice does the COG nation have?  I have included a picture of the petcock.

Starting to get the 1986 ready for COG National in June!!

Thanks

Yep it's leaking. Replace or rebuild it. Maybe consider a manual option.

Chris,
I rebuilt my 87 a number of years ago and it's worked fine ever since.  I've only done one rebuild and have had the bike almost 25 years. 

If I had to do it again, I'd think about the converting the stock petcock to a manual, but I'm not sure that would address your leak. 

When mine was leaking, I seem to remember it coming out the weep hole on the back of the petcock but I could be wrong.

If you rebuild it, be advised that the aftermarket K&L brand kits have had problems in the past with undersized O-rings, etc.  Recommend use only genuine Kawasaki kits.  If you want to go manual, check out  http://www.pingelonline.com (http://www.pingelonline.com)  for the best type of manual valve.  Don't faint when you see the price.

If you don't have any visible signs of pitting on the value or seat, I'd rebuild ($13) or I just found a new petcock assembly for $55 (http://www.metricpartsoutlet.com (http://www.metricpartsoutlet.com)).  When the vacuum diaphragm started leaking on mine from the weep hole in the back, I did a rebuild with Kawa parts and went ahead and did the Bergmen conversion to a manual petcock.  This won't eliminate the possibility of it leaking from the diaphragm but I really like the idea of being able to completely shut the gas off.

Murph makes a manual conversion kit that does not use the diaphragm that is a nice job and reasonably priced, see here: http://www.murphskits.com/catalog/product_info.php?products_id=483 (http://www.murphskits.com/catalog/product_info.php?products_id=483)

I made my own conversion years ago which has even less parts and does not use the diaphragm.

Look at this, it fits my '82KZ550A which has the same part # as my '01 concours, its the same part, matched it up and it looks like it will work, don't see why not.
