Title: Petcocks ever changed over the years?
Post by mr.stinker on 05/20/17 at 07:07:45

Sup ya'll

After reading up on the petcock situation I have been wondering if Suzuki ever ended up using a different (improved) stock petcock over the years. I have an '09 S4 and have never experienced any issues with petcock as described in previous posts. Any insight is appreciated

Thank you for this great site

The vacuum operated petcock Will eventually fail.

The same petcock has been used in all years.

There are a lot of things that can affect the durability of the stock petcock. How much ethanol or reformulated fuel is used where you live, if your bike is stored in a climate controlled space (heating and AC) - or is in a shed that can get really hot or cold, or if your bike sits outside, and long your bike will sit in storage when winter comes - and if you add a fuel stabilizer when you put the bike away.......etc.

When the petcock fails...it can create a lot of weird symptoms that sometimes makes you look for electrical or carb problems - when it is actually the petcock causing the problem.

Thanks for the quick responses. Guess I'll go ahead and grab one to keep on hand for when the days comes.

The vacuum petcock from Suzuki is really expensive....we suggest you buy a manually operated petcock from a Yamaha Raptor 660. They are reliable....but you will need to remember to turn it off when your ride is done - and turn it on when your ride is beginning.

Turn petcock on & off? Golly! That's asking a lot....especially for a guy who forgets to use his turn signals. :)

mr.stinker, you need the correct Yamaha part number, don't buy a cheap one off EBAY.

I just went to local Yamaha/Suzuki dealer and purchased the Raptor Petcock - just slightly over $30.00 and took less than 1/2 hour to install.

Just be sure to plug the vacuum line that runs from the carb to the old petcock.

New arrangement is much better and more predictable. I like the old method of shutting off the fuel by myself. !!!
