Guess I Had a Vacuum Leak in the Petcock
Daughters bike has had some minor carburetor issues, flat spots in acceleration and occasionally a pulsing at speed. I had cleaned the carbs a couple times, shimmed the needles, and it seemed much better, but not perfect.
Well a couple days ago the wife says "The smell of gas in the garage is nauseating" I stepped into the garage thinking she was complaining about nothing again and almost started gagging. Looked over at the bikes and there was a puddle about a foot in diameter under my daughters bike. The petcock was leaking with a steady drip, drip, drip. Well I quickly ordered a new petcock, but the daugher wanted to go riding this afternoon. I dug through my parts pile and found a Yamaha Quad petcock. It was a little short, had to mount it backwards, but it worked. Plugged the vacuum line to the petcock since the quad petcock didn't need it. Took her bike for a ride and all the flat spots and pulsing were gone. Contemplating leaving this petcock in place. |

Why wouldn't you? It works and fixes the issue right?

wait a couple days, make sure that yami petcock doesn't have any issues, if not, return that other one and go about life like it never happened.

It does require the daughter to remember to shut off her fuel when done riding.
Also since the yamaha petock is shorter and installed with the switch to the inside it is more difficult to reach. Switching to reserve while riding is not easy. |

Well only you can base the decision on the rider's practices. If it warrents replacing, then... it aint all that expensive.
I feel your pain though, it took me over a year to train my kids to turn off the fuel on some of my other motorized toys. 4wheelers, dirt bikes. Starting a flooded dirt bike after leaving the petcock on for 3 days sucks. Not to mention the extra oil changes. :\

For the next 6 months she is still on her learners permit and has to ride with a licensed rider (ie me) so I should be able to pound it into her head.

I run a raptor petcock on my KLR, no problem! But yeah, a new one is cheap enough and accessible

Install the proper petcock when it arrives, and be done with it.
No reason not to. Don't forget to check yours as well. I assume you ordered Part# 51023? Don't forget to get 92022, you'll need 2. The petcock isn't worth fixing, due to you have to order two separate kits, etc.... Here's my write-up on the subject. Quote:

Have the in line filter. Didn't order the 92022 o-rings, don't recall seeing them when I took the old one off.
Will get them as well. Wish I had checked your link before, thought I had and price was $80. Just checked it again and they are $63 plus shipping Any idea on the difference between the 2 year ranges? Daughters bike is an 89, and pretty sure the tank is original. But my cafe racer will probably need a new one as well and not sure of the lineage of its tank, or which tank I'll end up putting on it. |

They also make petcock rebuild kits, you know. And fwiw, I bent back my spring washer a tiny bit to allow it to spring more, and sprayed my gasket with AT205 overnight and let it sit. It works fine. No issues about a year later.

Other parts places I looked don't list 2 different models, they only list the newer part number. I just ordered the newer one for the café racer. As well as the washers, and bolts, oh and I needed some fairing bolts, oh and some of those grommets, oh and...... $208 later I submit my order.

I would buy a new petcock. The old ones are corroded on the flat disc that is made to seal. The problem is the risk. 100 dollars for a new one. The house will not explode the engine will not fill with fuel. The bike will run normal for a very long time.

Great, The black bike has a new petcock. When I was working on the bike I removed the tank. Went and had lunch. Came back and the heater was sitting on the workbench cooking away. The top of the bench was covered in gasoline. Almost blew up the shop.

As far as fairing hardware goes, I've replaced all of mine with stainless steel allen heads, along with engine covers, and other miscellaneous bolts, and nuts.

I like vacuum petcocks because I don't have to turn them off.

There are advantages and disadvantages to them.
The main advantage, and I'm sure the reason Kawasaki used them on the ninjettes, is like you said, you don't have to turn them off. They cover your butt when you forget. The disadvantage is they are more complicated and when they don't work right they cause other problems. For the average person they are probably a good thing. |
