Leaving the petcock on
07/17/17 at 14:17:36

So I bought two more 95's and am in this situation where I have 2 with the petcock change and one stock, so I forget to shut them off sometimes.

Since they are all started daily for different reasons the longest I leave it on is maybe 18 hours. So far the bike starts, but I am wondering what an indicator is that I've done damage by leaving the petcock on too long.

Most people have no ill effects so long as the float and needle do their job, but when they fail, it floods.

I only shut it off to remove the tank... Still, it's not a bad habit to get into... I just don't... Lazy, mostly... forgetful, too... Terrible...

The manual petcock is literally just a little door that lets the fuel out of the tank, gravity does the rest. The actual switch that controls the fuel flow is the float in the carb. As stewmills pointed out, if the float is working properly then it will shut off the fuel, when the fuel in the carb reaches the right height, and it will allow it flow again as the bike uses the fuel from the carb.

If the float malfunctions (it can stick if a bit of debris in the fuel gets caught in around the spring) then the fuel will just keep flowing until it finds its way out of the carb. That's usually out the back into the airbox and out the front into the engine. You'll probably smell the fuel before you see it.

Some guys don't bother turning it off at all. Others, like myself, have got into the habit of switching it off whenever I remove the key.

For peace of mind you can turn the Raptor or other manual petcock off if you wish.
