Close or leave open?

Before I bought my V Star 650 Classic, I took the MSF basic riding course. I'm sure it was money well spent, having not been on a motorcycle for some 30 years. One point they harped on about was closing the fuel cock on shutting down. I find I forget about 50% of the time, but so far have seen no I'll effects from doing so.

So my question is, does it matter? Will fuel seep into the cylinders? Or is it just a good habit to get into?

Thanks for any guidance.

It's a good idea to shut it off. If you're only going to be stopped for a few minutes, it doesn't really matter but if you are going to be parked for a while, shut it off. It's possible for a float valve in the carb to stick open and if the petcock is on, gas could flood out the cylinders. Or you could develop a minor fuel leak that could drain the tank if the petcock is on. With that said, the only time I ever shut off the petcock on my last bike was when pulling the gas tank or changing a fuel filter. I never did have any problems leaving it on all the time.

Agreed that it's a good habit to get into, but also agree that the last bike I had with a carburetor, I never shut off the petcock and never had a problem in over 10 years of riding the bike.

Ok, this sounds like what I expected. I'll try to get into the habit of closing the petcock, but won't lose any sleep if I forgot.

Thanks for the helpful responses.

I only shut the petcock off when I know I won't be riding for several days or more. The rest of the time I leave it on. I've also not had any problems in the last two years but ymmv of course...lol.

The other side of that is remembering to shut off the petcock, then coming back to the bike hours later, and getting frustrated that the bike keeps dying while you are warming it up, only to blush deeply when you finally remember to turn the gas back on.

When I've started it with the petcock closed, there's a metalic clicking sound (electric fuel pump?) that stops when I open the valve. But I have once had it begin to sputter a minute or two after taking off! It only took a second to realize what was wrong.

I have a vstar 650, I NEVER turn the fuel cock off. NEVER had any issues but then again all v stars have a fuel pump so there is no need to turn off the fuel cock in the first place. Just my $0.02.


thanks,

I was pretty sure that clicking sound was a fuel pump. Thanks for confirming it. And I did wonder if having a fuel pump would negate the value of the stopcock. Many thanks for your reply.
