Turning fuel 'tap' off?

[KEN]

Does it pay to turn the fuel 'tap' off from the Carbs [when storing over winter] or just leave the fuel on. ????:

[unstuck]

Turn it off.:yes:

Leave it on and ride it :scooter:

Makes no difference if it's a vacuum tap.

Tap off to be on the safe side, and full tank to discourage corrosion and fuel degradation.

Awww, that makes me sad. Guess that's the trade-off for all those beautiful alpine roads you lot have.

and fuel degradation.

That'll happen regardless

I thought large volumes of fuel degraded slower? or is that perhaps two stroke mix? Less corrosion is enough of a reason anyway I reckon, poured about a cup full of rust out of my kr-1 tank when the previous owner stored it dry for 6 years :facepalm:

Our shite fuel turns to muck really quickly regardless, but you're on the sprocket regarding corrosion prevention. I drain the pre mix out of my race bikes after every race meet as well. Plastic tank though...

I don't have a fuel tap.

It really depends on the bike ... on older models (pre-1990) it probnably pays to turn them off. In some cases gravity will push pertol passed the needle valve in the carb/s float chambers and flood the intakes if the carbs were angled downwards and the float chamber was not on the bottom of the carb. If an intake valve is open it could flood the cylinders. I have heard (tho' I have no proof of this) that cyclinders have filled with fuel - which has then blown the motor apart as soon as it as started (and someone will give me technical reasons why it's not possible) .. but the idea is a good one. It at least stops the tank drainig through a faulty needle valve ..

I always turned the fuel tap/s off on carbed bikes, when I owned them .. every time I stopped.

Of course, on modern injected motors that doesn't matter ..

+1

Just left my bike for 3 or 4 weeks and it was a bastard to start even over that length of time (starting first go now), can't you take it for a pootle at the weekend now and then?

Ya I start it up and run the motor up to operating temp. about once a month..
