I just picked up my first bike, 1986 FZ 600. I am new to street bikes but familiar with motorcycles in general since i used to race motocross, this might seem like a stupid question but the fuel on/off switch on my bike i cannot figure which is on and off. I just want to make sure.

Thanks

correct blackhat its a vaccum petcock.kyle there are three positions main fuel tank, pri which is your prime position in case you run out of fuel or dont switch over to reserve in time, and reserve.

pointing up is main fuel middle position prime and pointing down reserve.

push it forward for on and pull it back for of.

Just wanted to resurrect this thread and say thank you! I just got an 86 FZ600 with no owners manual...AND it's my first bike! I downloaded the factory service manual, have the haynes, but none of them say anything about the basics. So what's a newbie to do? Why look on the internet of course!

I have to clarify (in case anyone else stumbles upon this thread in Google search) - the petcock operation is this: Up - Reserve, Sideways - Prime, Down - On

Sounds right" same as my Kwakers,,

I haven't had a fuel tap on a bike for years and, when I did, I used to ride around on reserve all the time (used to love putting my last 32p worth of petrol in so I could make it home!) but I always wondered. What's the 'Prime' for?

Katie, If you take the carbs off for instance and they are empty you can use the PRIME to fill the bowls, it also bypasses the vacuum part of the tap so if you get a choked pipe or no vacuum pipe then you can get home.

Okay, thanks Slice. I used to use the old-style method of taking my bikes apart (throwing them down the road) so would never have needed that but I can see how that would have worked as well

And here's a tip... don't leave it on prime. The person I bought the bike from told me it was the "off" position.... so I kept it there when I wasn't using the bike, came out last week to find a pool of gas on the ground and in my cylinders, and oil.... it wasn't the only cause, but having it in prime allowed the gas to flow freely into the carbs, and the engine, and the oil...

Ah Yes Feliks there's always that, if you don't know ask is the best way but if some numb nut's tells you this is how it works what can you do?

hi! just want to ask if the fz600 is water cooled? against forum rules asking for manuals Thanks!

Nope, it's air cooled. The "rad" on the front is just an oil cooler.
