KyleM Posted September 15, 2010 Share Posted September 15, 2010 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 KyleM Link to comment Share on other sites More sharing options...

feliks Posted September 24, 2013 Share Posted September 24, 2013 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!

feliks Posted October 15, 2013 Share Posted October 15, 2013 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 1 Link to comment Share on other sites More sharing options...

Katie1 Posted October 17, 2013 Share Posted October 17, 2013 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? Link to comment Share on other sites More sharing options...
slice Posted October 17, 2013 Share Posted October 17, 2013 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.

Katie1 Posted October 18, 2013 Share Posted October 18, 2013 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 Link to comment Share on other sites More sharing options...
feliks Posted October 20, 2013 Share Posted October 20, 2013 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...

slice Posted October 20, 2013 Share Posted October 20, 2013 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? Link to comment Share on other sites More sharing options...
deografx Posted October 29, 2013 Share Posted October 29, 2013 (edited) hi! just want to ask if the fz600 is water cooled? against forum rules asking for manuals Thanks! Edited October 29, 2013 by drewpy Link to comment Share on other sites More sharing options...
feliks Posted November 11, 2013 Share Posted November 11, 2013 Nope, it's air cooled. The "rad" on the front is just an oil cooler. Link to comment Share on other sites More sharing options...
