    I called Kevin (Motorcycle Recovery Specialists). Great guy he got me and the bike home definitely recommended. Turns out it was probably low gas and possibly a fuel blockage from riding around in all the hills. I drained the tank, what came out seemed clean. Got a new fuel filter and changed the plugs while I was at it. Rode around the block a couple of times last night and it seems fine now.

    Crap I completely forgot about the air filter. Will change that soon, the guy before me did stuff all maintenance. I had the oil and filter changed when I first got the bike.
    Check the vacuum valve itself. It may get shit in it. Either wont open or wont close. If the same thing happens again, set the tap (if there is one) to prime. This will open the vacuum valve manually. It may help.

    Actually now you say that, Kevin turned the fuel tap and that's what originally got it started.... eventually. Seemed to be okay today although I didn't ride far, maybe 25 odd km's. It still seems to be still getting fuel when turned upwards at 12 o'clock position which should be fuel cut off, which is strange. 9 o'clock means on I presume and so 6 o'clock (pointing down) Must mean prime or is it the other way around?

    I'm laughing that's actually a pretty funny mistake and here I was thinking something serious had gone wrong. Glad I changed the plugs they were filthy! The fuel filter wasn't bad didn't see anything come out of it. Next time if I want to venture into the hills it's gonna need more than 1/4 of a tank.

    Is I recall ... most vacuum taps do (may) not have an "off" ... as the "vacuum" means it shouldn't allow fuel to flow with the engine off. Some bikes may not even have any tap they can alter the position. (mine is one)

    The main part of the tap down should usually be "on/run" ... with it up to "prime" (refer to owners manual to confirm)

    Or ... in hindsight .. it may be a reserve. (and prime)

    Next time you find yourself with nothing to do ... (with a near empty tank) pull the lines off the tap and test this theory. The vacuum valve will open with a line from the tap to your mouth. (takes bugger all)

    Some (like my VT250) have an off instead of a prime, bit annoying when you just want to drain a bit of fuel out for the mower...

    All the taps I've seen have it written on them what the positions are for.

    That would be going on the assumption it is the original un-barstardised tap ... owners manual or workshop manual (or google) may confirm.

    Well the tap and vacuum valve are the same part, so the prime or off tags will still apply.

    My curiosity has been aroused ... so I googled.

    From a FZR250 forum ...

    the ON position is marked at 6 o'clock, OFF at 9 o'clock and RES at 12 o'clock


    An interesting link to said forum for the OP.

    Interesting. When putting in the new fuel filter, I tried to turn the fuel tap off and it still flowed out. Maybe on my one the off position is prime?

    Does fuel flow at the ON position ??

    Four positions possible ... top, bottom, left and right. Try all of these.

    What positions does fuel not flow without vacuum valve being activated ??

    Left is generally a bit tricky on the common three position taps

    Could be gunk in the seals, makes fuel flow in all positions. Is it large flow or just a trickle? My tap used to leak fuel onto the engine in reserve until I cleaned the seals.

    Some fuel taps object to being pulled apart (but welcome to try) .. and may well be a buggered tap. If the OP has it working as it should at the on position, and has a reserve that he knows he can use ... win win.

    And would be more than he knew before ..

    If those little ones are anything like the thousands, one of these is a good buy even if only for peace of mind. Wires straight in. http://www.trademe.co.nz/motors/moto...-547151082.htm

    Too true. I don't really want to pull it apart just yet but if it really does fail I'll give it a shot. It was only leaking (flowing) because I had the fuel filter off while fitting a new one.

    There's 4 positions? Never knew that, probably why it was leaking when I thought it was off.

    I guess because I went on that other ride when I didn't have a lot of fuel and so it basically ran out when I got to the hills and the fuel was away from the carbs and I was all noobish and thought wtf its broken? Its broken! I didn't see any dirt in the fuel when I drained the tank but who knows there may have been some.

    Had I mucked about with the tap I could have got it going, but for how long? Don't think it would have got out of Huia road easily though.

    Seems alright, been riding around South Titirangi beach and French bay today as well as going to the airport and back, did about 102 km. Went all along those hilly narrow winding roads and it was fine. Needs a few (5k) revs if starting from a steep hill but it doesn't seem to bog down. Spluttered once while decelerating on the motorway but apart from that its good as gold.

    Trust me on this ... the GREATEST fear of any biker ... is the fire going out. Silence is not THEN golden.

    When it happens (for ANY reason) it seems like the end of the known world has arrived. When you're a NOOB ... (been there .. done that) it feels even worse.

    Check list if it dies in future ... 1. Reserve on. (or it's NOT already on) 2. Check kill-switch is NOT on. 3. Recite small prayer to the motorcycling god .. that it will be a simple fix.

    Heh if you do need to switch to reserve, for the love of God make sure you switch it back to on when you fill up. Else you may find next time you just flat out run out of gas as I found out many years ago.
