    Need Help FZ6 S2 Misfire at Idle and up to 3k on partial throttle

    Thanks very much. I'm losing the will and desire with it now. Looking at Tracer 900 I have no way or time to do all the necessary tests. The only option I feel that I have is to take it to a garage or yamaha dealer. P*ssed off and don't know what to do

    Need Help FZ6 S2 Misfire at Idle and up to 3k on partial throttle

    Can't send the mp4. Do you know what format the forum accepts? I've just put the K&N back in and took her for a rip. Top end absolutely fine to redline all gears ( couldn't try 5th and 6th obviously :) ). Also tried letting it go to like 15 mph in 6th on almost stalling and then cranking open...

    Need Help FZ6 S2 Misfire at Idle and up to 3k on partial throttle

    Had the airbox off again this morning and all hoses are connected and perfect. Put a carb balance vacuum ( really old style one ) on each intake and they all pulled similar level vacuum closed and open throttle. Really strange. From idle if you snap WOT and hold it there is just coughs like mad...

    23k, but all this just started suddenly. Valve clearance increase would have been gradual, surely? You don't think it's fuel pump related?

    No, I don't think so. Just ridden it pillion up with a loaded back box and returned 62mpg. Goes like it always used to above 3k to eager redlne. Just idles like crap and misses up to 3k. No idea.

    Need Help FZ6 S2 Misfire at Idle and up to 3k on partial throttle

    Hi again all, After having solved my top end problem 2 weeks ago by changing the plugs, fixing a vacuum leak and reassembling my fuel pump correctly, the bike has just started hesitant starting again and a super lumpy idle and up to about 3k rpm. Road speeds it rides perfect and performs as it...

    Need Help 2007 FZ6 S2 Fazer Severe Loss of Power ( galloping ) 9k RPM upwards

    Final update. Thank you so very much all for your advices. Bike is back to perfect. No hesitation, redline eager as it used to be. Smooth. Found a crack in cyl 1 vacuum hose, plus new plugs and a good blast out of the fuel system cleaner. Topped up with super and some octane booster. That was...

    Need Help 2007 FZ6 S2 Fazer Severe Loss of Power ( galloping ) 9k RPM upwards

    Update... Battery on charge all night. Changed the o ring around in the pump again as I found a photo with the o ring on top. Starts and runs perfect. Took for a ride, hesitancy still there but at least its going. On a side note, battery seemed to drop down real quick after a few cranks, so I...

    Need Help 2007 FZ6 S2 Fazer Severe Loss of Power ( galloping ) 9k RPM upwards

    Probably 3 times what they say. Now, probably a 1/2 I hit it with Seafoam and some other decent recommended one. When it was running normally I used to fill half the time with regular and the other half with super, adding octane booster and clean every 3rd thankful.

    Need Help 2007 FZ6 S2 Fazer Severe Loss of Power ( galloping ) 9k RPM upwards

    Thank you. Honestly, what do you think try next? Do you think there's mileage in buying a 2nd hand pump and trying it? I have no idea where to go next. No wiring has been dislodged, I've checked all visible connectors and grounds. I don't think the problem is electrical, spark or air related. I...

    Need Help 2007 FZ6 S2 Fazer Severe Loss of Power ( galloping ) 9k RPM upwards

    Update... Took the pump out again tonight. Learned the flow actually comes out of the side of the outlet tube and the bottom half of the tube goes to a spring prv that vents to the tank. So, fitted the o ring UNDER the pipe adaptor and installed that flange down on the o ring, thinking this...

    Need Help 2007 FZ6 S2 Fazer Severe Loss of Power ( galloping ) 9k RPM upwards

    Further question please all, Would a battery on it's way out cause all of this? It's been on the charger all day and still only on light 2/5. I know I've been cranking it a bit but even so.

    Need Help 2007 FZ6 S2 Fazer Severe Loss of Power ( galloping ) 9k RPM upwards

    Blew through both the vent pipes from the tank this morning. All clear and fine. No kink in fuel line. Would you buy a 2nd hand pump? Because I've lost confidence in my re-assembly of the pump

    Need Help 2007 FZ6 S2 Fazer Severe Loss of Power ( galloping ) 9k RPM upwards

    Thanks very much! But thats all far beyond me. I'd like to know first whats happened with that pump, it doesn't make sense. I've tried putting that little adaptor and o ring back in both ways and no change. Didn't change anything else on the pump. Thinking buy a 2nd hand pump so I can remove my...

    Fuel Pump Rebuild?

    Hi all, I have just taken my pump apart to clean the filter. Unfortunately that little o ring and strange plastic outlet pipe "adaptor" fell out when I halved it, and I don't know which way they are supposed to go back in. I THINK the flanged part of the adaptor was facing towards the bottom...

    Need Help 2007 FZ6 S2 Fazer Severe Loss of Power ( galloping ) 9k RPM upwards

    Now i can get it to run but only with holding the throttle slightly open at 2 to 3k rpm. It will sit there running, but lumpy. Second I close the throttle it slowly dies over 30 seconds
