      Hi All, has anyone else come across this problem, if the bike sits for about a week without being used the fuel petcock sticks. This has happened a few times and have had to remove the tank and dismantle the petcock, just wondering if there is a permanent solution to this problem!

      Have you also unscrewed the bottom of the petcock (fuel tap) , to see if there is a lot of trap and do you use  RON95 or E5 fuel ?

      Here in UK, we usually try to advise owners not to use E10 grade fuel due to the fact it messes up fuel systems for the bike and is corossive if stood for too long , due to bare metal inside the GV tanks.

      Hi Marcel, I only use E5 (BP Premium) yes checked the trap each time and always clear. I was only away for 5 day’s and it has seized up, every time it happens I strip it down but there is never any sign of a problem, really can’t understand why it happens!!!

      It sounds like as a precaution , it could be time to just change it out if that’s the only issue on the bike.   Actually, its not uncommon either for vacuum taps for GTR bikes to crap up early on so you ain’t entirely alone in this

      Ideally you want the tap always shut when the engine is off , so there is no fuel in the cylinders overnight or hydrolock happens or soon seized piston rings as fuel has mixed with oil overtime.

      Have a deep sniff through your oil filler cap just to make sure, you know a strong fuel smell or oil looks watery and jet black.

      Hi Marcel, I always turn the tap to off after riding, it just feels like it sticks, can I use some sort of grease or oil on it?

      You can open the bottom dirt trap of the fuel tap and remove tap from the tank anyways.

      Use carb cleaner to soak it through all over it and check  ON/OFF/Reserve operate smoothly when twisting the knob.

      Spray carb cleaner inside = nothing should come out of the output hole.
      Spray carb cleaner inside & switch to “ON” or “RESERVE” the liquid should flow out easily.
