    My 1984 XJ900 is my everyday transport, and has been for years. Has 110,000 km on the clock but runs beautifully and is very reliable, EXCEPT if I leave it for more than a week, it refuses to start. Easy enough to fix-I pull the two outside plugs, spit some petrol through the plugholes, she starts and runs, the problem vanishes.
    As long as I run the bike up every few days, it doesn't happen.
    What's going on?
    Water in the tank would be my first thought; some problem with the petrol tap would be the second.
    I'd love some suggestions from experts!

    Does your ordinary starting procedure involve using the choke - enrichment?
    If using the choke still won't provide a rich enough mixture, I'd suspect you need to clean that circuit in the carbs.
    Have you tried using ether based starting spray in the air cleaner box?

    Another thought, after sitting for more than a week possibly the fuel has evaporated from the float bowls. Do you put your petcock in prime for a bit to refill the carbs prior to pressing the start button?
