    Yum. I'd go for black wheels meself.

    That mod for the gravity feed is an interesting one... but I can't help but wonder if it would be a better idea to replace the fuel tap with a larger one that can flow the necessary fuel without disposing of the vacuum feed?

    I knew a guy once who swore he'd seen a bike leak that had spent the night leaking petrol into one cylinder. Owner came in in the morning, turned the engine over, raw petrol didn't compress too well and he bent a conrod. Smells of urban legend, but its a good excuse to turn your fuel tap off at night.

    Personally, I always found that vac valve on the RVF a pain in butt if I left the bike more than a week between rides. Bowls would empty, and I'd have to crank the bike just to fill them up.

    If I was lucky, they'd fill just in time for the engine to catch as the battery lost its puff. If I was unlucky, I'd spend three minutes cranking and then another ten pushing the bike up the hill and bumping it back down.

    Solution? Ride more often.

    always pays to fire your bike up often....

    i don't think the carbs would go dry, more that the fuel goes a bit shitty, fuel should just sit in a bowl....

    yeah my old gpx made me very skilled at roll starts lol (cheers frosty)

    Well, it's good for the soul, if nothing else.

    Go off in a week? To me, that seemed less unlikely than the heat-soak up from the engine heating the carbs and flashing off the gas in the bowls. The engine temperature used to spike (because of riding conditions) just before I got home and parked up. But, thinking about it now, if heat-soak up from the engine was the problem, it wouldn't take a week, would it? It'd be gone the next morning.

    Who knows?

    What I do know is that I'd have that RVF back in a heartbeat. I should have shipped it out here.

    *sigh*

    Not a urban legend, I've had it happen to me on a Ducati I used to own and have seen it on a few two strokes,normally only when the needle and seat aren't sealing properly

    Well, that's two blokes I've never met whose names I don't know who claim to have had this particular experience -- it *must* be true!



    I've never seen it, but I did have a TS185 once with a dodgy bowl seal that peed a litre of BP's finest all over my drive. The only bike I don't habitually turn off when I park it is the ZXR750 I have now, and that's only because the tap leaks when I switch it to "off".

    Another member on here had to fix his motor when he bent a rod from the same thing happening, and one of the funniest things I've seen was two guys at Ruapuna crash starting a RGV250 and having fuel pour out one of the pipes (litres of it)
