While getting to know my GS500 better, I opened up the carburetors ( I have installed a K and N air filter and was doing the recommended carb adjustment) and managed to lose a couple of springs. Well I lost one (it went springing across the garage and I never found it) and managed to tread on and wreck the other. I have contacted a wrecker (Dandenong) and been told that they will not wreck carburetors. I have found a number of overseas sites that allow me to select the parts from an exploded diagram. They want about ten bucks in total for a couple of springs which is exorbitant but fine, but then they want $50 for postage and I'm going to have to be pretty desperate before I pay a total of $60 for a couple of straightforward little springs. I explored ReShip and they want 5 bucks to sign up, five bucks per parcel, plus shipping costs of $50 unless I go standard US post which is $10 and may take up to 90 days!!! Still looking at $30-40 minimum for 75 cents worth of springs. I can't find an Aussie site that offers the parts. Right now the bike is running with springs of approximately the right size/length/stiffness which I cannibalised from a couple of retractable pens on the needles (I switched out the non-missing one as well so they'd be the same), and one carb is running without a piston spring (the big one you encounter first when you open up the carb) at all. Unsurprisingly, though the bike runs fine, the fuel economy is not awesome just at the minute. Any ideas on how I can get these bits for a reasonable price?
