d entire fuel tank into the engine
I serviced my carbs and replaced most of the jets & gaskets. Spray it all clean with Carby Cleaner & replace as many of the parts as possible. A carby repair kit won’t cost much. HEAT the Screws abd JETS before removing them so the brass doesn’t break. It’s fairly easy job & should improve your carbs. If not you should try to find WRECKED Hyosung with the same carbys. I’ve got 2x carbs & serviced both. You can get a new dual carb from Hyosung but costs almost as much as the bike. I alos found a similar dual carby that is the same size but has it’s throttle on the other side. I intend to see if i can move the throttle cable across to make this carby work, but it may not be that safe. It is for the Honda Rebel 250. The dimensions are the same so it will fit but i’ve not tested it yet. It is a very cheap priced aftermarket carburettor but it looks ok in quality. Cost me only $35 quid. But your best bet is to find a used Hyosung Mikuni carb & service it, if your own carby does not come good after a clean. They are MECAHNICAL so parts can be replaced to make them work again. My guess is your FLOAT NEEDLE is not sealing off the fuel correctly. Perhaps it’s O-Ring has failed. It is a cheap and easy part to replace. You don’t have to get the Mikuni parts to test if you can save your carby. replace the bits you can & spray the hell out of eeryhting in there. You can also get CARB JET FILES which are just peices of wire you poke in the holes of the jets to clean them. A strong Carby Cleaner spray can should do most of the cleaning for you. Marcel has some guides on removing the carbs and opeing them up and tricks like adding a bit of vasleine to the gasket and the diaphram to create a good seal, etc. If you have trouble removing a part or finding replacemet parts, you can contact me.
