Hello, i want to ask about a problem with my fz110 non S version. The engines has almost one year and was running in per instructions. I tried all the method found here to set it right, but it always start having mid range problems about 4 mins after running. The full throttle is fine, with some oil smoke, but when I reduce throttle to 1/3 the engine just trie to quit. I have opened the regulator, but it made the same thing, it take more time or it does it in lower rpm. Also when I stop the engine, its spill a lot of fuel from the carburator.
I have done almost everything, but it doesn´t run fine.
I am about to sell this engine, but I wonder is if there something that I could change, like the regulator, to make it run fine.

Thanks,
Alejandro.
