Jets, Jets and more Jets, I had the same problem with my GS400 it had been in a barn for 19 years and was still running the standard jet sizes, modern fuel is shit now, full of chemicals and ethinol not like it was when these bikes were new, just keep jetting up till it settles. My GS400 is now running on nearly double the main jet size and the pilot is now 45 (the std was 22.5) she runs as sweet as nut now
