Use e5 forever. E10 will just ruin everything later even piston rings, as it looses speed as time goes on. = Valve Clearance time & Compression test time. Can’t be avoided. I’d do this first before worrying about the carb, you want the engine proper sound first. get hard figures , don’t trust anyone who doesn’t write it down. Change the oil. (Open your “oil filler cap” near clutch cover, if you smell fuel = change the oil to Motul 7100 , 300v , 5100 or Silkolene Comp 4 , Hyos love these oils) Castrol ? = Run away from it. EGR Blanks are sold on this shop for the engine side. Airbox side = block the hole going to the EGR. EGR is useless these days for carb bikes.
so I will have to take it to a bike mechanic as I don’t have a compression tester or valve clearance tools
