Air cleaner maybe.
. Bad eexperience.Good advice.The fine filterscreen on the fuel pump can become encrusted.
No amount of techron did anything to clear mine.
I ended up having to replace it and did the fuel filter bypass/external filter mod.
Ethanol gas is insidious, I only use it when I can’t find non ethanol.
At the very least fill the tank to the top with non ethanol when storing it and maybe some stabil , run it a bit to get it into the injectors.
I had to clean my injectors ultrasonically and it was incredible how much crap, varnish from sitting gas came out of them.
Sometimes they just need a good spanking.I just took it out and rode it for a couple hours. It seems to be running perfect now.
