Wrong heat range plug for the fuel and/ or riding conditions
I have a 1982 Honda Nighthawk. If you remove the bolt in the front of the motor on the bottom the fins and bolt will drop down. You will then see the oil filter cartridge. It looks like an air filter but it is for oil. Change the cartridge and reinstall.
It's either a fouled spark plug or your drive chain is stretched past its adjustment point.
This is given as 26 mm according to the information I have.
