Any cutting of the carb holders and you’ll get crap inside the engine.
The easiest way is to pull the carbs. Anything less would be a nightmare IMO. There’s o-rings too.
I looked for O-Rings on partzilla. They arent listed. A member here told me there are no o rings on a 78 KZ Twin. Do you have a part number or link? Makes sense there would be an O Ring but diagrams do NOT show that there are any.
