Can it be removed ?

Im still using the hitachi carb.

Yeah, you can. As long as it doesn't get below freezing where your at. Without the bypass to warm the carb and intake, it'll actually freeze the moisture in the incoming air due to the velocity and it will freeze to the bore and the throttle plate. Next thing ya know... You no go! lol If it gets cold enough, it will actually freeze the air fuel mixture doubling the effect. Had this happen with a CJ7 I had. Turned the carb into a block of ice. Of course, it was 20 below and we were running wide open chasing deer in a farmers field.....
