hey guys new to this forum, i have a klx/drz-s and i want to swap out the carb for an FCR. i have a 37mm from a kx250f laying around not in use. just curious if anyone has done or knows anyone who was done this with a 37mm. i did search and could only find info was of someone asking if a 37 could be bored to a 39. my delema is do i use what i have and go into the swap blind or do i just scrap the idea and just buy the swap kit with the 39. i could car less about the possible loss of top end power with the smaller carb, all im after is to make it feel more like my mx bikes throttle response wise. any help would be appreciated and thanks in advance.
