Newbie here. Still working on my first XS400. Its winter in chicago so prefect time to build something. I've only worked on 2 stroke Mopeds so far. So motorcycles are a new ball game.
So my question. My mikuni carbs are trashed and I need new ones. I want to just find replacement mikuni bs 34s (77-79) but looks like its hard to find used ones for cheap. So I was wondering if I could fit on mikuni bs38s which seem like parts are easier to come by.
Also it seems like I could gain more top end from the 38s? I hear the bottom to middle throttle response is wacky but I came across a kit to resize the slide to fit a different needle to fix that response problem.
Are the 38s to big for the xs400? Am I creating a mess for myself?
Thanks, Party on!
