Im looking for some help identifying this Mikuni Carb! We want to buy a rebuild kit for it, but need to know what model it is. Model number isn't stamped or sticker anywhere on the outside, it is currently attached to an 80" eve engine on a Frankenstien softail that was given to the owner, there may be a chance its not even a real Mikuni. I believe it's an HSR42 variation, but I cannot find anything with the similar left side throttle cable roller and downward pointing adjustment screw out the side. any help would be munch appreciated, thanks.
