Beware of rebuild kits, they often contain the wrong size jets. Most of us don't use kits. The jets are aftermarket and we prefer genuine Mikuni ones. About the only useful item in the kit is the float bowl gasket, lol, but most of the time you don't need it because the original is still good. Original gaskets are very robust and can usually be re-used if not damaged during removal.
I don't disturb or remove the choke housings, so no need for a new gasket there. I just pull the plungers out of the top.
There are only 2 o-rings in this carb, one on the needle jet and one on the mix screw. Neither will come in most rebuild kits. For the needle jet, a 1mm x 4mm is a suitable replacement. For the mix screw, we've found this size to be perfect .....
