FLOATERS FOR HSR42/45 AND TMR42/45 CARBURETORS
Manufacturer reference: 859-32027 — Brand: MIKUNI
This replacement part is designed for Mikuni HSR42/45 and TMR42/45 carburetors. These floaters maintain the fuel level in the bowl, a central element of the carburation process. Sturdy and designed for easy replacement, they help ensure the proper functioning of the filling circuit and prevent issues related to incorrect bowl levels (clogging, acceleration cuts, or difficult starts).
Practical tips: when replacing, also check the condition of the needle and seat, as well as the sealing of the bowl gaskets. A correct float level adjustment is essential for stable carburation — if you are unsure about the procedure, consult a tuner or a specialized workshop. An essential part for any engine preparation enthusiast or routine maintenance, it is part of the maintenance routine for Mikuni carburetors.
