1 pc. Muffler kit for Honda K1 twin cylinder engines.

Similar to the 622000 or 621600 Honda Muffler

K1 series. Not for older K0 engines.
Exhausts on left side of engine when looking
at the crankshaft.

(starter side exit)

Note: K1 Series engines have 1 bolt that hold the valve
cover on. K0 engines have 4 bolts that hold the valve
cover on. You can also tell the difference by looking
at the air filter assembly. The new K1 series has 4 clips
that holds the filter cover on, the older K0 style had a
bolt that goes into the center of the filter cover.
We no longer sell K0 engines or muffler kits.
