AVAIL Motorsports Cam Cover Vent (Color)
DHM Performance ECU Flash for the 2022+ Honda Grom/Monkey (ECU Core)

Howling Moto has put together a complete big bore build that we suggest is needed at a very minimum when installing a big bore kit on a 2022+ Honda Grom, Monkey, Trail 125 and Super Cub with the new style 5 speed engine.  The only items you would need to complete the build is an aftermarket exhaust and intake.

This kit includes:

DHM 149 Big Bore Kit

DHM S1 Cam


Avail Cam Cover Vent

PCX 150 Injector

Kitaco 5 Row Oil Cooler

NGK CR9E Spark Plug

UNI Filter Breather Filter

Cam Cover Vent Hose Line
