DDM velocity stack with 5/8" inner diameter.
This adapter allows you to use aftermarket clamp-style air filters with 1 3/4" inner mounting diameter.
Precision machined for smooth air flow. 3/4" height yeilds better low end power than stock. 30.5mm center to center bolt hole spacing.
Dual outer grooves for sturdy clamp mounting.
Fits Walbro WA / WT / WYK style carburettors.
If using with a WT-style carburettor that has a butterfly choke, the center hole will need to be slightly enlarged.
The "AF310" v-stack is a better choice in these cases, as the center hole is wide enough to accommodate the choke plate.
Velocity stack gasket is not included.
