CB750c Tach Block off plug

This is a little part to block off the tach port on the valve cover for a 1979-1982 Honda CB750c Motorcycle. I expect it to fit any of the early DOHC bikes from this era including the cb750 c/f/k as well as cb900 and cb1000 variants.

I designed this with the intention to block the port where the OEM tach plugs in after I swapped to a digital all-in-one speedo/tach. it uses the existing set screw to keep it in place.

This should print fine without using supports.

NOTE: This requires a high temp filament. I printed with PETG and it got soft after a 10 minute ride but I'm not sure if it will get hot enough to deform and flow/puddle.

I printed V2 in PETG and painted it with high temp paint and will see how it holds up. PETG with high temp paint held up for a 10 min ride (that's my commute). Currently testing unpainted ABS.

V2_1: Hole was enlarged slightly to allow clearance for the tach pin.
