CB750c Tach Block off plug

thingiverse

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. The V2 plug just adds some contours to the end for aesthetic purposes. 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. I have yet to try to print nylon or ABS so I'm not sure if I will ever try it. NOTE: if it spins in place with the engine running, you will need to widen the hole so the square pin has more clearance
