CB750 K1 Speedo Mechanism

[kent400]

I have a K1 speedo that is very badly corroded (see images) and the mechanism is beyond all help. It's the type with the angle drive on the back. The body, inner body and the base I can restore. The angle drive is fine.

The gauge has clearly has a quantity of water in it for quite a long period of time. The glass is intact so it must have been left outside face down outside or maybe fished out of a river. There's a rusty tide mark on the glass.

The bike is a USA import purchased from DK, the tacho is not in the same condition and so it seems the speedo was fitted just to make a complete bike here or in the USA.

The owner of the bike isn't a forum member, should be and needs to be!

I have a gauge which IIRC Peter Horton identified as off a 750 which I bought thinking it was off a 550F2 as the face is blue. Numbers up to 140 then 2 lines, trip meter on back, angled drive, quite a long one as well. 2 bulbs. Has a small printed sign on the base which says 057100-5721, 2240 rev = 1 mile. It's a ND gauge.

Any use?

Thanks. The K0 and K1 has angle drive secured by three screws on the base. The internal mechanisms are a completely  different design and gauge drive spindle has a spiral gear.

Have you tried Peter Horton, he has LOADS of spare parts for gauges.

Peter Horton IS Kent 400, or did you know that and are trying to trick us 🤔🤔🤔😂😂😂😂😂

I was thinking it was the 400 who lives in South Africa. My mistake, I didn't for a minute think Peter would ever be short of a part as he has loads of them.

TTR400 (in South Africa) does make loads of very cool stuff. But not speedo innards…

I'm sure he could, if he put his mind to it.
