convert electronic speedo to mechanical (Solution found)

[ordni]

Hi I am making some big changes on a 1990 fzs600 that has a electronic speed sensor and I was wondering if someone has found a mechanical speedo drive that fits to use with some vintage speedometers


Best regards Örn

Does someone have the dimensions of a xj600 speedo drive, retainer clutch and driver washer?
I cant get any parts here in Iceland and its not fun ordering parts and have to wait 2 weeks to find out that I cant use them

Could you make up an adaptor box with an electric motor governed by the pulse rate from the existing sensor?

GPS speedo, many different styles out there and probably no more expensive considering the cost of modifying your stock drive and then buying another speedo to replace yours

Don't have the knowledge to do that hehe.


And the owner of the bike does not want to use a gps speedo, he bought a speedo  gauge that he wanted to use and told me that I had to find a way to make it work

The obvious question has to be why they want to go for such old technology?

How about this as an alternative.

Take the guts out of the mechanical speedo and the standard speedo and switch them over. That way you get the look of the old one but with the modern electrical drive.

Not sure how easy that would be, bloody great circuit board in the stock clocks.

so if someone wants to know what speedo drive to use when converting to a mechanical speedo meter.

The answer is a speedo drive and caple from a Yamaha YZF 600 Thundercat.
Yamaha retainer cluch 341-25846-00-00
Yamaha Drive washer 341-25149-00-0


its a perfect fit, just plug and play.




















Have a nice day.

How do you negate the Rev counter error code when the ecu realizes it doesn't have a speedo connected (from memory generated after revving past 10k in gear)?

Hehe I have not fixed that problem and won't do it because the owner is so scared driving a motorcycle that he will never rev the bike past 7000rpm

Lol, not a problem then!

[joebloggs]

Please explain error code and what effect it would have on after market rev counters (I assume this would only effect counters taking rpm fron ECU)

[Punkstig]

Rev counter drops from current revs then up to a certain number on the counter indicating what the problem is/might be, I can't remember what number it goes to for missing speedo sensor, as for aftermarket clocks I've asked several times on previous threads for koso's and the such but never seen a reply to this!

[joebloggs]

Does it switch between showing code and rpm or show code constantly until reset

It shows code constantly until reset, but if the bike rpm are higher than the code it is showing it will jump to that rpm meaning it is all over the place.
