Replacement for GS750 kph speedo.

[BrianUK]

Hi all,

My first post on here

I have a GS750 with a kph speedo, and would like to replce it with an mph one.  Does anyone know if a GS550 one would be a direct replacement?  It looks the same, and according to the (sorry!) Haynes manual the front wheel is the same.  I've tried a search on here, but I couldn't find anything about this.

Thank you,

Brian.

Yes, its the same.

I have 550 clocks on mine, just tacho redline is different.

Brilliant!  Thank you very much for replying. 

I was also wondering if anyone knows if it's it's possible to change the mileage on the 550 speedo?  My bike has done (I think) about 44,000km, which equates to about 28,000 miles but the 550 speedo I've bought (I was 90% sure it was compatible at the time) has 55,000m on it.  If possible I'd like the mileage to be correct for the bike.  Is the mileometer part made in such a way to prevent this being done?  "Clocking" and all that? 

Thank you again,

Brian.

My take some time, get a Speedo cable attach to speedo, then get high speed drill attach to other end of cable secure both items and start drill and watch the miles fly by  but it's not a 2 minute job 

And make sure the drill is going the right way and not backward as the Speedo only hose one way.

Thank you very much.  I did think about that, and did briefly try it with my cordless so it'd work, but as it only goes forwards I'd have to take the mph one from 55,000 through past 100,000 and on to 28,000; that'd take 30 whole days at 100mph.  So I was thinking of the possibility of taking the mileometer to bits and rearranging the cogs, but in reality I'd probably knacker it up. 

It was just a thought!  Thank you for all the replies much appreciated.

Regards, Brian.

it's been done many times but it will always be visible, the cogs don't line up perfectly after  they've been rearranged.

Thank you, I reckon I'm going to leave well alone.
