I did not see your comments before buying from the second hand link that was sent in. Have I just brought a broken second hand speedo drive?  :o

No probably not, the broken part we speak of is the rotor sensor which fits inside the speed sensor you have bought from my link, the rota has a broken lug(s), this is the new part (rotor) you have had fitted recently, when you receive the speed sensor you can take the damaged rotor out & throw it away & fit the  replacement Ebay speed sensor.


The Rota sensor/ speed sensor see fig 13.

Thank you for explaining this for me, I will check the rotor sensor in the speedo drive when it arrives, the one that is currently on my bike I will have to see when the wheel is back off to see if it is not broken, if so, looks like i'll have to buy another rotor sensor.

I know it's a nuisance, but if you bought the one in the link that was given it says "good condition, tested, works", but if you get it and both lugs are broken, which i suspect is the case, then it probably wasn't tested and doesn't work.
Up to you if you want to go down the refund road, or maybe even enquire if they have another rotor they could swap it with.

UPDATE!!!!!!!!!!!


The speedo drive I ordered arrived and yes one the the lugs is broken however not both. I decided to take the bike out tonight for a ride and annoying the speedo worked perfectly, at slow speed, when cruising and even when letting off the throttle the speedo would drop correctly, this speedo issue is doing my nut in, can't understand why all of a sudden the speedo decides to work perfectly for me  :rolleyes

That's really annoying when that happens,at least you have the spare speedometer drive if it goes again.  [img alt=Smile]http://foc-u.co.uk/Smileys/efocicon/smile.gif[/img]
I would suggest it maybe a bad connection at a electrical plug which may need investigation.
