Mystery Part Found In Petrol Tank

Discussion in 'Technical Help' started by West Cork Paul, Jul 27, 2019.

  1. Since posting those posts in another thread yesterday , apart from the round black plastic indented thing I also found this little round metal part with AEG stamped on it inside the tank today:thinkingface:. Do the two go together? Is it part of the Datatag sysytem and Roadtrip suggested? I've never seen whatever they use, I thought it was just irremovable labels placed at various points around the bike.

    Anyone any idea what it is please?

  2. Datatag transponder. Trovan supplied the datatag readers I was using in the 1990s.

  4. Thanks @chrisw and @Andy800 :upyeah: So @Roadtrip was right:upyeah:.
    As it had come loose and was rattling around inside the tank I presume I should stick the little AEG RFID back into it's holder and then glue it back on the inside of the tank. Anyone have any idea what's the best glue to use i.e. petrol resistible. TIA
     
  5. I’d be inclined to not bother. I doubt it’s an insurance stipulation

  6. They supplied Araldite to glue them. You had to make an insertion tool from coat hanger wire. Shaped like a ‘tick’. Allowed you to insert it through the petrol filler, move it forward and then raise to glue it to the top of the tank. The later tank transponders were also magnetic.

  8. I know that feeling :confused:
     
  9. If your current insurance hasn't been told it's there, I wouldn't bother refitting it there. there are plenty of places on the bike you could locate it too if you feel you absolutely must refit it.
     
  10. Talking about finding items in fuel tanks, I fettled a BMW R75/6 for my son and found a stainless mesh bag of lead weights in there - lead lumps 2.jpg presumably an antidote for lead-free petrol.

  12. I always worried that the adhesive would be affected by the petrol, so I used a self-tapper for peace of mind. HTH....

  13. Present insurer DNGAF about data tagging apart from which I didn’t know it was there so there’s no way any of my insurers over the last 20 years that bike’s been in existence could have known. It can stay on the work bench.

  14. Effective range of almost 12 inches according to the specs !
    Hmm , that's very ......
    :)

    Did anyone come across a micro-dot system that came in little bottle , like clear nail varnish ?

    I got sent it by Carole Nash years ago , and it was called " Bike DNA "
    or some-such , and it had a card with a barcode to keep safe .

    And as I was dotting it around the bike I thought -
    who the hell has the equipment to read this ? .... the police ?
    Who is even going to scan for it ?

  15. You've got bare electrical connections in the tank (some bikes).... get that out of there.....
     
  16. The 1976 R75 is not that electrically sophisticated, but the idea that dipping lead weights into petrol to make it "leaded" has got to be up there with the most crazy theories...bonkers.
     
  17. Is it lead?There are some snake oil products that look similar that are supposed to increase the performance of any vehicle that its added to.I think youll get the same effect if you leave it on the bench.
     
  18. Absolutely... I recycled it.
     
  19. Not lead, but tin.

  20. aaah - interesting! Many thanks for the information - that clears up the mystery. I hope it improves the efficiency of the landfill in which it now resides.
