Another Battery Question
08/08/18 at 08:07:02
Post Tools
Hi, I've just bought a 1980 R65 that's been standing in a garage for some 20 years and, oddly enough, needs a little work to recommission it!

I've been busy collecting data for this make and year and I'm having problems finding out what battery was originally fitted to it and what suitable alternatives there are available now. I've found that the space restrictions in the "battery compartment" seem to rule out some of the ones that have been recommended by local retailers.

Can anyone shed any light on this, please? I'll, no doubt, figure this out in due course along with how I can get the locking fuel cap unlocked (I've tried the key!!)

Thanks for your help and for letting me join the Forum.

Regards,

Tony

There's a trick to the fuel cap when it gets stuck, I don't know it (cause the monoshock one is better?) but you can probably find it here with a search.
  

'86 R65 with '84 motor ~66000 miles.  SS lines, Spiegler rotor, Progressive monoshock, Keihan silencers, a piece of Pichler fairing.
'76 CB400F ~26000 miles.  Weepy SS lines, big dent in the tank.

This is from memory, and I would research it first! Pass a rope through the fuel cap handle. Tie both ends together (leave enough length)  loop around your neck while sitting on bike. Stand up on pegs and pull the cap out like a cork from a bottle!  Hope this helps.

Regards !

Search PC680 and that will bring up all kinds of batteries

AGM type is the best way to go

I got my first PC680 battery in 1999 paid $65 delivered to my home .
The last one I bought was $120 delivered, and lasted 25 months, that's when I switched to generic AGM batteries .
The unrelenting heat here in the low desert usually kills motorcycle batteries in less than three years, no matter what you purchase .

For the fuel cap wrap a rag around 360 degrees under the lip and apply pressure upwards.  Assuming you have unlocked the cap (50/50 chance here).  Then with the handle turn the cap until it starts to unscrew. 

If the internal "link" is broken it will not turn so you need to apply the upwards pressure on the lip. 

You can buy a new cap (expensive) or drill and put a small bolt in the cap which means you can not lock it anymore.  I hope this makes sense.

However, Motorworks have a reproduction item and various other options.

Eventually got the filler cap off after pouring loads of WD40 in to release it. It was rusted out, though, so I need to get hold of a replacement. I understand that Motor Works can supply S/H ones without keys which is probably the way I'll go.

Battery was easier, I got an Exide from a local dealer. It fits well and turns the engine over. So that's good.


Thanks for all your help.

Tony
