I went through something similar with my little CD175 twin - got a smaller battery but was concerned the relatively primitive charging system needed a fairly large battery to absorb voltage output spikes, so, went back to a lithium battery with the same ampere-hours.  Didn't save any room to speak of and it was a really tight squeeze to fit it in, but at least no acid leaks.
Anyway, might be best to check that the Suzuki doesn't have a similar issue with its charging system and I gather you've deleted the electric starter - that little battery isn't going to turn it?

GS charging systems have a pretty bad rep, but if you switch out the OEM shunt style RR and replace it with a series RR (Google SH775, Polaris, etc) you pretty much eliminate the problems.

LI-ION battery cells aren't very expensive. The engineering and electronics necessary to get them working properly for motorsport use, is.

Don't go cheap on LI-ION, especially on a vintage bike.

Have you considered a battery eliminator? http://www.dotheton.com/forum/index.php?topic=73623.0

Gotcha. Small LI-ION is a good option then.

Unfortunately, all mine are shunt type. I still recommend them for the GS, but if you're specifically looking for a series regulator then you want MOSFET (preferable the Shindengen brand). Expect about $120 price tag for those.

Pretty sure this one is a fake / imitation of the SH775. If you haven't already, join up at GS Resources and search the forum for SH775 threads.





https://www.ebay.co.uk/itm/361952581100  Or this one



This one is a MOSFET - which isn't a true series style RR like the SH775 but will still work - I just haven't heard good or bad about them.

The SH775 is a series type. This type works by limiting the power out of the alternator by varying the resistance. Basically, this prevents your alternator from putting out full power unless it is needed.

The FH020AA is the shunt type were were talking about. With this setup, your alternator is always putting out full power, but the regulator bleeds whatever isn't needed back to ground.

Series type is generally considered to be superior, but is usually more expensive, too.
