Hi all.
I've been working on a bobber conversion this winter. Thank god for this project since I can't travel at least I have a project to fill my time.
I've done a bunch of reading on this forum about the smaller battery options. For various reasons which I am sure are debatable I want to stick with an AGM battery.
I thought the ideas about the YTZ7S battery are brilliant but I would like more than the 6 AH capacity that it has.
So after reviewing different battery sizes, I thought that a YT9B-BS battery may fit. It claims 8 AH which is a 33% increase over the much talked about YTZ7S however the CCA is slightly less. The YTZ7S claims 130 CCA while the YT9B claims 120 CCA. I think it should be sufficient ??? The Yt9B is the same height and width as the YTZ7S but it is 1 1/2 inches longer and would extend under the swing arm cross member.
I made a wood mockup of the battery to be sure that it will fit. I have 1/4" clearance under the swing arm cross member. I had to remove the exhaust and the front belt sprocket cover. Then by loosening the bolts of the exhaust hanger bracket, I can pivot the bracket and slip the battery in. A bit of work but if I only have to do it every 2 to 3 years I don't mind.
Not sure yet whether to go with a Yuasa brand or generic. The Yuasa is twice the price but I am pretty confident it will out last a generic.
This is a bobber and I am changing the rear fender. This battery install will not work if keeping the oem fender.
Before I proceed with this, I would appreciate any thoughts from the forum family.
Here are a few pics.
