Not too familiar with bikes, but I am curious as to where batteries are located on Yamaha WR's with electric start (not even sure of what models come with E start, but skimming through the threads I think the WR450 have it?) So taking that bike for example is it a bit bigger than say my 2000 WR400F that they have a suitable place for a cranking sized battery? I have a Dakar Dual sport kit on my bike and am looking to add a bigger battery to prevent my lights from dimming (almost nonexistent) at stops and my GPS from losing power everytime. I also may add some aftermarket lights for added visibility since there is lots of deer around. I am thinking I am kind of limited to mounting any battery in my air box. Thoughts and ideas are appreciated!
