Feb 2010, Big Battery Install

My quad doesn't start unless the engine is cranking at a high rpm.  The stock battery was having a hard time keeping up and I run big HID's in the desert so I thought it was time for an upgrade.  There are companies that offer extra batter mounts built into big airboxes but I didn't want to run a smaller air filter.  I searched all the big quad forums looking for people who have done the larger YTZ10S battery swap but I couldn't find any answers.  The stock battery is the YTZ7S, it has 130CCA.  The YTZ10S has 190CCA.  I went to Interstate batteries to look at their batteries, they sell YUASA's which are the factory brand and highly rated and quite expensive.  I ended up going with the YTZ14S which is the same size as the 10S but about 1/2" taller and it sports 230CCA.  It was only about $8 difference so what the hell. 

I found a fabrication shop in Phoenix called The Future Fab, after checking out their website and the quality of their welds in person I decided to try them out.  I gave them the battery and told them to make it fit in the stock location with a new tie down strap.  I also had them repair and gusset my heel guards that were cracked.  Their turn aroudn time was awesome and everything turned out great.   You have to make the battery tray a little wider and build a new tie down.  You also have to extend the positive battery cable since the battery has reversed terminals compared to stock.
