If U do a search on the manual cam chain tensioner, there is one to purchase for your bike. Not expensive. Also I have read a little about the new light weight Shorai battery which is supposed to have much more cranking power than lead acid batteries and much better than the turntech battery. Also it's supposed to outlast other batteries by quite a bit. Might be a good solution. They're spendy, but since they are said to last longer and crank better, might be worth it.
