ive been told that the stock battery is too small for the bike. guy at the bike store told me that i could go up to a 14 as apposed to the 12 in the bike? can i? has anyone done this before? again, help! i just had the start clutch replaced and they said the small battery helps to cause this problem. i don't mind modifying the battery case. most of the 14's i looked at will fit except they are too tall. that i can fix. need help if anyones does this. thankyou, mike
