Was hoping to install the bigger battery tonight and it's too tall for the stock battery case, i.e. the seat won't go on. Looking at KTMHutt they reference a part as an EXC battery case, part #78011055000, but it looks like what I already have. I guess the guy I got the bike from didn't have the 2nd battery case for the taller battery that I heard was supposed to be included with the spare battery. Anybody have a part # for the taller battery holder?
