Went to a vintage meet last weekend on the other side of the state. No problem getting there or leaving, but after stopping for gas, the R65LS wouldn't start. All I got was clicking. Two guys on Harleys gave me a push. The previous owner tells me the battery is six years old, so my I plan is to replace it tomorrow. The local BMW dealer quotes me $190 for a battery, while a local m/c parts store has a designed-for-a-Harley YTX20L-BS (as listed in the stickies) for $80. Just want to confirm it'll fit and work. The guy at the store said the battery is 7/16ths of an inch wider than stock R65 battery. Think it'll do the job?
