I know this is a goofy question. On my 300 I mounted a battery in my airbox. converted to D/C power.  I want to mount the battery where it is on the 250. Will the left side cover from a klx 250 bolt on to a klx 300? 2007 model. The 300 cover is flat where the 250 is curved like the exhaust side. What are the chances that someone owns one of each. Thanks.
