I can't really explain what I'm trying to explain (lol) so I'll try the best as I can. I went out riding this weekend with a few of my buddies and as we were all starting our bike, theirs sounded like it started up a lot quicker than mine. My bike seemed to lag a bit as it was trying to start. I can't explain the sound but their engine sounded like it was starting up quick while mine sounded like it was lagging. Does the battery need to be replaced? Or am I just making a big deal out of nothing?
