Hey guys, thought I would resurrect this one than starting another. Seems like I have been having something similar as of late. It's a '15 with only around 3600 miles, but the bike just cranks and cranks for about 10-15 seconds before firing. Riding it seems okay, not sluggish, no misfiring, nothing out of the usual. It is only starting.
I recently put fresh gas in, changed the oil, checked air filter, everything is new and in spec. Possibly an electrical problem? Though I'm the world's worst electrician. The battery, however, is still the original but still seems to hold charge just fine. I tried checking the spark plug but unfortunately it cannot be taken out without removing the fuel tank, there's just simply not enough room. Looking if anyone has any ideas before venturing down this path.
