Engine Ticking sound
Hi there folks. I've been lurking on this site for many moons and its always been helpful. Thanks a bunch. I actually have an issue, myself, that started maybe a week ago and thought Id see what you guys thought of it.
It's an 09 Ninja 250r with 8500 miles on it. Had all major suggested tune-ups by my mechanic. (600 mi, 2500 mi, 6000 mi). Been maybe 2-3k miles since my last oil change and looking to do that Saturday assuming I get time from work.
Changes to the bike: light integration kit, seat cowl, smoked windscreen, fender eliminator, and muffler. Muffler was recently changed back to stock OEM due to noise related fix-it ticket.
The issue is that its recently started "ticking" when the engine is running. I can hear it at speeds of less than 40-ish and it seems most prominent at 2500 rpm. (or at least most audible). The ticking speed is directly related to the rpms. "tick...tick....tick..." at idle compared to "tickticktickticktick" when gas is applied. When I initially start it, it wont make the sound. But when I rev it or once it gets warm I can hear it even when in neutral or standing idle. There seems to be no real loss in power, speed or performance, it is just pretty annoying and Im trying to get to the bottom of it before it becomes a bigger problem. Curious if anyone had any ideas?
Thanks in advance!
