I have a 06 Ninja 250 with about 10k miles on it. Long story short is I got it second hand and rode about 3-4 thousand miles and the Kawi shop told me it needed a timing chain. So I got the service book and the motor out of the frame. the old chain looked work on the backside so the guy called it good just by the sound. I also bought only OEM parts. Problem is I don't have time for it now and think I should get rid of it to fund another bike I have. I think the timing chain might be over my head but not sure as I haven't torn into it. WWGRMD?
