I was wondering if anyone had any ideas on why the front sprocket on a Ninja 250 is making a buzzing sound. The chain is tightened correctly and lubed and the sprocket teeth are all normal. I think the bike has been doing it ever since it was new. Any ideas on what the problem could be? Should I call the dealer and attempt to make a warranty claim?

Thanks for your help.

How many miles on the chain?
Was it ever adjusted?
How often has it been cleaned and lubed? (should be every 600 miles or when it doesn't look wet)

Worn out chains get noisy. You can identify a worn out chain because the links bind and kink.

Too tight chains typically "whir."
Too loose chains slap the swingarm.

Regular cleaning and lubing extends chain life.

The bike has 500 miles. Chain was just properly adjusted (it was slightly loose). Unfortunately, it was just cleaned and lubed for the first time at 500 miles.

I don't know if you've already done this, but the folks on this site: http://forums.ninja250.org/ are really knowledgable and helpful if you ask nicely. There's also a FAQ section about that bike on the same site: http://www.ninja250.info/ that's good for a lot of DIY stuff.

If it's a zipping sound, it's normal, especially if there is a lot of lube on it.
