Hi, folks! Im a new member here, and would like some insight to a problem that has been vexing me...

I own a 97 ZX900R Ninja with 15k miles. It currently has a Hindle round slip-on. I bought it new as a hold-over in June 98, with 6 miles on it. I change the oil religiously, and take good care of it with routine service, etc. For the past few years, I have noticed a sound similar to a rattling, or marbles bouncing around, upon cold start-ups, full choke out, eminating from the top-right side of the engine. After a few minutes, once the oil is flowing, the sound goes away, and the bike runs fine. But it is definitely noticeable at start-up, and it has gotten somewhat louder and lasted in duration, as the years have passed. Some say it's just the nature of the engine, (a Kawasaki trait) other mechanics I have left it with say they didnt notice it. Believe me, it's there!! Forum responses have listed the cam chain and the cam chain tensioner as likely culprits. What is the history of these engines? Do you think I am on the right track? Also, almost since Day One, I have noticed the distinctive smell of antifreeze when the bike is at operating temps, yet no source is found. Can you please help? Thank you in advance for any and all input!
