Please Help Me!!! I've tried the Search button but couldn't find anything. I have noticed this sound is becoming more frequent over the past week or so and I'm getting very concerned about it. When I start the bike I have approx. 85% choke. About 20 sec after it has started there is a sound that is like a wire rope (like the clutch cable) that is being whipped on a metal casing??? It sort of sounds like... well yeah... something inside the engine whipps around. It definately isn't constant (doesn't sound like it goes 360 degrees round the engine), sort of once every couple of seconds or so. After maybe a minute its frequency is less. The sound is still present now and then during my ride to work which is about 50ks. The bike has almost 11,000ks on it. It is due for an oil change, been about 4000ks since last done. Was going to take it in for the 10,000 service soon. Any help/suggestions would definately be appreciated. Thanks.
