Engine Knocking

My "99 KLR has a knock coming from the engine when I lug it or let the clutch out with the brake on. I am using premium gas so I doubt if it is pre-ignition. It's not like a heavy metallic knock like a car engine with a rod bearing gone .. but a sharper pinging sound. There is no noise at idle and is not noticable when riding with a full face helmet. It doesn't sound like it's going to blow up or anything but is definitely a concern .. Any ideas ????? ... Rod

How many miles?
Mine does the same thing. I THINK its because they are jetted a little lean, anyway if your motor doesn't have an obvious knock at idle don't worry about it.

Change oil as suggested and if you see anything other than tiny glitter you have a problem, but mine makes same sound and its just because you are lugging it a bit.

Thanks for the advise .. as it turns out I talked to the dealer about it yesterday and he said the same thing. He said after a few miles they get a bit of carbon build up and tend to ping a bit ...said to turn the screw at the front of the carb 1/2 a turn and it should go away ... Rod
