Good catch Raul. It might be the problem if the bike is 10 or 11 years old.

This is Raul's starter clutch thread:

First of all.. thank you. All of you for taking the time to help me out. Second, I did make a video of the bike running and a couple of stills. The problem is that the idle sounds ok in the video (dunno about the clunking). The engine was cold and the idle speed was set quite low (because i keep fiddling with the knob while riding).
The true idling nightmare starts when the engine is hot during riding. That's when it revs and doesn't return to idle. I was unable to show that in the video because I couldn't take her out for a spin (brrr.. really cold rain).
So here are the pics and the video. Tell me what you think of the sound.

The idle speed should be set with the engine warmed up - set to 1300rpm. Then you do not touch it, and especially not while riding. Your idle speed is set too low
.
I don't hear the clunking you are talking about, maybe someone else does.

I may be wrong but here goes. Get the carb issue sorted out first. You need to be able to idle the engine in a warm condition at the proper speed to help diagnos the noise. At a very low idle speed most motorcycle engines sound quite sick because of the backlash in all the gears, shafts and clutch parts not running at a proper speed. Likely the cam chain makes more noise too. Also at lower idle speeds the oiling system may not be adequate to provide oil pressure for all the upper parts.
Just throwing this out for food for thought that may help others to expand upon.

Today I fixed my idling issue. It wasn't an air leak, although it really sounded like one. The "mechanic" messed up my mixture in the carb.
The pilot screw was almost completely seated. I turned it out 2 1/2 rotations and what do you know? It runs smooth and even.
Now I still have to have someone look at my clunking noises. But at least the bike runs fine.

Thanks guys! I'll post an update after the check-up.

When does the clunking noise occur? Engine hot, engine cold. Low RPM or higher? Does the clunking occur only when the bike is ridden or stationary and running?

[tudorv]

It is a barely noticeable constant clunking. More noticeable at idle or low rpm, and a bit louder when it's cold. And it's not the valves. I fixed that. I'll know more on Monday when I see this other guy.

Let us know after the 2nd opinion.

Air cooled engines do generate a lot of noise somtimes with nothing wrong. Hopefully this is a bike that likes to be loud mechanically.

Made a surprising find riding today. It seems 80% of the engine noise I was complaining about goes away when I pull the clutch. What do you guys make of that? If i hold the clutch I have a really smooth running engine. As soon as I release it, we're back to clonking..
