Haha yea, you are right. If I remember correctly it is for the most part present, when the engine is cold. The bike is in winter storage at the moment. I can update you, after I get it back in march. However aren't the 1. gen monsters known for piston slap? I read about in here: www.bikeboy.org/600monster.html
Don't worry I haven't forgotten you. I'll get my bike some time this week or the next:). But in the meanwhile I have figured out that piston slap are somehow quite common for the old 600's pre 1998. Heres a guy mentioning it on a report though. www.bikeboy.org/600monster.html "One of the "early" pre 98 600’s, it has the forged pistons that make the horrible slappy noise when cold, not that it gets much better when it warms up. Sounds like the insides are trying to get out, but we’ve been saying "they’re all like that" for so long that I have to believe myself. I had the chance to pull one apart recently to test the theory, and yes, there was nothing wrong with it. Just very short pistons with quite a bit of ( but not excessive ) piston to bore clearance. We replaced the pistons on that one with the cast pistons from a later model ( which supercede from the early ones anyway ) to make the owner happy. Slappy no more. That’s going to drive me nuts now every time I start ours."
Hey Sounds like youve got a little piston slap on the front cylinder, how long has it been doing that?

The mechanic said it's normal. He measured compression, still original strong compression numbers.
