Does it just knock for a few seconds then go away? Or is it a constant knocking sound~. makes funny sounds when it's cold and all the oil has drained down.

If it has hydraulic lifters, which I doubt, these make noise before oil pressure gets into them.

Without actually hearing it it's difficult to say.
The F2 & F3's were notorious for bad cam chain tensioners which will make some noise. Not a real big deal as long as you get it fixed.
If you want bring it by and I'll listen to it and give you my opinion.

the knocking is constant, it goes faster as the rpm is faster. Sounds like the is going to blow up. I will get in touch with you Patrick as soon as I am able to get time to make a trip up there.

Could also be a spun rod bearing in witch case your pretty screwed....If its a vague tapping like knock then the valves could be out of wack...Or it could be the tentioner as patrick has said

o how did i forget about that.....He's right man your buddies bike wouldn’t be the 1rst cbr hear lately to have this problem.......Its cool though just get it into a shop immediately the reason for putting it in a shop is they have to use a special tool if not you could get hurt replacing it...There not that expensive and you normally have your bike back that day or the next.....

I would say take it to Patrick @ Motorcycles Unlimited. If it is consistent and gets louder as the bike revs you probably have something serious.
