one simple question

thanks for the answer Big Rich, yes it did run before the cleaning. No offense taken for the choke adjustment. I couldn't use the choke before, the cable seemed to be stuck somewhere (perhaps it just need grease, but the bike  - before the cleaning - started without needing choke) and i did'nt do anything to fix it this time. so most of my attempts where without choke (except for some that i pulled with my hands the choke slide on the carbs). I'll check for your tips and pray!!!

hurray!!!!  
Everything (that has to do with the carbs and engine) is settled OK! I wouldn't have managed it without the help of some neighbors though...
The thing is that the engine wouldn't start after my carb cleaning. It did once fire up when i was trying to find whether there was spark in it. So it fired up only on one cylinder. I put the spark plug back in, it fired up again, but then i tried to lower the rpms and it died and never woke up. shaZam!...
After some time the neighbor suggested i open the carb bowls to see if there was fuel in them. The right did have fuel in, the left didn't (it was the left spark plug i had pulled out when the engine started on the right cylinder),.

So we took the left bowl apart and saw that the float needle was stuck in where it was supposed to move freely. I cleaned the place thoroughly, put everything back on, and there was gas in. The bike did fire up, but again only on one  - right - cylinder. Wtf, i said. After swapping the electro-things (that are one for each cylinder and look like black barrels and bolt to the front of the frame   ), the other neighboor suggested we pour some gas at the air intake of the carbs to see if the problem was still in the carbs. Pouring fuel in did get the left cylinder running so nothing electric -pheeew, just the f@@@ing carb. I disassembled it and the other neighbor cleaned it so i could watch. He did a great job with the carb cleaner showing me where to spray and where to wait for the liquid to fell off and to prove that the specific opening was truly open. Finally there was one small jet stuck (yes I know I'm an ass for not cleaning it, I thought it was ok and was afraid to pour carb cleaner in there as i didn't know if there was any o-ring and stuff - btw the neighbor didn't show any respect concerning the use of the carb cleaner, with the bowl open and the floats out he sprayed almost everywhere).

I put the carb back in and it worked as a dream!!!
No knocking or other freaky sounds so the deal ought to have been as zirconx and JAY W had assumed, knocking because of the one cylider that didn't work.

Thanks a lot guys!!
Now it's time for the fork seals as t looses oil one the disc brake 
mmm let's see, is there any neighbor left?

yay for the solution! 

but just a humorous observation .. to many threads .. the titles usually say something like this one ... but the thread content never stays as the one simple  question
