Well, your English is much better than my French will ever be...:-D

As for your problem with the white plugs and bogging at the tell-tale 4000RPM range...if you're sure that your carbs are clean (did you dip them and replace all the o-rings) you've got air leaks... Check all you your connections on the intake boots, at the air box and at the head. Use either WD-40 (RPM's will drop if there are leaks) or starting fluid (RPM's will rise if there are air leaks). One way or the other...you're short on fuel. Also, did you check the float level height? Another common source for a lean bike under load.

Check you fuel petcock...I missed this the first time around. Smell the oil in the crankcase, I'll bet money that it smells like GAS!
