After all the funny stuff, i am sorry to say that the bike still does noto run right
Starts easy, no stalling, warking pretty much perfect at idle. Low range is nice up to 5k.
Removed the carbs again and found that the front carb choke was stuck open, closed it and and tried the bike again. The one of the two small carb vent filters that are in the air box was torn apart, so i change is with some foam, and put samo ot the other too. balanced the carbs again too(this time with the air box on).
Better performance but still not best. The tach is smooth to 6-7k then the bike hesitates a little, then goes to 8-9k ant i can feel power, but as i change the gear and the rpm drok to 7k there is hesitation again, just for a second and the bike pulls again. The bike did 210km/h that way, feeling the hesitatino each time i changed the gear, and i run out of road.
May be just result of riding 20km with front choke open, may be not.
One other thing - the big popping from the exhausts when deaccelerating is back. I had it before the cct failure. At that time i though it was because the link pipes and the cans are not connected well, there is 5mm space. Then when i stipped the bike to get the front head fixed i noticed the rear cylinder vacuum line was left free, not connected to the pet rock, and thought that it was causing the popping, because when i started the bike after cct fix the popping was gone.
Well now it is back and i do not know if it is for good - on one hand before the cct failure the bike was poppong but runing well, on the other the popping is no good and my be result of lean mixture, moreover now the vacuum line is in place.
Any suggestions?What could cause this hesitation at 7k?
Can it be blocked fuel cap vent?
Can it be the foam i put on the carb vent holes(those in the air box, under the air filter)?
Lean mixture or not properly tuned carb for the fixed front head?
Something else?
