Hi,
I have a 1981 Honda CB125T with a 210cc bigbore kit.
I am having some "stuttering" problems when i ride the bike, and it gets worse when the bike gets warmer.
If i ride downhill and "force" the bike past the stuttering it is ok, but if i ride uphill and the engine is under load it will just keep stutter.
It idles fine, the problem only occurs during 3/4 throttle and under load.
Little history: I did not ride the bike that much with original airfilters and exhaust, therefore i do not know if the problem was present then as well.
I have 2 original keihin PD26 carburetors with UNI pod filters.
Also before i installed the big bore kit i had this problem, and i did some experiments with pipes between the airfilter and carburetor, which helped a little bit.
the original airbox is damaged and thrown away so i cant test with that.
With 125cc i had 95 main jets, now i have 110, and i have synchronized the carbs with a vacuum gauge.
Could this be my timing, valve gaps or is it most likely carburetor related?
