I need some info on my bike.I cleaned my carbs broke all the old gas build up and got new needle seeds for it but it still runs but like %!ยค. I have new spark plugs on it. what els could it be and I changed my oil and filter. Nyway when I ride it it will kind of not respond to my throttle if i juice it all the way it will try to die out but wont and if i just speed up steadily it will run fine. then my other problem is one it is old bike but its my project always wanted a bike,and my gas tank has rust on the inside how do I fix that?then sometimes when I try to start it it wont so I have to juice it all the way for to start and I for got but I have to turn my choke on when im stopped for it to keep on running that or rev it up alott if any one could give me a lesson or two to get this poor bike another life I would like to hear from you thanks alott.and peace to all.
