I recently bought a used reconditioned, Honda CB400 Super Four (NC31) Year 1999 Motorcycle and now it has a fuel overflow problem. Carburetor needles that have are shorter than it should be(the black head thing on the needle value wont fit compltetly).
Can anyone tell me what is the exact type of needle to use on the carburetors to fix this issue, i tried cb250f ones, and didnt work.
Please help me to overcome this problem.
Thanks a lot… :) :) :)
