    96 SLt 780 Carb Questions

    Looking for some knowledge on how to fix a low speed lean condition on a set of Mikuni super bn 38 on my slt 780. So far I have rebuilt them with new needles and seats one step lighter pop off spring (Silver 65 gram) than stock and new diaphrams on all three. Carbs are excellent at speed but will not take off out of the hole without choking to give it fuel. The fuel pump has been checked and rebuilt as well and hoses have been replaced. any suggestion? I am considering just going with another set of carbs to fix the problem.
