The profile of the stock jet is similar except for right off idle where it is a lot more tapered and thin and will be much richer. I would FIRST try and call the Dynojet folks and see if they have anything to say. They will probably tell you to try the 2nd or 3rd slot on their jet needle. If you don't get any good info from them or have already tried what they suggest, try your stock jet needles again... If they are a bit lean, then order some Mikuni jet needle shims and put 2 each under the e-clips. To order, contact
www.z1enterprises.com - You could try some washers from the hardware but I suspect they are not made to the same tolerances. Keep us posted!
One last thought... I am not real sure if you have baffles in your pipes or not... is the muffler part just hollow or do you see a smaller tube running down through the inside. A LOT of folks think they have straight mufflers but they are indeed having baffles. If you don't have baffles, you might want to get some and try that...
