In 05 I put a S/E 6-speed, HTCC heads, 510 gear drive cams w/big bore on a new 05 Ultra and the customer still wanted more, S/E made a race set up for the primary, it was a smaller comp sprocket and a new primary chain, well that did it, he was happy and had one of the fastest Ultra's around. He came in my shop last week and said take the race kit out of the primary, he's getting older and the power isn't as important as it was and wanted better gas mileage with lower rpm's on the interstate, well he came in this morning and said what a dog his bike is now, wants the race kit put back in his primary LOL I think we've all been their, why did I do that??????
