With my new cam my engine pulls hard around 4500rpm and up. With the high gears I now have, 2:76, by the 1/4 mile its just starting to unwind. I need to go with some lower gears either 3:55 or 3:73. Since I do alot of riding in the summer and will be doing some 1/8 and 1/4 mile racing, which would be a better all around gear?
