First, this is considered a improved stock. Next determine the pipe
RPM. The stock gears may work if the pipes are tuned for 9200. Try an Erlanson silver primary spring and 48-52 gram weights to get your pipe RPM. try a 58/52 58/50 helix with the yellow spring. Then test and keep record of all your changes and what they do.
