If you check under "performance mods" there is a big section on on shiming the needle jet and changing main jet.I rejeted my bike and find a big difference in performance.The G.Z. and the S40 have very similar carbs. |
I have read up on the performance mods but didn't see anything about just adjusting the carb screws without rejetting. If just adjusting the screws on the S40 improves performance as well as people are saying, would it do the same for the GZ?
