As is the case with any power upgrade, it is important that you make adjustments to the carburation as necessary. The dyno graph shown had the jetting adjusted one size leaner on the main jet and one clip richer on the needle for optimum performance. However, you will need to adjust your bike’s settings according to your ambient condition. If in doubt, start with a rich setting across the range, and lean off as required. Failure to correctly set up the carburation could result in engine damage.
