So its worth getting? It will make a difference in speed right? Cause im gonna get it if it will work
It won't make it any faster. It'll give it a 1 or 2hp maybe.
Speed is gearing and rpm.
If you want to add more speed and power add a torque convertor.
Stage 1 and torque convertor with the throttle stop screw removed it'll go 34 and climb pretty much any thing I throw it at. I hit a 5 foot nearly vertical hill with it and shot right up it. Although the flat landing at the top hurt a bit. A friend thought he was all bad hitting hills on his dirt bike so I had to follow him. He didn't go up anything I couldn't.
Adding rpm safely is more expensive. You'll need valve springs, rod, cam and flywheel upgrades. 250ish dollars.
