Excellent power increase (26mm carb) and easy to start out of the box (no remapping). Relatively easy installation using a Nibbi intake manifold adapter and an angled Nibbi air cleaner. Initially, everything was stock, due to space limitations, the air filter was not installed directly, and there was a minimal gap between the frame and the throttle cable at the top of the carburetor. I milled the two intake manifold flanges to change the angle slightly, only removing a small amount of material on the back and bottom of the intake manifold flanges (although this would be possible on a belt sander), causing the carburetor to rotate. /airfilter down 3 or 4 degrees for a perfect fit. Needed two new hardware store fasteners for the intake manifold adapter. My only complaint is that the spool return spring is weak and the throttle is quite jittery and touchy at high torque (a lot). This leads to hard grip issues on rough terrain. I'll try to use a spring from the original carburettor, it's much stiffer.
