Well, I pulled jug, and grooved from main intake to bottom of skirt. I also opened a window on bottom lip of skirt. This has really helped the Arrow reed, and the engines lower case circulation. Bike now has even better torque, and has even made reed produce more power at lower RPM's!! This all is happening even while using the same fixed 44t sprocket. I'm sure that if I stuffed lower case of engine, I would even see better results.
Also, I trimmed thinner the bottom of the two transfer ports of jug.
Pleased...................
