I retapped the holes in the case to 1/4 20 using a bottoming tap to use the entire bolt hole, the Chinese for some reason only favor the first half. Just cant see using those crappy combo screws to hold the case together. I can torque these.
I guess this engine with wider gear and cover will be something else we have to watch out for now....

Oh yeah, the holes do tap out nicely with a 1/4x 20 Ive done mounting stud holes with it on one of my engines, works great and gives a larger strong hold or stud.
I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
