Upgraded motor mount studs to m8

[mrbg]

Hey I just got a new motor and I see they've bumped up the size of the motor mount studs, when did that happen?

I think late 2017 the larger stud engines were coming out and addressed one of the commoner problems ppl were having with studs pulling out, breaking, stripping and with wider posts and tubes in the more modern bikes, a bigger stud made it more secure and ppl were overall little happier with 'em so majority of them made now are 8mm w/wider mount. many sellers list this as a selling point now I see.

Ya, I'm glad they finally got around to doing that especially now that they have a lot of people selling hopped up motors. Me I just leave em stock,25 mph is fast enough for me.

My pk80 type has the bigger studs goes 37 stock with end cap off. I didn’t believe people before I got one of the 40mm instead of 38mm motors.

pretty soon they'll all be 40mm stroke, but I wish they'd clean up the castings. they always just look so rough.
next 2 stroke I get I think I want a triple 40
