Re: Parts that should be replaced before installing the kit
dude, i'm not going to argue about it.
those pics you posted are not from stock motor mounts. @ least none i got. i didn't get one single u-bolt.
the stock little cast aluminium pieces broke. 2 of them. i don't see one pic in your photos that show the mounts i was sent.
i replaced them with with something strong & now no problems.
i could go outside now & keep tightening till either the bolts break or my steel frame kinks.
in fact i bought a whole bike & engine together as a kit from spooky tooth. the only way i would have been able to mount my front oversized tube is by drilling the frame.
i didn't drill.
