its gotta be coming from the head if its in the cylinder. maybe you pinched an oring during the install.

12mm cub? you mean 10mm cub? not that a 12mm cant be done, but its just not a common setup. the 10mm cub is a very common setup with parts readily available.
i think on gas theyll make about 110hp.
steel. primary drive sprockets from rmatv are cheap and durable. alf44 here on hq is a dealer for them and can get them for you. i recommend replacing the rear and getting a new chain too.
take a grinder and grind off the rivets off one side of a link. then take a hammer and screwdriver and drive off side of the link that you ground the rivets from.
i see whats going on here and honestly i dont care. what someone does with a frame AFTER they buy it from Ray is their business. i advise that they at least look into local laws so they are educated somewhat on the process and such.
i havent seen anything special about them that would make me believe they are any better than any other razr tire. just another gimmick tire by a company that makes shitty tires.
jeremy, welcome to HQ bro
i would PM "NYUK" here on HQ. he parts bikes all the time and will probably have any and all parts you might need. one stop shop and he is a super good guy to deal with.
