So i just order the genisis onyx from walmart. Ill posting some pics of the bike when i get it. Its a huge beast With some 29' tires. I really wanna put a 2 stroke grubee gt5 motor on it. But because its such a big bike a was wondering if it would even fit. And what kinda modifications i would have to do to it. I should also add that im on a tight budget. Any suggestions or added info would be greatly appreciated.
