    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.

    well the thing is. i dont wanna buy anything befor i know what and how im gonna do it. as i said im on a very tight budget. and any setback is just gonna result in this project not happening. can u give me a list of things y it might not work out? like if theres a lot of spokes would the sprocket with the kit not fit? and things like drilling in the frame wont be a problem for me. but having to buy extra things to make it work might not be an option for me. so any advice u have at all would be greatly appreciated

    A 4 stroke will give you speed and power, and it wont break down on you every single ride like the chia girl will:-||

    Your China girl kept breaking down because you probably lack the skill to make a good one. With half the hp a 4 stroke should last a lot longer, plus a sissy centrifugal clutch to go with it.

    lol can u guys just stop bickering and help me out? i picked out my motor. 66cc silver slant from kingsmotorbike.com and ppl were saying they got the gt5 motor and not the silver slant so that what im hoping for lol. but my main problem that i can see is that theres 48 spokes and the sprocket most likely wont fit. ppl with the same bike were just using 6 holes in the sprocket instead of 9. which ill probably do but id like someones input. and also someone had said the tanks screws arent long enough to bolt onto the frame. any suggestions?

    Like I said, you'll find out.

    It's not an easy bike and you will be spending extra cash to make it work.

    Parts and labor. The more labor you do the less you will spend in parts.

    Have fun!

    If it is like mine, the studs on the tank weren't long enough. At hardward stores you can find a thing called a coupler. It's like a 1" long nut. You can thread one halfway on the tanks stud, and then you can either screw in a length of all thread, and nut it on, or use the proper sized bolt threaded into the coupling to hold the tank on.

    You can see what I'm talking about in this video at 1:10, and 3:15

    to be honest. i dont think im gonna have to mod anything on the bike to get my motor in there. besides the tank i dont see any issues with it. the 48 spokes will be an issue but problem solved by only using 6 screws instead of 9. and yes mrs. jones i studied!;) lol

    That's the right attitude, I think you'll have fun with few stumbling blocks on this build. I wouldn't hesitate for a second motorizing this big cruiser.......it's basically the same bike as my Black Ale w/29's on it. Piece of cake!

    And yes, I'd throw that p-nut tank in the trash and convert the top tube to a gas tank!

    On some of my bikes I used metal strap doubled up to make new bottom brackets for the tank to screw to. You can bend it by hand yet it's still tough enough to hold the tank on with little problem.

    My 69yr old dad is currently building an Onyx. He's ran into a problem of the grips/throttle fitting the larger handle bars.
