Hi there,
I am planning to build a 79cc bike, but I am confused about where I should begin to get parts.

I know that GasBike.net sells a kit, but I have heard and seen terrible reviews of their shipping and customer service policies, and how their jackshafts and transmissions always seem to show up broken.

I am wondering if anyone could give some recommendations on parts I could gather from hardware stores, amazon, etc, instead of a kit. I am also concerned that the BBR mag wheels I plan to use won't hold up to the extra torque and speed. Any advice I can get would be great.

Gotdam,
Welcome to the Forum, in the motoredbike it really is all about the $$$. Quality parts are necessary for safe and reliable builds. For wheels Worksman is the gold standard and they have versions with aluminum rims. Easiest way to purchase those is https://sportsmanflyer.com/shop/parts/4136cssal-rear-wheel-shimano-110-aluminum/.
The rest can best be sourced from https://mbrebel.com/.
Lynn doesn't peddle crap. She is honest and knowledgeable. Many of her products are USA made in Wisconsin.
I am currently building a Sportsman Flyer 80 that uses the HF 79cc engine.
https://affordablegokarts.com/ has lots of info and performance products to enhance the HF79.

Hi I'm new here I bought gasbike's transmission and I agree they aren't the best they don't include packing slips but they are cheaper than bikeberry on some stuff. I put a 79cc predator on a bike called the micargi predator it's a stretched beach cruiser. On my bike I have a mag wheel the hy22 or whatever it's called on the front with a disc brake and the rear wheel has heavy gauge spokes and a sprocket adapter. The wheels you have should hold up the bearings could eventually go though I'm using Italian made #415 from Regina chain instead of China chain.

Cool. Thanks for the reply. I have emailed MBRebel with questions but was not able to get a response. Also, I am in Canada so hopefully the sites you recommended ship there. I have also seen that AGK says it is permanently closed on its google maps image, but I will see what I can do.

Ya I heard she has some good parts I just rode my bike and it has a problem where I think the clutch is slipping or the shaft has a slight bend, because theres alot of chatter and I also have to pedal so the engine can take over it will go about 30ish on a flat but where I live its mostly hills and if its a slight hill and I hit the gas without pedaling the bike just vibrates and barely moves. The governor is a pain too. Maybe I'd get more power if I chopped the muffler off my pipe. My chain alignment isn't perfect either. I'm thinking of getting a used honda ruckus.
 
Ya and they go 40-45 and still are 49cc as well as street legal and I dont think you need a motorcycle license to ride one. I could be wrong though but something that could actually keep up to traffic and not going 25 everywhere and not needing a class m would be nice.
 
I've seen quite a few used rukuses on Craigslist and every time I feel so tempted to just get one, they are cool bikes! Apparently relatively easy to work on and mod too.
Scooters are fine but there is nothing to grip your knees on. A lot of older British motorcycles mounted rubber pads on the gas tank for more control.

Wish I still had my M, a DMV screw-up lost it and that's when I stopped riding my BMW R80/7.
