79cc Predator Build Questions

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.

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.

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.

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.
