79cc or 212cc on a Huffy Cranbrook

I was trying to decide, and went with the 79cc to be safe. I think its possible for the 212cc to fit, but you need the short head unit, and to modify the motor plate

Did you have to modify the frame?

Mezzenger, I've only build about 4 of these things. I'll be honest. If you are going to put a motor on a Cranbrook, be real and don't put anything over 49cc. 79 is honestly pushing it. The bearings, brakes and spokes won't be able to handle all the power and speed. These bikes are cheaply made, so you can cruise the beach while peddling at 5-7 mph MAX. Now, you're going to put a 4 stroke motor (lots of vibrations) and probably crack the frame (happens all the time). Plus, all the bearings are probably going to overheat and seize on you. Plus, the brakes aren't that good. So, I don't know how fast you plan on riding, but 49cc will get you waaayyy faster than you want to go. Going to a 79cc will be pretty close to pushing the limit of the structural integrity of that bike.
If you even think about a 212, either get a good sturdy (stainless or iron or something heavy) that can take that HUUUGGGEEE piston moving up and down...OR... get a scooter or motorcycle. At least they are built for it.
Not trying to be a "Debbie-Downer", but I'm just trying to make sure you live long enough to enjoy your creation.
My 49cc, 66cc and 79cc builds were plenty fast enough for me. Honestly, they were too fast. I went over 35 GPS and was pretty worried (refer to my profile picture if you think I'm a scared little B^%CH, lol). 180HP motorcycles are built for it. These cheap Wal-Mart bikes aren't.

you can put a 212cc on a huffy but you much have 3 hole adapter for rear tire short valve cover and wide cranks put on the rest should be fairly easy as far as mount there is only 2 types of mounting one is flat the other is upright but if your gonna build this ride i hope you weigh at least 200lbs

THIS THREAD is what got me back into the hobby. Predators are kind of a goofy configuration for bike builds, (cylinder slanting backwards), but give credit to The Community.... people have figured out how to rotate and keep them alive, oiling-wise), so Predator 212 in a cruiser frame isn't too far off. I have a Victim in mind, ( a shiny red Cranbrook) , but for now I'm going to go the 97cc Lifan Flatty Route. I'm thinking the deathRow TAV2 is a must- it puts the output sprocket in a more usable position. If I can afford a new Predator, I miiiight eyeball it for the Cranbrook, if the 97cc motor isn't enough.

My first build was a Cranbrook with a 49cc Huasheng engine. The short wheelbase makes for a thrilling ride.
donphantasmo tells like it is but did not elaborate on the Cranbrook brakes fully. Weakest component of the bike. They had a well deserved reputation for braking and locking the wheel. A guy I worked with was limping badly and I asked him what happened "rear wheel locked up". My current ride uses a Worksman rear with a Shimano CB110 coaster hub.

....sooooooo as I'm currently building/destroying the Cranbrook for the Lifan 97cc engine, I did end up getting a shiny new 212 Hemi as a back-up!- Upon looking at the project, some slight butchery of the frame would be necessary for the 212- at least how I want to apply it. My plan, if I go 212,, is to cut the seat-tube and replace it with an engine mount plate, tying the lose ends of the seat tube at the top of the frame and at the bottom bracket.
...but I'll cross that bridge only if if I have to. Right now, all my eggs are in the "Lifan 97cc Basket".

...for sure. There will be MUCH more metal there than before!
This is only if the Lifan proves too gutless.HERE was some previous butchery I did to build my version of a Big Wheel in 2003... it WAS a ladies Schwinn that I hacked and welded to some square tubing. Believe it or not, that joint never cracked or gave me an issue. (The rear axle used to pop loose when I hit the big stuff, but not that frame splice! ?..?
