    Hey Everyone

    Nice to make my introduction. I've been lurking for some time so I figured I should go ahead and start posting. I live around in the foothills/Piedmont of North Carolina. Already have one build of a Nel Lusso with a Predator 79cc that I toy around with. I've always had a boneyard of old...

    Fito Modena GT-2 Questions

    I have questions about the Fito Modena GT-2 Beach Cruiser Bike. It is advertised as a 26" Mens Beach Cruiser Bike But the wheels are listed as Kenda 24"X3" high profile wide tire. tire diameter: 26". Would a standard 26" wheel work? I am thinking about reusing my mag rims with 2.5" tires. Do...

    Primary reduction and clutch question

    I am looking for a primary drive reduction for the 79cc Predator. I am finding some that have a plate that bolts to the engine around the 5/8" output shaft but do not know which ones are more reliable. Is the Max-Torque clutch the one to get? I am seeing several others, some that are tuneable...

    212cc Predator Experiment - Performance Build

    So I'm thinking about building up a 212cc predator engine with the goal of getting as much power as possible on a $1,000 budget, not including the stock engine or a bike to put it on, as I have both of those already. The end goal would be to race it in the unlimited class at one of the SoCal MB...

    EZ Q-Matic for 79cc Predator

    Is the EZ Q-Matic for 79cc Predator any better than the jack shaft setup you see in the 79cc Predator kits? I found a video of a EZ Q-Matic and 79cc Predator on youtube. The video is very short and tells you very little.

    Predator 212 custom fat tire build

    Lots of work into this build for shiny side up 2017 and is a late post but I finally got some time to put it up here. As for the build : I custom made the fat tire bike frame from customizing a mongoose fat tire bike. I customized a girvin linkage fork by widening it out to fit 4" rim and had to...

    Predator 212 Mod Help

    So I just bought two Harbor Freight Predator 212cc engines, one for a mini bike and another for a go kart. I am planning on performing several mods, such as governor removal, air filter and header upgrade, etc. I just wanted to know, after removing the governor, since the engine isn't optimized...

    Hey folks, its been awhile since I've been on the forums but I have some news! After selling my motorcycle I started a new motorbike project! My other builds were with the China Girl 2 strokes and I wanted to move up in the world so I decided on a Predator 212cc engine. My friend and I went...

    Predator vs Other Brands?

    I am thinking of building a motorized kicksled with a 4-stroke engine. I have searched a bit and found out that the 212cc Predator is much more cheap than other engines with 6,5hp, and now i wonder why that? What do you think about Predator engines? Do they have good sustainability? How are they...

    79cc Predator Flywheel Upgrade?

    My flywheel failed catastrophically today, destroyed itself, the magneto, the blower, the housing, and to top it all off, broke the engine block itself. I have heard mention of billet flywheels before but I can't seem to find one anywhere. Can someone point me to somewhere I might be able to...

    New guy in Illinois.

    Hey all. Working on my first build and using a 79cc Predator. Not sure about gearing. Was thinking about using a direct drive 10/62 combo but also thinking about jackshaft with a 10/22/9/? setup. Just don't know what sprocket to use on the wheel to get me to around 40-45 mph. This will be a...

    2 speed 79cc predator build

    After building a few 79cc predator bikes for friends of mine and having them turn out far better than the first one I built for myself, I want to have the best bike again, so I'm starting a new build on an old trek 820 with a 21" frame that I got off craigslist for $150. I figure I'll keep my...

    79cc Predator Build Progress

    So I'm replacing the 66cc chinagirl on my bike with a 79cc predator because I got tired of the chinagirl breaking down every 3 weeks. Some people said they want to follow this build so I'm making a new thread in the proper location on it. Here's the pics so far, as you can see, the engine barely...

    Want to swap 66cc 2 stroke for 79cc predator. Any and all advice welcome!

    So yea, my 66cc chinagirl engine breaks like clockwork every 3 weeks or so, never the same thing twice, but always something new to fix, and I'm sick of it. Plus it's really underpowered and has no hill climbing power and (at least in my opinion) pretty mediocre speed. So, I want to swap it out...

    First 79cc Predator Build

    Hello, first time posting here, and apologize as I am sure some of the questions I am about to ask have been asked before.. I have built 3 different China girl kits (as I am seeing them referred to here) on three different bike styles, the one where you buy the whole kit and essentially bolt it...

    HF 212cc capable reverse gearbox?

    I'm mounting a HF 212cc Predator with the crank facing right, and I need to reverse the PTO. The engine must be mounted this way, or I'll have to do some serious hackery to the frame, which I would really prefer not to do (I don't have the proper tools to fit the frame for left crank facing...
