    Did I ever show you all how clean my 212cc predator build came together?

    About a year ago I needed to build a tough off roader bike in order to support my true passion hobby of exploring abandoned mines, many of which have derelict roads/paths leading to them perfect for motorized biking. My goal was to create a simple and lightweight off-road bike with lots of...

    Gas and brake pedal

    So here's an idea. Most older motorcycles have a foot brake. What if i were able to attach another pedal next to that brake and wire it to the carb, creating a gas pedal? Aside from being a bit wider, i think it would work pretty well. What are your thoughts?

    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...

    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...

    4hp briggs cruiser project

    We finally hit a break in the weather in upstate New York, so I took the opportunity to work on my btr/powerplus bike. This bike originally started out as a sportsman flyer with a cheap china girl slapped on, but I soon realized that it just wasn't doing the bike justice. I ripped out the old...

    In need of a belt drive shifter

    Hey guys, I'm looking for a shifter similar to what you would see in indian powerpluses or very old belt driven harleys. Arien snowblowers have a nice speed shifter but there are none for sale cheap near me. I live in new York's capitol region. If you have one please let me know.

    Magneto coil for 79 Pred

    I need a spare! Anyone know where I could go to shop for something like this? Hopefully my description was enough. It would be nice if replacement parts were more readily available... Thanks, -Michael

    79cc Pred No start.

    Got the bike put together. No start. I'm afraid I could have messed up the timing when I removed the governor. ... Basically I was spinning the motor and the cam gear was lifted up enough to not spin the drive gear... I aligned the timing marks not really knowing how long that gear was...

    Monster 80 79cc Spark Plug?

    I need to know what spark plug would be a good replacement. Kings motor bikes has the absolute worst customer service, (and i'm a repeat customer) even going out of their way to be jerks about my tracking info then ignoring my emails, then being jerks again by sending links to two stroke videos...

    I want to install a suicide clutch on my 79cc predator build

    I love the 1910 era of bikes. Board track racers are my favorite and I plan on revamping my existing BTR build to a more authentic style with a 79cc predator engine and proper clutch system. In addition to the engine swap, I want to try my hand at installing a suicide shift (pulley clutch). As...

    Suicide shifter on 79cc predator

    Hi all, long time lurker and builder here. I plan on upgrading my boardie from a chinakit to a 79cc or 212cc predator. I love the old suicide shifters and was hoping to implement one into my build. Is there any replacement for the centrifugal clutch so i can just run a pulley wheel and shifter?

    Installing generator to a predator motor to power lights

    I watched this video, but I had no sense of how to apply this to a 79cc Predator because it lacked details in the comments section. Has anyone attempted this mod?

    Quiet Exhaust for 4-Stroke Predator 79cc

    My bike is loud! It has a short pipe with a screw-on B&S knock-off. Attracting attention is NOT what I want to be doing. I need to make it quieter. The two options I'm considering are: 1) Lifan Honda CT70 clone or 2) 38mm for 125cc-160cc Dirt or Pit Bike pipe Are there any issues I...
