    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 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...

    I need to know what spark plug would be a good replacement.

    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...

    Sixty-seven fifty, a 79 Predator/Qmatic build

    Hi all, it has been a long time since my last post, and quite a while I have built anything other than Whizzers, both Vintage, and New Edition. It had come to my attention that a 79cc Predator could be made to run at a similar level, and with similar results as a 1946 Whizzer H-motor kit bike. I...

    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?

    Well, I just finished mounting a new 79cc HF engine on my bike. I bought a new engine back in May of 2016.
