predator 212

Hi all, I've built 2 bikes now so starting to get the hang of engine building but not so much on the frame/roller setup. I'm building a 212 Nonhemi with a mild cam and some port work done, but I want to get a frame that's more of a cruiser and bigger than a CT100U. I've used the ct100u frame...

what is up everyone, I recently started working on an mbx10 that I had from when I was younger. unfortunately, it has sat outside under the elements for the last 8 years and is going to need a complete rebuild. I am currently in the process of removing all of the rust from the frame but I had...

I've got a predator 212 gov removed and some other mods, well I purchased some 18lbs valve springs and as I'm putting the first one on one half of the valve spring locks falls in the engine. Will I have to pull the side cover off to access where the cam and piston in to find it or pull off the head?

Okay guys, so I removed the governor on my predator 212 and put a new aftermarket carb and air intake and it won’t start tried cranking it 15 times. Any suggestions?

Hello all, I purchased a mini bike off market place. The guy didn’t know much about it as he got it in trade for a job he was doing. From research I’ve decided it’s a Baja warrior 200. It has a new predator 212 swapped in it and when I opened the clutch cover I found a torque converter. The...

I recently swapped my stock Jiang dong engine for a predator 212 got everything else hooked up with out a hitch now my charging Coil must not be working because my headlight doesn't come on what could it be.?

For an engine upgrade, the predator 212cc is what most of you recommend right? Bout to swoop one before Cali outlaws em. TIA

Hi there, I have installed a torque converter kit, air intake, and exhaust on my predator 212 for our coleman mini bike. We also installed the new jet into the carburetor (stock) that came with the kit. After the installation we could not get the bike to run unless we had it at full throttle...

Hello, I’m currently building a 212 non hemi and have ran into some issues with my piston to Valve clearance.. I aligned the cam dots and put the side cover on, put in my pushrods and spun the engine over and my piston is hitting the valves, I personally think my pushrods are way too long (...

Hello, I’m building a predator 212 non hemi and need advice on achieving a 10.5 to 1 compression ratio, how much should I shave the head? I haven’t measured how deep the piston is in the hole yet because I already took the whole engine apart and I’m waiting on my ring compressor and other parts...

Good afternoon, Just reaching out for some help for some probably self-inflicted problems. I have a stock predator 212 bike and stupidly leaned it against something unstable. It fell completely over on the air filter side and was there for probably 30 minutes and a ton of oil ran out the carb...
