Let us know how many miles each bike gets before their aluminum frames cracked, and where the cracks happened.

212s have been cracking the frames in the same place shown here in the photo. Most builders will beef up the rear section themselves or send it to James at Ghettobike where he completely removes the lower rear section of the frame and replaces it with thick wall 1 1/4” aluminum tubing.

How long do you think it will take before this one cracks when 48hp is put to it, and where?.... I’m guessing too many places to count, haha!

no modification needed
the carb holes are the same as a predator
, the mount holes lined up perfectly and it started up on first pull
and makes more power
the exhaust mount holes are a problem
to fit a predator exhaust i had to slot extend the exhaust flange holes

a predator can be bought with tillotson already on it

If you like the Predator, you'll love our TPP-212H, a high performance, EPA certified engine that offers more torque, acceleration and horsepower Honda GX-200 ...

too had to take off my side plate that the clutch is on and I took out the cam shaft and now I don't know the timing on the thing and can't bet the compression right... Can you send a pic and maby directions on how to get the thing back to running condition so I have compression again... Thank you

With the side cover off, look at the end of the crank, there will be a mark, looks like a spot where a guy wanted to drill a hole but changed his mind. Now look at the cam, there will be a corresponding mark. Turn the crank so the piston is at TDC and the mark is on the right side, slip the cam in there with the marks lined up. You might have to raise the lifters out of your way to get the cam in.

Not sure if posting in right place. But was wondering if a gy6 150 cc could fit in phatmoto all terrain without modding frame
