212cc capable frame?

Excuse me. Would that Macargi Royal chopper bicycle at bike buyers hold up to a HF 212cc engine if the rider is gentle on the throttle?
I believe Sportsman Pat is the originator of the Worksman with the drop loop frame. He uses that (0.090 inches frame tube thickness) with HF 79 and 99cc engines. After learning that held up very well he's working on a honda GC 160cc with peddle start for his peddle cruiser. His bicycles with the HF 212, Honda 200 and 250cc are DOM tubing with 0.12 inches thickness.
It looks like the 212cc engine should be fitted to a very high quality bicycle like a Felt cruiser. Thank you.

Yup. Predator303 built a BEAUTIFUL Micargi Royal with a Predator 212cc.

Does anyone know if a Skyhawk GT-2 frame will fit a Predator 212cc? Seems the only problems would be removing the gas tank (not a problem since the gt2 has a built in gas tank), swapping out for a carb without that huge tall air filter, and getting a better fitting exhaust.
The frame seems like it's a strong frame with a lot of great features (vbrake mounts, disc brake options, rear facing dropouts, build in gas tank, on and on)

Really? Did you not read this previous post?
The Skyhawk frames are not strong as far as motorizing with a high output engine. The aluminum in these frames I consider "soft" for the application.
Go ahead and build one, then you can speak from your experience.......good or bad. Personally I would not consider using this frame for a 212cc build based on the size of the frame alone.......way too small.
All I'm saying is that the same parts fit both engines as far as drive train, carbs/etc. The 79cc predator is cheaper new than the doodlebug engine and makes 25% more power. Now if you've got a used doodlebug engine sitting around and want something to toy around with, be my guest. At a gearing of 12.44:1 with a 26" wheel, it'll get you 32mph but it won't do hills super great, a little better than the china girls do but not much. You can either gear it higher and try to hit every hill running, or gear it lower and lose a little top speed but should climb hills well. But if you're comparing the price of a new engine, the predator will get you more bang for your bucks without spending as many of said bucks. Trust me, I've used the doodlebug engine, I know it's power limits.
