20+ HP Harbor Freight Engine Build ~ Predator 224cc Max Performance
In today's video I break down the Harbor Freight new 224cc Max Performance Engine, remove the governor and oil sensor, get the engine cerakoted, then completely re build it with performance parts- billet rod, billet flywheel, cut to length push rods, ratio rockers, hot 265 cam, flat top piston, flat slide makuni carb, billet side cover, and billet valve cover- and topped the build off with billet cup washers. I did have to clearance a few minor things. We should see ~20+ hp compared to the original 6.5hp. I put this on my trail master mb200 mini bike.
