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.

Iam impressed how mean this thing sounds! 20hp! What most dont realize or understand is what 20hp is like on a small cart or mini bike. My 1000cc ironhead makes 52 and weighs about 850lbs. Never thought of using cerekote on the valves and piston top. Learn something new everyday, Bro-ham I love your channel. Thanks for all the hard work feeding your subscribers killer content every week.

RB, from old guy, from days of Ruppman.
The 70's. This is by far the best tutorial I have ever seen on small engine HP upgrade.
If I only had this in the 70's with the parts, I would have been the coolest kid in my Detroit neighborhood.
Damn good job son. This visual experience will inspire some burgering young gearhead that he "can do it".
Possibly inspiring him enough to stay focused and out of trouble.
Great Job.
God Bless!

Back when I lived in Florida I had a cheap old minibike that my parents bought me for my birthday and it came with a REALLY hard starting 5 HP B&S engine and I ripped it off, my buddy had bought a brand new Sun Racing Engines 26 HP single cylinder engine for his go-kart and never used it, so I bought it from him REAL cheap. I put it on my minibike and that thing was ridiculously fast. I was only like 12 back then and I'm 38 now, but I'll never forget that thing. My mom decided she wanted to ride it back when it had the B&S engine on it and she came FLYING around the house on it and rode it into a row of hedges that we had on the side of our house and straight into a railroad tie that separated our hedges from the empty field next to our house and she got folded. Turns out the throttle got stuck wide open and she couldn't shut it off...lmao

This is a next level build for sure, looks and sounds like a million bucks!

A little advice from 45+ years of building engines. Running bolts dry into aluminum, (or anything, really) like when you checked rod bearing clearance, is asking for trouble - from incorrect torque squeeze to galled threads. It's good practice to fully torque the rod bolt fasteners as few times as possible - meaning, only torque them to full torque on the mockup install to check clearance, and on final install - 20in/lbs is plenty for the installs to check dipper, rod, cam, block clearances, etc. Running them to max torque every time puts unnecessary wear on the threads and stretch cycles on the bolts. You normally don't want to run the ring gaps top/bottom - this puts them on the thrust sides of the block/piston. They seal better and wear less putting the gaps on the sides of the pistons just above or below the pin hole.

Awesome job buddy, I enjoy your all your videos.. I have the Predator 212 hemi. I've got it on a Ct200u-ex. Bought the bike used with engine locked from no oil. Bought the 212 about 2weeks ago and all I've done is mount it. Haven't even rode it yet. I've ordered some upgrades and so far all I've received is my torque converter. Thanks for all your time you give to making sure we the little people know what to do to make our bikes a little better than the rest!

Sounds mean and looks good! My first build blew up a few mins ago and this vid is helping me cope haha.

[spldrong]

Great video!

As a certified mechanic, i would recommend this video

[jayarmijo]

Hey brother I just want to say thank you for your videos, these have helped me purchase the right engine for me and it’s extremely helpful for the builds on the Max Performance I picked up. Awesome work Sir! Thank you again! I’ll continue to share your vids.

[ThatPhilBurgGuy]

I love this step by step build! So informative! This video is sure to get up there in views as im sure anyone building this engine will look to this video for instructions.

[FunKingGarage]

This was a great video! Super helpful to see the actual individual steps without it being a drone on howto. Keep up the great work!

[towboatjeff]

I'm curious how long the coating will last on top of the piston and the inside of the head and valves. Be nice to see ya pull the head after a few hours of run time and see how it's held up.

[randyprater]

Great vid! I could only find two in stock anywhere close to me so I grabbed one today. I think I’ll grab the other one tomorrow after watching this!

[ericfitzpatrick]

I love the amount of horsepower in a small package, and it's rigidity.

[farrismoore]

naw that's like a 25hp or more 💯🔥 that thang is a MONSTER GREAT VIDEO

[rocketscience]

Great Video. 10/10 for technical content, build quality, and video editing. You should teach other youtubers how to make great videos.

[scottjoy]

Another Great Build RBG 👏 Thanks for the Content it's very informative 👍👍

[DarkCornerGarage]

Awesome build. I do a dry run without piston rings and lube to check clearances.

[gr]

Man this stuff is so great to watch I have the money to buy the stuff but just don't have the tools or the time to put them together, with life throwing blows left and right this year I don't even have the time to ride my stock minibike, my downtime I'm working with RBG playing in the background you guys rock!

[Principlesofpleasure]

If your not watching red beard your living under a rock this dude is amazing the best content and details in his videos 🔥💯
