9000 RPM Predator 212 cc non-hemi engine performance mods

Time to LEVEL UP your predator 212 cc non-hemi engine from harbor freight with performance mods using budget parts and the right tools for the job!
This video details some less expensive parts, why I chose those parts over alternatives, a few tips and tricks on a performance build for a 212cc non-hemi harbor freight engine, and the tools you would need to do a performance build go kart or mini bike riding engine kit.
The engine used here is a predator 212 which is a 212cc performance engine. This engine build is one of the least expensive builds you can do with your harbor freight engine whether it's for your race kart or a mini bike. I'm using one of these in my race mini bike, one of these predator 212 performance engines will be used in my racing go kart, and one in my race wheelbarrow. This can be considered a stage 3 engine by many and has no part work done to it. You can pick up this harbor freight engine for pretty cheap and I've blown up a couple in testing so it's nice to grab a new one quickly and near me. This is a 6.5 predator engine and the 212cc to hp rank is 6.5hp out of box. When you upgrade your predator motors to a 212 stage 1 you are opening flow. When you add further 212cc predator engine mods with performance parts, you are opening up to a much more powerful engine!
This performance engine build will go on a race kart for oval track dirt track once ready. With the performance carb, most signs I see call this stage 3 build. However, some people call it stage 2, and I even saw one person call this a stage 4 build of which there was only that 1. When you're ready to take your game above the stage 1 mini bike or off road kart engine kits then you can expect to spend at least close to $400 on parts to up your game.

Cresent Wrench is an adjustable Wrench, you have open end or box Wrenches.

[@boonedockjourneyman7979]

That tube extension is called a “snipe” around here. You can get fancy and add a length to the name. People here use electrical conduit. EMT 1/2” x 1’, 3/4” x 2’ and rigid 1” x 3’ are in most guy’s mechanics tool set. Be sure to de-burr the ends. Slipping off is not unheard of when those things come out. I add hockey stick tape to both ends. I sure you can buy it in a minimart where you are.

[@Rossman2003]

Venting the engine can be done without a catch can. You just drill out some hole in your lower valve floor area. Then vent with a one way valve out of your valve cover. Venting the engine prolongs the life of the engine Remember to make them fast and make them last...

Box wrench is that side of the wrench. Crescent wrench is the box wrench that is adjustable with the wheel. You could break that with a cheater bar but you are unlikely to break a standard box wrench.

Hey I bought the predator ghost 212 and the ultra light flywheel didn’t fit . A builder installed a billet non hemi flywheel on it . He said that the engine is a non hemi . Does this make any difference or will it cause problems?

I've found that I can do what I want to do with 6500 rpm, a Juggernaut CVT, and gearing and have a long lasting dependable engine that'll last for years. 55 mph on a 135 lb. minibike is plenty fast enough for me and no clearancing is involved with dropping an EC Carburetors .265 Bansai cam into a Ducar 212/Tillotson 212E block with a billet rod.

The pipe you're using for extra leverage is generally called a cheater pipe. Could be other names for it but that is what I've always heard people in my area call it.

[@MoneymanRome]

Really interesting on how you mounted your catch can, I have the same exact one. Does it make a difference running it how you did rather than how it’s supposed to be?

[@megoingfast]

Most would buy an adapter/lift for the valve cover and run the line from the crank case to the valve cover and then into the catch can - but I swap engines frequently. This keeps it all contained in one place for demo purposes.

[@MoneymanRome]

[@ethanduke813]

@@MoneymanRome is there a how to on mounting it or you just went off how it looks?

[@MoneymanRome]

@@ethanduke813 I have a video on my channel with how I mounted it, you can either tap the governor hole for a relief with a hose going to the valve cover and then a hose from the valve cover to the can, or you can tap the side cover or get the billet side cover and do the same thing. It helps a lot for cams with higher spring pressure to relieve the block. I cracked my first 2 blocks not knowing it.

Not sure what you're talking about. I'm thinking I put the video together wrong or people are not watching it the whole way through. I shimmed the springs like stated in the video, works great. I've made more than just the 1 of these. This was made after running these guys. This is a base for a larger build and information on how to build higher output engines. Shows part names, list, tools, etc. Build ideas, etc.

@@Toid makes sense. I made the video to answer people's questions they were asking me about what tools and names of parts to use when going above stage 1. Guess I really just stopped after answering the questions.

Drum clutch the hilliard inferno fire can take some power but getting sprockets is a little difficult. Best for most mini bike applications. For disc clutch The gofasthp.com clutches are hand made and you can get help for your build. Actually may be able to get help and the right parts for either setup. Last clutch I bought from them, best prices out there other than a 2 disc from childishconcepts.com which is also a great place for help on a specific build.

[@ryleecardona4741]

i’m not sure if your going to see this but can you please do a parts break down video of everything to chose to have the most power for a predator 212cc non hemi engine cause i want to do the stage 4 kit but idk what to chose and there’s no video talking about this

[@megoingfast]

Most power bored and stroked with welded billet head running on alcohol can run $3000 and get you 30hp. Once you hit stage 4 you have a lot of options to take it past the 20 hp limit, however these crank cases usually blow up at 25hp and need a lot of reinforcement. If you're looking at stage 4, the crank case from a tillotson 212r is much more recommended once at this level. Most all power upgrades for that build are custom fabrication and metal manipulation.

[@megoingfast]

For a purchased kit build, Red Beards Garage KZbin channel has a build video. You will likely need to further research high compression heads, balancing your crankshaft, boring and stroking the engine, and port work on top of that. It's a lot more work than just 1 video. 😉

[@ayolz1588]

Hey man, I am doing a complete rebuild for the same exact engine and decided to do this build. I was making my list and at around 4:19 you said a part that I couldn't make out very well. It was right before the spark plug. If you get to this, could you let me know which part it is and possibly give me any advice on the overall performance and experience with this build? Thanks

[@megoingfast]

7/16" bolt, for tapping into the oil sensor hole. The engine has pretty good performance, and is a setup for some pretty decent power as is - that you can take even further to stage 4 level with balancing the crank, honing the cylinder, porting and polishing the head and a few other steps. The cs grind cam is a 265 lift cam similar to the popular cm grind and hot 265. If you do not shim 22lb springs, you can change to 26lb. This is a fast build that is inexpensive that kicks out power giving a great engine build experience. The catch can can does not have to be bolted to the engine, that just made it easier to contain for me. Many people prefer to buy a spacer for the valve cover and run the crank case vent into the spacer. Jet size will vary on a few things, you may want to run between 120-135, depending so having a kit helps.

[@ayolz1588]
