Predator 224 gets billet parts and ratio rockers

Predator 224 gets billet parts and ratio rockers
Installed an ARC billet rod in the Predator 224 powered Coleman CT200U mini bike along with some 1.2 ratio rocker arms and a set of NR racing chrome-moly pushrods. Also did a gear change from a 5 to 1 ratio to a 6 to 1 ratio.

Awesome video once again!! That 224 is a Beast

[@madness_-yg3lw]

Yah it is my manco thunderbird has a 212 on it and turns 8000rpms and goes a top speed of 60mph black is only turning 6500 and is doing 60mph i cant wait to see how fast it will go when hes able to fully unlock the rpms and turn it up past 7k

[@christophermichaels6569]

Pretty cool you’re at 66k subs right now. Congrats dude!

Thanks!

[@charlesgraham9954]

i spoke too soon about not being a money pit. now my grandson wants to do that mod 2 cam and governor removal u did last video. thanks a lot.. lol..! im 53 feeling like a 7 - 8 year old. thank u agian for putting in the money and time to do these videos, so we can pick and choose what we would like to try.

[@madness_-yg3lw]

Please be careful these engines can produce alot of power for a young kid and with no governor the con rod or stock flywheel can brake and become dangerous im all for teaching little kids how to build engines but keep in mind they can get a grown man moving 60mph with a kid half the weight they will go even faster

Great video. You make it look easy. 👍👍👍👍👍👍 Learning alot. Thanks

[@turbocoupe9212]

What ppl aren’t talking about is that the intake and exhaust runners are bigger than the original predator 212 and hemi engine. I bought both the 224cc and the hemi today to do a Frankenstein build but in the process found that the ports where bigger on the 224cc, so I left that alone. They will also appreciate that the factory muffler is bigger than the other 212 predator engines.

[@Black66]

Ya, you have to oblong the holes in the header to make it fit. The head-on the 224 needs some work. It would be better with 5MM valve stems and automotive-style retainers. I want to try my Tillotson head on the 224

[@PopeyesCreeper]

He's not leaning down to reduce wind resistance, this thing would be at 75 if he did. You're not gonna believe this, but I've reached 47 mph with a stage 1 79cc bicycle, completely stock internals and governor still in.

Got the results I wanted on my predator 224 😂 51 mph stock everything tomorrow I’m going to try the air filter only and straight pipe exhaust I got a vm22 mukuni carb but I don’t know if I wanna put it on cuz I feel like my bike is gonna hit 60 with just the air filter and stock carb love the vids thanks for all the help

[@Black66]

What's awesome about this bike is it hit 60 MPH with a 60-tooth rear sprocket! Which makes it quicker. It's more fun to ride now being snappier! Also, it's not so hard on the clutch with the 60 tooth.

[@julianflores2511]

@@Black66 yes cuz I was scared of losing torque cuz I ride a lot on trails but it’s good for both trails and on road thanks alot for all the info 👌✅

[@doodlebug6833]

my personal rule for rotating parts is if there is a need for clearance, use hand tools(atleast finish with). At the rate of speed the rotary tool removes materal and the shape the cut makes me uneasy about future points of fractures. Using a file to square up the clearance surface of the rotating part may save future headache, add a nice finish with a peace of mind. Parts aren't cheap, so i usually do my best to clean edges and save meat so i dont always build, break, repeat .

[@Black66]

I appreciate your personal rule. My personal rule is to clearance it and let it rip! I've been trying to "blow up" an engine on this channel for the better part of a year now . No such luck. I think it would make a great video. I have even started mounting cameras down on the frame to catch the carnage. If it doesn't happen soon I will be re-installing the stock internals to artificially make it happen. I need that video...lol

[@doodlebug6833]

N02 XD, theres the small 16 gram canister kits that tap right in the filter/intake on amazon/ebay. Personally i never added multiple kits to one engine though. Ive wondered, could 2 kits blow up a small motor? If not ,that would be a cool little trick to have a 2 stage nitro kit on a bike or kart. Additionally ive been looking at these 179cc engines by a company called LCT being $49.95 per engine, they seem like a another steal of a deal like when there was the 99$ coupon for a 212s. Anyways keep up the good content and may the motor destroy itself under its own power so we may see that sweet carnage video.

[@Black66]

@@doodlebug6833Thanks! That's is a good video idea! Install one of these on a stock Predator too see how long it lives, or like you said the 179cc. I'll have to look into one of those

[@bma4203]

All those mods for such little gain. Still fun tho

[@Black66]

The half second gain from zero to thirty make a big difference in how the big rides.Its not so hard on the clutch with the 60 tooth sprocket. The best part is, it was faster at top speed with the bigger sprocket. These mods support what I'm doing next.

[@shawn6684]

Is that the stock head that came with 224 ? Mine had the different retainers for valves . Lol

[@prestigemaster6610]

@black66 for these mods do you change the valves? I was going to get a billet parts etc but was confused if i needed new valve/pauhrods?

[@Black66]

The reason I used a different head is because it had automotive style retainers so I could use higher valve spring rates . You can use the stock 224 head with billet parts and a bigger cam .

[@joshhawn3988]

I have 1 Question, Did you use cut to length pushrods or did you order a specific length to go with your ratio rockers?

[@Black66]

I used NR racing pushrods. 5.110 length

[@PopeyesCreeper]

so what do you think this means as far as rods? it seems rods dont fit stock in the 224 afterall? possibly the same with cams according to the guy down below as well? I know little to nothing but maybe only the modified cams fit?

[@Deucealive75]

When billet rods are installed you need to check clearance. Same with the cam. This engine uses clone cams. The guy down below probably is trying the wrong cam. He may be trying a 212 non hemi cam which should not fit.

[@turbocoupe9212]

You got lucky because , I bought the same rod and the oil dipper was hitting the block, I had a lot of clearanceing to do.

My dynocams CL2 won't fit in the 224. The journal on the cam that goes into the flywheel side cover is too large. Or the side cover receptacle in is too small. I have two of these Cl2's and neither will fit. I have not mic'd them but I would say there is about a 32nd visible difference.

How about a better clutch and add a tooth on the clutch sprocket to pick up 0-30 and top speed

[@Black66]

Every tooth you add to the clutch is equivalent to subtracting 6 teeth from the rear sprocket. It would slow it down from zero to thirty. If you watch the entire series I already ran a 50 tooth rear sprocket. It was too much gear for the engine to pull because the engine didn't have enough torque to overcome the tall tires and gain enough RPM to get into the power band of the cam. Check out the series. kzbin.info/www/bejne/panLo6KQn6uVZ6M
