Part 1 DUCAR 212 Hemi Performance Engine Build Alternative To The Predator Ghost 212 Kart Engine

This has been Part 1 of the 212 DUCAR Hemi engine Performance build series. If you liked the video, and are enjoying the 212 DUCAR Hemi engine build, you're welcome to join me on the channel if this kind of stuff interests you.

We will disassemble and inspect the internals of the DUCAR 212 Hemi to determine what new performance clone parts will work on the DUCAR 212 Hemi Engine. We'll see what we can use, modify or add to make more power. The DUCAR 212 Hemi engine includes a PVL cast aluminum flywheel. While not billet, these PVL flywheels have been spin tested to 17,000 RPM.

Parts I purchased from EC Carburetors:

DUCAR 212 HEMI Engine with PVL Flywheel: DYNO 212-1000 $219.99

70mm Wildcat 223 Flat Top Piston Kit: Part# 34004-00075-00-K $19.99
This is the Wildcat 223 piston that will work with the Part # 8281 EC Pinnacle 3.353" Billet connecting rod in the DUCAR 212 Hemi block.
I am looking into other piston options that include one with valve reliefs already cut to clear for the 212 DUCAR Hemi head as well so this parts list may change if or when better options become available. You may need to cut or grind some valve pockets on the top of the Wildcat flat top piston for clearance or purchase a piston with the valve pockets already cut as mentioned above. We'll get into clearances and fitting of parts in Part 2.

You'll need to choose your head gasket thickness based on the amount of quench you want for your engine. (The distance between the top of the piston and the bottom of the cylinder head)
Some guys like around .030 to .035 quench, I prefer .020 to .025 on a billet bearing rod / billet crankshaft engine build but on this one I'm probably gonna stick with .035+ due to the Hemi head design and stock crankshaft. Of course like all plans, that may change along the way when or if other or better parts become available.

Tennessee ThunderStix Banzai 265 Race Camshaft Kit, Lifters and 26lb Springs:
Part# TTS-265 $54.99
I like this camshaft. It's not a welded lobe cam so there will be some durability issues if you use heavy valve springs or high ratio rockers. It makes max power around 7500 RPM. With 26lb springs and large enough valves and carb it will spin past 9000 RPM. I don't think the included valve springs will work with the DUCAR 212 Hemi head but I've not gotten to that point yet. The valve springs that come on the DUCAR 212 Hemi look very good (18 LB by the look of them) so I may use those and work with adding an inner spring with special dual spring retainers. It's still early yet and this may change as we get further along in the build.
You can use any clone camshaft (.549-.550 shaft diameter) from mild to wild, it's your choice.

I also purchased a Mongoose 272 camshaft to use in this build and given that I did cut valve reliefs in the piston top I decided to use the Mongoose 272 camshaft as it has more duration and lift then the Banzai 265 camshaft.

Connecting Rod: EC Pinnacle 3.353 Forged Rod with bearing Part# 8281 $79.95

I have verified this Billet rod works with the 70mm Flat top Wildcat piston. The top of the 223 Wildcat piston is .017 below the deck on my block. Be sure to check yours and adjust your gasket thickness to match your chosen quench distance. Deck heights will always be different due to manufacturing so always check your piston to head relationship on every block. Most blocks using this combination will likely place the piston top .015 to .017 down the hole (Below deck). While you could likely use a thin head gasket with this combination, remember this is a Hemi head so some valve reliefs cut into the top of the piston would be a good idea. (I'm looking into more piston and rod options now) The camshaft you choose of course will likely determine how much distance you have between the valve and the piston top too.

EC Rod bearing inserts for Rod: Part# 8394 $17.50 (spare)

Wrist pin specs:
DUCAR 212 Hemi wrist pin diameter .715
Wildcat Piston wrist pin diameter .709

Bore Specs: 70mm
Stroke: 55mm

it dumb not to buy this i cant believe i got 224 and not this thank you good info

I purchased this engine back in February and have only run it on the bench just to confirm that it ran and do a few break in oil changes back when I first got it.. At that time I noticed that the crank seemed to have more side play than what I'm used to. I ended up getting busy with a bunch of other stuff and didn't have time to do anything with the engine until now. So far I have pulled the flywheel and side cover, removed the governor and oil sensor, and I will be starting off what I plan on being a mild build- a MOD2 cam, 26lb valve springs, and a knockoff Mikuni VM22 carb. After pulling the side cover off I can confirm that the crank end play that I originally noticed is coming from the flywheel side bearing. It seems awfully loose to me as well. Have you had a chance to take a closer look at yours? I"d love to get an update on yours if you have one. Thanks for your detailed and informative videos, I have found them very useful so keem em rollin out.

Hi mate top job buddy really looks like a decent engine

[igokarts]

I got some extra karts. We should do a joint build and auction the kart off for charity.

[JBBRAD]

Small clips like that eclip are my worst enemy

[johnpoitevin]

Do you know how those stock connecting rods are as far as durability compared to the rods that come in a Predator? The PVL Flywheel is a great bonus but I guess since these Ducars come already governed at a higher rpm 5500ish? do the ducar stock connecting rods handle those RPM's well?

[heathenprojects]

Waiting on a clutch for my 200 storm my spare ducar going on it stock form I'll be riding my storm this summer plan on buying a ghost to throw on it later I want to do stock comparison between them

[consciouscoma]

so would the ducar work well out of the box for a cycle kart?

[rickwhitfield]

Nice teardown vid! I am curious if you know of any flywheel / coil options to change out on a Ducar 212 or Tilly 212 to get some juice to run a headlight for a mini-bike setup? Someone has surely done it, but i cant find help if they have.

[kyriacosdavis]

The stock piston has valve reliefs in it. Is there any clearance issues with the wildcat piston?

[Apachefog]

I know this is an older video and I should just talk to gopowersports, but I didn't catch if the ducar can use a standard clone connecting rod or not?

[janicefullerton]

Hey my friend! That looks just like my 224 but with a bigger valve cover and different looking fly wheel now I know this is supposed to be more like the hemi version but I would love to know if the fly wheel will fit my 224? And if so who selling it... I did some research of my own and I was told lighter flywheel ✖️ cam = reaching your power band quicker! I know it’s more to do but 60MPH is all I want with a nice mid range power band 💪🏽 would love your opinion on this thanks again awesome video!

[SpACeCruizeRo]

thank u for the info im breaking in my ducar as we speak is it a must to take the motor apart in order to go cruising like its going fine for me so far i feel like im kinda beatin on it a lil any thing i need to do to keep her going strong btw good ass vid

[JBBRAD]

I know you can't get exactly but around what MPH could this Ducar 212 do right out of the box in a mega moto 212?

[curtissmartin]

Are you doing voice over in your videos ?

[jacopodanglars]

i have the ducar 212 and I cant seem to fit any centrifugal clutch. tried several clutch but all are too small.

[Jb_outdooradventures]

??? Will my gas tank from my hisun mount to the predator ghost ???

[SpACeCruizeRo]

so should i get that wildcat piston cuz i just looked at mine thru the plug hole and man its black as hell smh can i clean it before i start it back up after i remove this god forsaken gov gear really a pain in the kisser

[benstolen]

LG stands for life's good. Also the predator ghost is a downgrade from the ducar 212. Ghost comes with a cheap flywheel and the engine block core is thin. Ducar out performs the ghost out of the box as well as you get a better deal over all when you count the high rpm flywheel and racing valve springs. Was excited to get a ghost until I saw one taken apart and realized it's not really a racing motor.

[SeanStratton-vq]

I got. To. The card is it did that barring another site at firewheel bad
