I suggest getting the Ducar 212 instead if the Predator, stronger block, PVL flywheel, 1,700 more rpm in stock form, not much more money.

No video but check out this thread. Probably many more in the Coleman / Baja subforum.

Basically, you just need to mount a clutch with the sprocket inboard on the 212 (to better center the larger engine), align the sprockets, drill the engine plate, bolt the engine down, connect throttle.

I have already have a predator 212 I

That's using an engine swap plate which is how I prefer to do it. SOme like to drill the existing plate. I re-use all of the stock controls and killswitch set up as well. This one used a TAV but a straight clutch/chain is actually easier.

That’s the one I got I have a different model of the doodle bug I want to engine swap it with a predator 212

I drilled the existing plate and had to notch the frame where the rear fender mounts but it can be done. It's a pain in the butt to put gas in it. Been considering a different tank under the seat.

The bar that is behind the engine for the fender mount will need to be bent slightly to the rear to clear the 212 , with rear wheel removed stand the frame up ( ass end on ground ) set a 2x4 across that bar and a couple whacks with a sledge hammer and that will do the trick then you can remount the fender !

Here's a quick video on how a Predator 212 swap was done on your frame.

These frames are made for multiple companies. Some of the other names are:
- Coleman CC100X
- Baja Doodlebug
- Baja Dirtbug
- Massimo MB100

Here’s my CC100X with Predator power. Overall, this is a fairly easy model to swap.

 

[Royalcr]

is a 12 tooth clutch with a 53 split sprocket a good ratio

 

[DaddyJohn]

I like the stock sprocket because I don’t have to spend any more money, and I’m not too concerned about mph. That said, there’s more down low than you need. I’d like to try a 60T…

 

[Strigoi]

No. A 12t clutch with a 60t-65t rear is good.

 

[Royalcr]

I got a 60 already so I’ll be running it stock I’ll see i will run it stock then I’ll change the gearing

 

[Royalcr]

That the clutch I’ll be using

 

[Mark Brooks]

Maxtorque clutches are the Bomb-Diggity for that application.

Maxtorque clutches are the Bomb-Diggity for that application.

They'll also hold up to a lot more power than they're advertised for. I use them for anything that's not an all out build.

bolted right in place of my factory 3hp on cc100x
