[@RyanCusterKWC]

Nice Video, thanks for sharing!

[@casycasy5199]

wish you filmed it in real time

[@PlayerOne306]

Need to find your weak link and find the magic in the chain and you will get a lot more too speed especially with that new engine swap

[@eb5864]

How did you get the electrical wiring to work from the snowmobile to the motor

[@TubThumper6969]

Moral of the story, be this father . And your boys will stay boys. Lol Love it, these kids are growing up how I did

[@mrquickspool]

Did you need any other parts concerning bolting the engine in or just drill new holes and bolt it in(for both the pan and the side mounting holes)?

[@coreychenette2414]

No other parts needed. Just drilled new holes and bolted bottom and side.

[@Dust5d]

What did you do for the intake? I can’t figure out what to do for it to fit in there with some sort of a filter before the carb

[@coreychenette2414]

No filter, wide open. The original motor had an 'upgraded' velocity stack on it that I transferred over. It looked like a little stainless steal doughnut 1 inch spacer. I just plug it up over summer so mice don't get in there. It's not going through deep powder and is facing rearward, so not much is getting in there. I thought of putting some kind of cheese cloth or light breathable fabric over it but never did.

[@MNSHT_MLAIR]

there is no point in this exept for replacing a blown factory motor. if you try and make it faster from the motor it breaks the chocks that run the track. if you do gearing it stresses the frame too much and bends. not the best idea unless for racing.

[@coreychenette2414]

Yup, original engine seized.

[@PlayerOne306]

Lots of people have been swapping engines on other snow mobiles for years this is no issue to add a little power to a small snowmobile

[@GOONRID3RFRANKLIN]

Did you use a standard "go kart style" clutch??

[@coreychenette2414]

Yup, typical hilliard style clutch.

[@larrytemen4789]

Size wise, how much bigger is it than the 123cc?

[@coreychenette2414]

The displacement difference from a 120cc to a 212cc is 92cc. The physical size of the motor in the pan is not too much larger. It is orientated a bit different, but not too far off.

[@OttValleyBoy]

What did you do to the throttle to get it to work with the factory cable?

[@coreychenette2414]

I used a bracket off of the original motor to hold the cable sheathing and screwed the cable into a Philips screw on the throttle control arm of the predator. I can get a pic or more specifics when I take it out for the season.

[@OttValleyBoy]

@@coreychenette2414 Sounds good, no need for a pic. My next question is what did you do for a muffler?

[@coreychenette2414]

@@OttValleyBoy I used a combo of the original exhaust down pipe and predator 212 muffler. Welded the two together, had to add some scrap curves to make it to the hole through the plastic in the bottom of the pan.
