Not sure of your options from here.
But if you are thinking of an aftermarket primary.
I tried the the PB80 for my nytro xtx and really liked it.
Simple to use, very quiet and performed just as good if not better than the stock yammie primary.
You likely could mod a Nytro to work very well.
And since the resale value of the Nytro is going down faster than JB.
There are some picking up Nytro's for around 5g's many of them with spares galore.
Thrown in a few more G's and you got a very accomplished snowmobile.
Could all be done for...
Have a look at the 2013 XTX coil spring holders.
I'm sure Yamaha has updated them again.
This time with a steel cap colser to the spring over the top so you can't rotate them.
Nor could a spring accidentally pop out of one of them.
It's always good to check stuff over.
Same thing happened to my 08 model.
After 3000 miles I couldn't take one hand off the bars going down a road. Almost flipped it once adjusting my visor.
It was the plastic arm bushings and crappy lower ball joints Yamaha used back then.

You must be looking at it wrong.
Look at how many seasons you rode and take off approx $1500 for each year.
Then you get close to what your sled is really worth.
Anything higher than that is a bonus.
Kinda like a cheap rental.
I really like my Nytro.
Still on the fence if I should sell it or let the wife ride it.
There is no reason that I couldn't keep it.
Other than Yamaha should have some new cool stuff coming down the pipeline soon enough.
Going to try out Doo for a couple seasons.
XS 800 etec R-motion, light sled.
Waiting for Viper to get a year or so sorted.
Would also like to see if the rumors are true about 5 new Yamaha engines over the next few years.
Well it's time to move on to something new.
My 09 xtx has served me well.
Never once did it leave me stranded on a trail.
Will miss all the fun I had wrenching on it.
But most of all the motor.
All the extras I have for Nytro will be up for sale here on TY soon.
Cheers
Vent each side panel behind the front shocks.
Cools clutch and belt on left and cools oil tank on right.
The vent that made the most impact were a hole on each side right behind the radiator.
I pulled the tuning fork emblems off and used a hole saw perfect spot.
Had a temp gauge and watched...
Same type (brand) they use on the new Indy 600, but for a Nytro.
Before everyone calls me a traitor... What could possibly be wrong with a Yamaha primary? Not much really.
The PB80 is quiet, really easy to tune, smooth from early engagement to top and is cut better for closer to overdrive...
Here is the dyno test from 2 years ago.

Since that time Hurricane has developed better.
I've since switched to using the DB reducer to help with the longer rides.
Did some serious tuning with clutches. Love the primary I'm using.
Was never on...
