NyPro project a GO!

snopromod · Mar 8, 2013

Sold my motor, and found a used nytro for motor swap. Will be selling nytro chassis as a whole minus motor and electrical. Looking for $1750 for everything!

I will be updating you with pics of build and issues or good ideas that come about. Adrenaline Junkies will be doing fab work in Deadwood, SD they do amzing work and very knowledgeable on Yamaha motors! Stay tuned for updates....

Damm wish you were closer. I would grab that nytro chaiss for spare parts I need.

Dry fitted nytro motor last night in pro chassis, everything seems to fit except steering linkage, looks good sitting in there wish it was done so i could try it out! Weighed my 600pro motor with primary clutch 95lbs. / nytro motor with primary clutch weighed 125lbs. If my figures are right we should be on par for a 490lb. 4 stroke, full of oil and coolant, ready to ride!

Did you weigh both the Yamaha and Polaris rolling chassis?
I would be courious to know those weights as well.

How are you coming up with 490 besides the weight of the nytro motor and clutch combo?

By the time we add the oil resevoir, and the fluids that should be pretty darn close

Here are some pics of the dry fit, as you can see the steering linkage was in the way, and only other issue im seeing is a little material may have to be removed from the left side support bracket then later add a stiffener. I pulled some wrong foot forwards in the garage and tipped her up a little with about 3/4 tank of fuel in it as well and it seemed very balanced and still light/rigid from what I can tell :face-icon-small-hap

What belt will you be using?

snopromod · Mar 14, 2013

Depends on final location, have to measure it when that time comes..

Climbmax · Mar 14, 2013

Cool dude. How are you going to exhaust it with the Pro Tank and seat? Dump it in the tunnel and a small silencer?
Cheers
RS

snopromod · Mar 14, 2013

Yep straight tunnel dump with 10-12" pipes. Have done this on a few light modded nytros it works great!

For the new viper the rear mount is welded to the heat exchanger and looks really clean way to get the rear mounts in

Is there anyone that could get me pics of that rear mount on viper? I was thinking about doing something like that but didnt know if it would hold up..

couch · Mar 15, 2013

please post lots of pics!

snopromod · Mar 15, 2013

The guys at Adrenalin Junkies will get started on motor mounts in 2 weeks, right after Jackson Hole hillclimbs, I had to take 1.5 inches off steering post then we will later redo steering geometry to make it work, Ive taken alot of time to think this thing through now its just a matter of time to measure fab up some motor mounts and torque link arms on CNC machine. Fuel rail will clear along with air horns below the overstructure, looks like the yamaha belt from nytro will be our best fit since this motor lays down and back more then the polaris motor does. I will post more pics tonight of everything laying in the correct location. Really have not come across a major issue yet, but we will know more once we have bulkhead and tunnel up on bench and the professionals get to work on this thing!

If you search some of the viper threads you can see it. When I saw in person I thought ... Dang that was clever.

snopromod · Mar 15, 2013

Some better pics, you will notice a couple of tight areas but the motor will move back about a 1/4" which will allow a little more room for fuel rail which clears by about a 1/4 already, and will move counter balancer bottom case away from bulckhead. Had to relocate brake caliper, rolled it back about 4", also had to cut about 1.5" off the bottom of vertical steering post so we will have redo steering geo.
