Time to start making the Summer Mod List for my Yamaha Nytro SE.
- Thread starter christopher
- Start date
So the stock sled came with a "Single-ply Camoplast Maverick, in.15 in X 162 in X 2.25 in"
And you are saying the BEST would be 1 inch wider and only 1/4 inch deeper lugs??
Stay with your stock track, the 2010 version works well, not as good as the 2.4 CE but way better than previous versions. The 16 wide on the Nytro affects the handling big time.
I did the excell full exhaust and it made a huge difference. I needed a lot of weight to get the RPM's back to stock.
Do the full exhaust and clutching and you will have a fun sled.

Yes that AND the muffle they offer would = the full excell system...the header I like but I personally would get a different muffler.
While the "new" Maverick might be a little better than the old one, it is still a Maverick. The pattern of the lugs on the track just likes to trench. I put a 162 x 15 x 2.5 CE Extreme on my 2010 after 99 miles of the Maverick. Spendy upgrade on a 12k sled, but really, I mean really made a huge difference.
Clutching on an N/A Nytro in the back country is a huge deal. What you want is a lower RPM engagement, a smoother upshift and a good backshift. You'd be amazed at the difference that it makes. Yamaha, in my opinion, had their head up their you know what when they clutched the Nytro MTX's. Too long to engage, too hard when it does, not very good backshift. All of this leads to the sled feeling even more underpowered than it is and extra pulling on the ski loops.
Add an instrument panel vent to your list as well. You wouldn't believe the heat that comes off the top of that motor
And to anyone else reading this, take an avalanche class this summer. The conditions out there this year across a broad section of the Rockies were more than ripe for catatrophe. Learn it, live it, save your life for another day.

Chris i would almost be willing to bet you that if you changed your stock track to a Camo Extreme 15x153 or 162 with 2.5" lug and you didnt feel it made a huge difference id buy the track from you for full price. As far as other mods it really depends on what your planning on down the road. And it all depends on your price range on what to get first. If boost is an option i wouldnt worry about a header. My mods if i were you would be in this order. TRACK - 700ish, Nitrous - 800, OFT Relocator, MtnVipers rollover kit, SKIs, Undertunnel exhaust (shaves alot of weight), lightweight battery
That one was easy.Add an instrument panel vent to your list as well. You wouldn't believe the heat that comes off the top of that motor
Done.
I am pretty well set on an under the tunnel exhaust system.
I REALLY want that space open under the seat and on top of the rear tunnel for emergency gear.
Care to share what your setup is or what you are using?
I second that.
I would be interested to know as well.
One of our members sent me this list to look over....

I am sending this to you in response to your question about upgrades.
Changing out the exhaust is a pretty good way to shave some weight and add some additional horsepower.
Here's a list of products:
Skinz SuperQ Exhaust (+ 3-4hp) = -7.5 lbs @ $249.00 = $33.20 per pound
Skinz UltraQ Exhaust (+ 3-4hp) = -7.5 lbs @ $289.00 = $38.53 per pound
Ulmer Racing Exhaust + Header (+ 8hp) = -8 lbs @ $850 = $106.00 per pound
Hartman Exhaust (+ 3-4hp) = -7.5 lbs @ $255.00 = $34.00 per pound
Schmidt Bros. Exhaust (4-6hp increase) = -7 lbs @ $699 = $100.00 per pound
CR Racing Dump Kit exhaust = -7 lbs @ $300 = $42.86 per pound
MPI Exhaust = -11 lbs @ $319 = $29.00 per pound
MBRP Exhaust = -10 lbs (+2hp) @$250 = $25.00 per pound
Aaen Mega Power Silencer = -7 lbs (+6hp) @ $425 = $60.71 per pound
Excell Motorsports Exhaust = -8 lbs @ $849 = $106.12 per pound
Ulmer also sells a header that won't save any weight but adds another 6 hp. Their exhaust + header adds a combined 14 hp. The header costs $500.
I have the SuperQ exhaust and like it. The UltraQ sounds like stock, the SuperQ is deeper and a bit louder.
Changing out the battery makes a lot of sense too. The stock unit is a beast:
Yuasa YTZ10S battery = -10 lbs @ $135 = 13.50 per pound
Yuasa YTZ7S battery = -12 lbs @ $135 = $11.25 per pound
The 7S has less crank power so it may not be best if you are often in cold conditions.
Hope this helps.
Joe

It's the standard three weight set up
Has a couple of springs, some rollers and a helix too. Email me at scott@OFTRacing.com if you need any more information than that.

For the batteries i use the 10series instead of the 7 still alot lighter then stock but still enough for those cold days.
I have to wonder if I would get more bang for my buck taking 25lbs off ME or off the SLED!!
Boy ain't that the truth though!
