I ride an 08 Yamaha Nytro MTX 40th anniversary edition..and I'll see if I can break this down into my love/hates
Love:
Handling in the powder. It takes very little weight transfer to carve..and makes counter steering oh-so-much-fun.
Tall seat
Tall bars
Electric start
Reverse
12v plug
easy to move around on
wide running boards
Torque of the 4 stroke...no need to pin it to get most places you are going, there is plenty down low.
Maintenance is non-existant. Change the oil and ride it. First valve check isn't until what...25 or 30,000 miles?
Hates:
Feels a little tippy on hardpack until you get used to it
The track isn't near as good as what comes stock on other mountain sleds
the rear suspension bottoms WAY too easily
stock skid likes to trench
Front shocks aren't very adjustable
Skis can be hard to turn in hardpack
clutching could use some work (I've read about it on here..mine has been spot on)
The hand warmers work great on nice days. when it gets cold you can't tell they are even on.
Its heavy when you get stuck(other than that you never feel like you are on one of the fattest sleds out there)
vents in the plastic let in too much powder, which melts and is absorbed by all the foam, which then freezes again weighing down the sled even more.
slushy snow build up on the tunnel under the exaust
sticky reverse lever (after a full season on it)
What I've done to make the sled perform better:
tighten limiter straps ALL the way
adjust weight transfer rods all the way up to the red line
install gold finger lefty
increase rear spring to stiffest setting (stiffer springs are available)
hot glue mesh into the vents to keep snow out
remove all the under hood foam
Whats in the future for my sled? Simmons Gen II's, Timber sled rear skid, Powder Claw track or 2.25 camo extreme, better boards, and down the line a NW turbo running 6-10 lbs...nothing too crazy.
Overall I really like how my sled rides. I can hang with most 700's that I ride with, and thats good enough for me.
I hope that helps!
