I would disagree with the belt issue. i put over 1000 miles on 1 belt on my old 05 yamaha viper spinning at 10500 rpm. yamaha clutches and belts are 10 times what any other brand is. i have had 3 other vipers and 3 other mountain max's spinning at 9600 with no problems what so ever. just use a shallow helix on the secondary to keep your belt tension and keep your secondary wound tight.

Like I said in my first post, turbo is the only way to go.
Evolution Power Sports has a new flash for the viper.. they have dynoed the sled and came up with 160hp with the mods I mentioned. That's all I know about it.. I'm buying a turbo, so it doesn't really affect me.
I see you mentioning 12lbs loss with light weight battery. what battery would you go with? i was reading somwhere else the stock battery only weighs 9 lbs? i'm not sure. i haven't received mine yet so i don't know i'm just trying to figure out what mods to do with mine.
Thanks,

you clutch it to hit 9700 then settle at about 9200rpm were this motor makes the most hp.
this mod will really help turbo sleds out of the hole & on off the throttle
That is the way it was explained to me. Keeps you from hitting rev limiter out of the hole until it hooks up.

Not even accurate. The EVO flash does the fueling you do not use a PCV with it. Air box mod is free, MBRP can is 270 bucks give or take a few. Flash is $599.00 so you can do this for under 1k. Order this flash with to go with air box mod and can - http://www.evopowersports.com/Yamaha-Viper-Arctic-7000-Reflashes/dp/B015UCV8OE?field_availability=-1&field_browse=5145831011&id=Yamaha+Viper+Arctic+7000+Reflashes&ie=UTF8&refinementHistory=subjectbin&searchNodeID=5145831011&searchPage=1&searchRank=salesrank&searchSize=12
Comes out to right at 160 horsepower. BTW the air box mod used for those tests was one of mine, just like the one you took off the sled you bought.
About the RPM, the new Vector motor in the side by side turns 10,500 RPM right? I am not worried about 9600 - 9700 rpm
The test with the EVO header and can and flash and air box mod was the 171 horsepower dyno graph.
M
What dyno graph are you referring to?
You really don't need to tell me anymore about the air box mod. I understand that. I'm putting a turbo on the sled, I don't need it. I may put it on my wife's XTX though.

Barcode vs zbros or oem front end which way to go
M
Depends on what you're into. The 16 OEM supposedly makes a huge difference. I went with the Zbrozs kit because it maintains the 38 inch stance which will be beneficial to me.
A
Thanks that rules out zbros I would like 36 in stance
Well ours not only is 36" its 5" forward. We've found this to really help the agility of the sled.
M
Zbroz also offer a 36 inch kit along with a 38 inch kit.
Personally I'd go with OEM if I were you, if you hit a rock or damage something.. at least you can just run down to the dealer and grab a new part.
A
Who knows when the oem kit will be ready? I want to have sled ready when snow flies. Sun valley got 16 inches yesterday. Starting to lean towards barcode anyplace in boise that can shorten shocks
P
Not sure about moving the arms 5" forward , did the forward fronted on a well set up Nytro and it was not nearly as good as other front ends we tried. Turned into a straight line sled.
I would want to ride one before spending the $$

A couple of the Arctic Cat guys claim that the narrow running boards (Polaris boards or BM Manufacturing) + The "Kmod" steering mod makes this chassis handle a lot better in the trees, even better than the Polaris Pro. The same guy who came up with the steering mod claims the 36 inch stance doesn't address the sidehilling capability of this chassis like the added steering mod and narrow boards does.

Ok anybody else got any saddle time on viper with barcode kit? What's your thoughts? Can't oem until Christmas or something
M
Others have ordered and received the oem kit already.. If you don't mind running white you can just go through arctic cat.
K
No real saddle time yet. But Its crazy easy to pull over, just like their youtube vid shows.
F
Got out for a ride. Just as I expected. Fantastic! Going narrow is good but going forward really makes the sled crazy easy to carve. I was excited when I had it in the garage. Now I cant wait to get out to ride again. Looks like Ill be ordering another kit for the wives sled.
