EVO Upgrade Kit for Factory MPI Vipers are coming soon Evolution Powersports has developed an upgrade kit for the OEM MPI Viper Turbo Kits. Our kit is designed to upgrade the boost from stock levels for the factory kit to 9 lbs (true) of boost at any elevation. The kit includes a set of (3)...

Actually I think a comparison of boost levels is in order to get a real picture. Turbo kit X set at 8 pounds of boost, a 200 to 220hp kit depending more or less. MPI Turbo kit set for 4.5 pounds of boost with EABC, a 180hp kit more or less Turbo kit X is 8 pounds of boost but at higher...

I bought a set of Fox Float RC2 from a member here and sent them out to Gas Shock Repair in Idaho to cut down and adjust for me. Took my Viper out today and ran the stock Fox Floats and then ran back to the truck and switch the stock out for the modded RC2. Wow what a difference! Sled was...

Had it out Thanksgiving but had a few issues including clutching as I chose to ride instead of adjust.....lol. So I took the Dalton QAY 70 and cut the bump off the base of the ramp (like I did the stock 8GL weights before I made the COTC) and cut them down to 68 grams as I ride 10k altitude...

My RC2's are here and going on my sled, those with them can you please post your settings? Save me some setup time ;) Thanks!

I paid full price for my Hygear, just to let you know there is no conflict of interest here. These things are amazing. Putting our stock shock (floats) against the floats with Hygear was a contrast that had to be seen to believed. Now we only ride some low speed trails and boondocking so my...

Finished the EVO turbo install and got to take it out for some real world testing. So you don't get bored too quick let me give the highlights. Testing was at Grand Mesa at 10k altitude with dry powder snow and around 10 degrees to 20 degrees outside temp. 1. Electronics = truly install and...

Video is too large to post here so I have supplied a link.

Just bought a pair of Nytro's that were in pieces that came from a rental company. Friend has little money and wanted to upgrade from his 90 something Polaris so I grabbed these to make one from. The Mountain Nytro came from Yamaha with 8FS (VERY close to 8FP) and a Green/white/green spring...

Girlfriend saw EVOl at the snow show today and wants them for the ride. My question is the Hygear as good as EVOL because it is a lot easier to install Hygear. I am not knowledgeable on EVOL or Hygear add on reservoir help me out please.

How about a thread on cheap or free Viper mods. I will start. EVO thumb screws for Viper hood, take front of sled apart or seat off without a tool. $49.95...

I promised myself I was just going to ride this year and not spend all winter working, but I just can't....lol Ordered EVO turbo kit, should be here soon. Install write up and testing info as it happens. Clutching on the cheap will be updated for turbo's. May not be the same parts as non...

SO if Yamaha is putting what looks like a variant of the Vector engine in the new SXS side by side and it redlines at 10,500 why are we restricted to 9200? ;)

So this year again Dianne and I will be at Grand Mesa Lodge for thanksgiving. ALL are welcome but you should let the lodge know you are coming. Most years thanksgiving weekend is awesome but last year Colorado was hurting on snow and the riding was ok but not epic. This year the state has been...

Hey NOS-PRO and shagman are we going to meet up Thanksgiving weekend again this year for a ride/tune? If we do please note ALL are welcome to join.

I believe I am going to remove my Camoplast X3 x 162 and put on the Powerclaw 162 3.0. I like the Camoplast for deep powder but miss the trail ability of the Powerclaw. Anybody interested in a Camoplast X3?

Because the below happened FAR too often with my 162 inch track Nytro. Now only time I am stuck is when I run out of skill :)
