Has anyone used this kit from MPI? It's supposed to provide clean cold air to the SC. It's only $130 but is is really providing better air flow? I don't have an intercooler so I was hoping this would help until I can afford to do the intercooler.

I'm going to run 8lbs of boost on a supercharged nytro. If I run the STM weights, what base weight should I purchase? 50 gram or 60 gram? i believe they can add up to 32 grams with the inserts and washers. I may increase the boost ot 10 but no higher. I believe the stock weights are 47 grams.

I want to replace the pulleys on the supercharger. I bought the sled with the SC already installed so I don't know how it was installed and I don't have the MPI instructions. Can someone tell me what I need to do to replace the pulleys? At least the top pulley, I may leave the bottom alone...

How much boost can I expect from a 26T/29B pully combo on my Nytro at sea level?

Where can I plug this accessory plug into to get power?

I really like the way the newer sleds brake and would love to get something similar on the older Nytro. Is there an upgrade available for a 2008 Nytro?

I have a supercharged sled with a head shim. How much boost is safe to run on pump fuel? I'm currently running 6lbs with 87 octane and have not experienced any detonation at all. If I were to bump the boost to 10 could I still run safely with 91 octane? If I were to do an ECU reflash as well...

I set my front Fox shocks at 65lbs and notice that the clearance on the sled is still very low compared to other sleds. Is this typical for the Nytro? I rode a Viper and the front end seems like it has so much more clearance. Setting the pressure any higher than 65 and the sled handles like...

I'm thinking about replacing my Curve ski's with a set of CA Pro RZR. I like the Curves but they are awfully wide and loading them onto a trailer with another sled with Curves is a pain in the #*$&@! for those of you who use the CA skis and those of you you have tried both, is one more favorable...

I want to install a set of Wahl bros no slip sprockets on an 08 Nytro. What is the size of the shaft the sprockets get pressed onto? 1"? 1 1/16"? 1 1/8"?

Will the Bergstrom Triple points fit on a set of Curve ski's? The cost of these are pretty high but I have heard good reviews. But are you better off buying a new set of Woodys every year for 3 yrs or the Bergstroms? Cost would be very close.

i just installed a trail tank on my Nytro and everything went well until I tried to put the hood on. It seems like the hood needs to slide forward another 1/2" in order to get the Dzues fastener in the hole. I have pushed the tank as far forward as possible but still it is short. The two...

Can MPI's tunnel cooler be installed on a short track? How does Mountaintech cooler compare to MPI?

Is the gearing between the two sleds the same? I heard that the viper uses much bigger bottom gear than the Nytro does. Why is the bigger gear needed?

Anyone use one those bluetooth enabled helmets? They have BT capability built into the helmet so you can link to your phone or ipod. I was curious if they work well or not. They are not that expensive and it would be nice to listen to music while riding. What about the Scala G9? how much...

It seems like this has been asked before but I can't find a clear answer. I have a mountain kit MPI supercharger that was made for Yamaha Nytro's. The sled came with 28/28 pulleys which gives me around 6/7psi running at low elevation. I want to put a head gasket on and increase the boost so...

How can I "permanently" remove the condensation from the inside of my gauges? I can temporarily remove it by heating it up but it always returns shortly after. It is very frustrating especially since they are very new. I have the gauges mounted next to the speedo on my Nytro.

What is the size of the wheel included in the hyfax saver kit? I lost one of the wheels but still have the mounting bracket. Where can I order just the wheel?

I have an MPI mountain kit supercharger installed on my Nytro with 28/28 pulleys. I was told this will produce about 6-7 psi in low elevation. If I wanted to get another 2-3 psi out of this supercharger what pulley combination can I put on here? Would changing the top to a 27 get the job done?

Are all Nytros as hard to steer as mine? I never really realized how difficult it was to steer this sled until I rode a Viper last weekend. the Viper feels like is has power steering compared to the Nytro. Aside from letting out the limiter strap, which is already all the way out, what else...
