    Best weight saving strategy for Nytro?

    Mountain Mod Seat is a nice weight savings, If you are running a turbo get rid of the muffler and do a tunnel dump, Don't do the light weight battery like Mother Trucker says because when it gets cold the battery gets to weak to start the sled.

    Question about 09 XP

    Thanks guys for giving me a few things to check. I called up a buddy of mine that is a former Doo rider and he gave me lots of things to check too. Should have it figured out soon.

    Question about 09 XP

    I'm not that current on the XPs so this may sound like a dumb question. Are they not fuel injected? So if it is I shouldn't have to mess with jetting? (this is where you can all make fun of me now) The last DOO I owned was a 670

    Question about 09 XP

    A buddy of mine picked up an 09 XP at the end of last year so he hasn't had much time on it. Went for a ride this evening. When he lets off the throttle it doesn't come down to idle. The sled actually holds around 5000rpm. It will come down after you have sat for a few minutes. Or if you...

    goggles

    I use a clear lens most of the time. Usually carry a second pair of goggles with a tinted lens just incase it turns into a blue bird day.

    Started the tnytro for the first time

    Sounds like it will rip. Don't be disappointed when some of your 2 stroke buddies stop riding with you. :d I had it happen to me. They get sick of watching a guy blow over the top of a hill in one try while they have taken 3 or 4 runs at it. Hope it works well for you. Have a great season.

    Drive Chain Question- OEM or Aftermarket?

    I have another vote for OEM. My dealer recommended to me to change out my chain at 2500km on the turbos. When I reached 2500km I did as they recommended and I have that chain as an emergency spare still. I am now at 5000km and will be changing the chain again. Preventative maintenance never...

    Apex turbo gurus PLEASE HELP!

    I am running an 07 Apex with the same goodies. I am running a stock motor with the MCX Headshim. So our compression is approx the same. I run 17psi boost with straight 100LL Av Gas. It is about the same as mixing your fuel 50/50. From what I know about the Apex the Rods and Rod Bearings are...

    mcx 270hp kit on nytro experiance?

    With that kit you just need to run Premium Pump Gas up to 12psi. After that run 100LL Av Gas for 13psi and up. You will have no worries. The system is self adjusting when it comes to the fuel delivery.

    Mcx 310 Driveline noise

    I run Timbersled Suspension in my Apex. I put the stock sized upper boagie wheels on mine to stop the track from rubbing on the shock. I knocked a few track clips as well. Seems like their rails need fresh rail tips all the time or they knock off track clips. When was the last time you...

    regulating over boost??

    Yep, Keep it simple. Liquid filled gauge, Boost T. It's all I run. I set the waist gate for 12lbs of boost and then used the Boost T to turn it up from there. Then pay attention and get it set up to your desired boost and leave it alone. That way you will never run less than what your wastegate...
