    Opinions needed from experienced nytro gurus. Hit a deer…

    Hit a deer yesterday, doing about 75, I was somehow lucky to walk away unharmed, but the sled didn’t fare as well. It seems the deer some how hit low from left to right and the sled went right, I kept tumbling down the trail and the sled went right and just missed a tree and took a branch off...

    WTB 26 tooth Mpi supercharger pulley. Found steel alternative?

    Hope to spot a MPI 180 kit pulley, 26 tooth. I have found the steel alternative that gates makes, wondering if I can just use one of them instead. https://www.biedlers-belts.com/catalog/product/view/id/233427/s/gates-p26-8mgt-20-sprocket/category/5437/

    Title says it all. It’s a friends sled now but originally mine. Temps around zero F. he said it died like he hit the kill switch and restarted after several tries, he said it cranks and nothing after a few tries it fired up. I witnessed it happen again the next day. We stopped on the trail...

    2010 Nytro Yamaha/MPI 180SC, hanging idle/high rpms when letting off the gas.

    Sled is running fine but started noticing while trail riding that the rpm’s were not coming down fully when letting off the gas in the corners and would take a few seconds at a stop at times for the ide to come down to normal. It was hanging around 2300 rpm’s for a few seconds when stopping and...

    Sidewinder 129 skid in a Nytro? Suggestions?

    Contemplating a complete 129” sidewinder skid and track swap into a Nytro Rtx If I find one…I have a decent revalve stock setup now from Schmidtbros. Does anyone think it a good move and has anyone done it, or just do a star 128 relocate?

    Questions about coolant temps on a recent install of Mpi/Yamaha 180 supercharger.

    What is everyone else seeing on their Mpi 180 s/c kits? Seems it’s the low speed deep snow breaking trail that really spikes the temps. Hit 208 deg and the stock over temp light came on. Light throttle on packed or little snow and temps drop the the mid 180’s, get over 50 mph and the temps drop...

    Nytro MPI/Yamaha Low elevation kit and coolant temp issues.

    What is everyone else seeing for coolant temps. Air temps mid 30’s, I was running in dry soft snow over the weekend and temps were hotter, high 180’s at best to 205 running slower, say, 30 mph in dry soft deep snow. Installed late last season and was 170-180 with scratchers down packed wet snow...

    Mpi supercharger install issue, airbox interferes with radiator.

    Installing a left over Yamaha/MPI 180 kit per instructions, after mounting the airbox, the radiator is 3/4” off, too high at the bolt holes. I had to cut off the bottom of the plastic radiator shroud to get it to fit. I am pretty sure I don’t have the intake boots misaligned either, but will...

    2012 apex monoshock cable delete settings.

    Is turning the adjustment directly at the shock clockwise or right increasing the compression or decreasing it? Also how many clicks from full rebound stiff is there?

    Phazer tunnel protector thickness issues...

    Found out the hard way that studs will hit with a 3/4" tunnel protector when bottoming out at the rear of the tunnel. The guy I bought it from had installed some home made aluminum protectors along with 48 studs with actual stud height of approx. 1.1 inches. After careful measuring, the...

    Help, hand warmers won't adjust.

    first ride of the season and noticed my hand and thumb warmer rocker switches are not behaving. Had to fight and wiggle them around to get them to adjust up or down on the display. Will look at connection corrosion first. Any ideas are appreciated.

    Fyi for apex RTX, rear suspension shock linkage bearings, they are fixable....

    Hope this info helps others with a pro-active CK rear suspension. The '07-'09 RTX has a billet aluminum shock linkage bracket with 2 non greasable needle bearings. Yamaha only sells it as a complete assembly for big $$$. I pressed the failed larger bearing out. The smaller bearing looks...

    Shock opinions, apex rtx fox floats or ohlin's?

    I am looking at trying a set of ohlin's off a 2008 apex LTX GT with the remote resevoir and adjustable compression clicker versus my original fox floats instead of spending money to upgrade and re-valve them to be more progressive. Think I would be better off going to the ohlin's and selling...

    Limiter strap made of 10,000# polyester webbing vs stock?

    My original straps are showing wear at 4500 miles. Thinking of buying 2" wide polyester webbing and double it over since it's .080" thick instead of buying the stock straps. It has 10,000# breaking strength and should not stretch much if at all. Cost is $6.17 for 5 feet of it shipped vs. $44...

    MPI phazer supercharger possible sale or keep it?

    Looking at a 2007 phazer mountain with a Mpi supercharger setup here in Mn. I don't think I want the setup and wondering if there is any interest here on the board in buying it. Has approx. 450 miles on the complete setup. I don't know what to ask for it but will buy the sled and take it off...

    2008 Apex RTX revs at 11,000 rpm at WOT. Normal?

    Just came back from a trip in the UP of MI. Bought the sled last spring and haven't had a chance to open it up until now. 11,000 rpm at WOT at full shift on loose sugary snow. Belt width measures 31.96 mm- so a little wear. 4,200 miles on the sled. Should I replace secondary clutch buttons...

    '08 RTX suspension questions after revalve. Disappointed.

    Guess the title says it all, this is long winded so bear with me... I need some questions answered about how others RTX's suspension is set up. As it sits 1/4 tank of gas if that matters. I've read to run 45-50 psi. in the ski shocks so the a-arms sit level, and mine is darn near on the...

    Apex RTX rear shock mount wear from track, stud question?

    Just got my shocks back from Carver after revalve. I noticed wear on the top of the rear shock from the track hitting it. Somewhat concerning now that I want to stud the track, I assume can't stud the very center of the track if I expect the shock mount to last? Does everyone agree here about...
