    Split Rail Ski Help

    I had tried that originally, but it still looks like there in enough room for one more washer. I will put the washers on top and bottom then tightened it up. Maybe that will draw it down? If not I'll add one more washer, just wanted to be sure I wasn't missing something. Thanks for the help!

    Split Rail Ski Help

    Hi All, I picked up a set of split rails skis used, the end of the season last year. I just got the spindles and a-arms back from powder coating. While attempting to mount the spindles up with the provide hardware, I noticed a big gap between the spindle and the ball joint bushings. The skis...

    Intake boots

    Hey Pete, If you get a K&N filter kit from Ulmer he recommends you remove the round spacers from the intake boot clamps. I overlooked this the first time around and the intake boots would slide right off the throttle bodies. I would ditch those spacers when you go to put it back together. That...

    Bogging and Shutting Off

    Sounds like sled could be having a lean condition. I would look at that fuel controller and all the wiring/harness around it. Check plugs for color. I would remove the fuel controller from the sled and test it. You wouldn't want to leave it without one for too long, but that might an issue...

    2014 Cat XF 1100 Turbo... Wow that was boring.

    Can't beat the Yamaha 4 strokes for reliability and ease of ownership. I put just over 1000 miles on mine so far this season and have done nothing but turn the key and go. I did have to replace the rear outside idler wheel after hitting a stump in a snow bank, whoops. Nytro40th, How does your...

    2014 Cat XF 1100 Turbo... Wow that was boring.

    Yeah, I love the way the nytro pulls. It doesn't bother me that it doesn't have the fastest top speed, cause I race it on a lake maybe twice a season. The rest of the time I'm on the trails where it has no problem keeping up. What's a good clutch setup for best corner to corner with out losing...

    2014 Cat XF 1100 Turbo... Wow that was boring.

    Me and some guys at work skipped to ride yesterday. We lined up a '14 AC XF 1100 turbo, '06 Apex, '01 XC 700, '03 edge 600, '04 GSX 600 (all stock) and my '11 Nytro RTX (PC-5, K&N, and D&D can, stock clutch) on a reservoir with 1-2 feet on hard pack on it. The stretch was about a mile. We ran...

    Full exhaust PCV setup....R U seeing better top end speed

    I have PC-V, Ulmer K&N kit (his fuel map) a D&D can, stock clutching and 170 double backer studs. the best top end I have seen on speedo was 101mph, but the GPS in my pocket said 95mph. I maybe gained 1-3mph on top end, but I did notice an increase in pull when accelerating. I would have to say...

    42" Skinz Front End worth it for RTX trail sled?

    Thanks for the info everyone. I was googling split rail + nytro right after I posted this and I found a set of split rails used, with carbines in good condition for $400. I hit commit to buy before I knew what happened. I have read good things about them and the price seemed right. I hope I...

    42" Skinz Front End worth it for RTX trail sled?

    Hey Guys, I am thinking hard about buying the Skinz 42" front end for my '11 RTX. I live in upstate NY and ride all trails (most groomed, some not) and ditches. I was hoping to get everyone's opinion about it on before spending that much cash. The Warden (wife) put the squash on a new Viper...
