I need to upgrade and downsize the fleet. I have 2 Apexes, 2 Vectors and 2 Phasers, all with mountain packages. I want to keep my one Apex as its is set up for my riding style. The other 5 are being sold. I need a back up sled for my wife as she hates my Apex, too big and heavy, but I want the...

Hi guys, first time posting on here. Love this site, it’s helped me solve lots of problems! I’m new to the turbo world, it’s a big learning curve. i have 15 viper with the mpi trail kit I was trying to plumb in a boost gauge this weekend when I came across a series of problems 1. My bov was...

Hi guys, I broke the sway bar on the left side just inside where it enters a plastic housing. Can anyone tell me how to remove and replace it? Do I need to remove the skid plate to get at the mounting brackets? Any other hints? Thanks!

Comes and goes, kills my display too. It started happening after I tipped the sled last week. Haven't found any shorts. Checked every connector except the ones below/behind engine that are hard to reach. I don't have heated shield acc. I suspect oil got into the engine connectors... Ideas?

Is anyone else having starter issues with a 2014-2018 Yamaha Viper? Would really appreciate some help or guidance. Please DM me. Thanks.

Has anybody had experience with these tracks? I bought a Talon 32 after reading good reviews on them. I must say it’s a heavy duty looking track. The lugs are very thick and the clips are unbelievably thick! It looks to be high quality, very little rubber flash, no cords hanging out. It has a...

Greetings! One thing I am realizing is, that while snowmobiling in my home state, more often then not I am in loose powder on the Forestry Roads, and most times Very Deep ... Not a bad thing , but I am thinking I may have to change my setup some... This year I went with a Wider Ski, opting...

Hey guys! I've been riding my Viper XTX for about 1,100 miles now and have noticed that every once in a while, my oil light will turn on when I shut the sled off. Do you think it's just the system notifying me of low oil pressure (which obviously happens when you turn an engine off) or is there...

What's the difference between the Nytro PC5 and the Viper PC5. And will either one work on a 14 xf 7000. Been trying to get in touch with Ulmer racing but no luck yet! Thanks.

MCXpress 270 kit installed from shop, got it a year ago. Recently it's been coughing more and more, like I'm feeding it bad fuel. Thinking it's the fuel filter, but I'm not sure. Just did a service on it, changing oil and spark plugs, and nothing improved. It gets better when it's gotten warmer...

Ok, have you tried adjusting the headlight on your SRviper/Sidewinder/Cat ProCross sled? IF you have the correct tools, you can kinda get it close while in the garage, however we all know as soon as you are on the trail, it isn't quite right! Sometimes not even close! The best way to set your...

2015 Viper with mpi 180 kit that I installed last season Just installed a pcv pti from Allen with his mapping. Also 430 cc injectors, a D&D oval muffler and intake pipe is outside for cold air. Allen said I would be at 210 hp with 6 or 6.5 pounds of boost. He told me to set it at 5 or 5.5 for...

I need to replace the track on my wife’s viper xtx 141. It has a cobra track on it now and I really don’t like it. What are people running on there xtxs I notice there’s not many options on the 141s.

I have a 09 Yamaha Nytro XTX and I'm considering selling it to get a Viper most likely a 14 or 15. I don't want to regret it if I do get the Viper. What should I do?
