My viper has the mpi 190 kit on it. I bought it with 420 miles 2 seasons ago and before I ever rode it I swapped the track. As I was putting everything back together I checked the chain tension and it seemed fine. I had a Yamaha tech come take a look just to make sure I put everything back...

I installed the MPI EABC on my Viper with the MPI turbo kit. Followed the instructions properly and now when I turn the key before starting there is a chatter under the hood and I get a P0113 error code. I tried turning the key off and on a few times but not change. I eventually decided to...

I did some searching on here but it seems like everyone has the additional pressure chamber whereas I didn't. I set the float to 130 psi where I've read it' supposed to be for the stock setup and the rear end sags so bad the flap almost touches the ground. I was finished working on it for the...

So I buy this sled last season thinking it's going to be the best thing I ever bought. '15 XTX LE with MPI 190 kit. First thing I find out is the turbo was a mountain kit, not a trail kit so no EABC and a very basic analog boost gauge. Come to find out the 190 turbo is capable of making more...

Seems my problems have worsened since my last post. I was a little low on oil and the sled kept cutting power for a split second so I thought it was a sort of limp mode as a result. Topped it off and it did the same. A mile into the ride it lost power as of I hit the kill switch but only for...

Put about 400 miles on since I changed the oil in fall. Everything good for first 300 or so but noticed my oil light on after a fuel stop. Check the oil and it's at the low end of normal range. Start sled no problem rest of the day except it died on takeoff from a warmup shack. Figured maybe...

Hi everyone, I did a search on this and found a lot of info but everyone on here seems to be much lighter than me. I'm 6'3 - 300 lbs and I don't like to slow down for bumps. First 300 or so miles and my 2015 XTX LE is kicking my #*$&@. (A group I ride with uses Polaris RideCommand and my...

Looking for some pics of how to run wiring and hose for boost and AFR gauges. I'll be mounting them in cups on either side of my main gauge pod. I'd like easily accessible disconnects to make it easy to take the hood off. Thanks, Ryan

Just went for my first ride on my XTX with 190 kit. No boost controller so I adjusted waste gate all the way out, still hit 4 lbs on a wide open 10 sec run. Temp was very cold, -25C. Conditions were ungrounded ditches some powder but not much. Cobra 1.6 track, stock gearing. Sled came with a...

Recently changed my track and didn't realize I didn't have to pull the caliper apart. I put it all back together but now it won't pump fluid down the brake line. If I pump it the old stuff will come out the bleed screw when loosened but I can't get it to actually feed in. Whenever I've done...

I've been doing some reading because I know I want to install the ROV with tether on my new sled. I've seen threads on where it should be placed, etc but had some questions. Some people were complaining about oil STILL splashing out with the ROV installed. The oil line looks to go up and...

My recently bought XTX LE has the GYTR front and rear skid plate. The rear portion is really nice but I don't like having to remove it to do an oil change. I was thinking of cutting it into 3 pieces to so I can just take the center off. Had anyone else done this? I was also thinking instead...

After a winter on headaches on a brand yellow etec I came back to Yamaha. Found a really good deal on a 15 XTX LE with only 426 miles and the mpi 190 kit dealer installed. Basically saved $10k off of brand new. The sled came with the MPI muffler but has an Aero 4" muffler on it now. Did a...

When I bought my Nytro I knew I was going to be paying more for parts than other makes and generally I was right. $120 for new upper ball joints, $223 for a new seat mount/exhaust shroud, etc. Pricey but it is what it is. Earlier this month I started getting the sled ready and when I took...

Got a code 81 toward the end of last season and did some research on here, found out the 2010s were famous for them crapping out and throwing this code. Decided to get new bars, risers, heaters and grips. The supplier I get everything from carried SPI heaters, but after getting them I notice...

About a year ago I saw a bracket someone had fabbed and was selling that you mount the K&N filters to so they don't fall off. Does anyone have any info on this? I tried a search but found nothing. Thanks, Ryan

Last year I removed my rear plastics and trimmed my heat shield to give it a "naked exposed exhaust" look. I guess I trimmed it too much or the wrong way and the shroud is bending. I've seen some of you used polaris mounting brackets or made your own and I'm curious as to how it can be done...

So last fall I trimmed my seat mount/heat shroud to run "naked" exhaust (see pic). I've seen other people people do this but my arse is fatter than most so I bent the shroud slightly. I was going to get another one, leave it as is and reinstall the plastics but I'd like to see what other...

First off I want to say the damage was my own stupidity and not a craftsmanship problem by Mountaintech. If anything their excellent product and hardware saved my engine. This is one of those ID10T errors on my part. When I installed the plate I stripped the threads on the 2 front bolts and...

I tipped my sled on it's side on Sunday by accident and thought nothing of it because I had bought the roll-over valve. The sled didn't turn off so turned it off. Tipped it back track-side-down and started it and the oil symbol was on. I let it sit there 10-15 seconds idling and it turned off...
