I have not heard it in person only on videos. I did not know they made a dB killer for it. I will be checking that out as I don’t want it too loud. And since I’m not turboing it, I would think it would handle stock horsepower. Kinger I tried your boost controlled shut off valve exhaust on my...

Since ezryde has closed there shop and shut down there website. I thought I would give my fellow ty4 friends the mounting locations for the nytro in case someone is trying to mount one on a old nytro.

I had yoshimura exhaust kicking around that I had wanted to put on my nytro but never ended up doing it. I always loved the sound of these exhausts so it will be going on the yamalaris. It was about 8” to long so I cut it off and re riveted it back together. Then I had to weld a flange on it to...

Looks pretty stock. Lol. Awesome sled it must be a animal to hang on to.

I bought a header off a boondocker turbo apex and I modified it to fit the nytro to make it a side exit exhaust. I cut the 4th pipe off and capped it, and had to bend the other 2 slightly to fit the spacing of the nytro. Then built my own Nytro header flange and welded it all up. I then...

Here is a pic of the parts motor I’m using for fit up of exhaust and motor mounts. I wish I had a apex motor to put in here I love the sound of them and the power is impressive. But there is not many of them in my area and the price of them is still fairly high.

The apex has a return fuel system with a rising rate regulator at the end of the fuel rail. That regulator is what I am using for my turbo nytro right now. It is weird that the nytro does not have a return system so I am assuming that the pump regulates it.

I worked on my side plates for drive and jack shaft. I had to shim out the clutch side 1/4” to allow for the nytro driveshaft to fit without Machining. I am using the apex chain case cause it bolts on instead of being integral like the nytro.

Anything I can do to help a fellow ty4 Yamaha rider. I have saved thousands over the years in shop repairs from help from this forum. I wish Facebook would rot in hell

The fuel system was a bit more work than I had figured hopefully it works out. After Some research I found out the stock Polaris pump puts out around 60 psi. Way to high for the nytro which puts out 43 psi. So I modified the internals to fit the nytro pump. It’s nice that Polaris use the...

Man I think you should just go to phase 2 now save yourself a lot of time doing things twice. Trust me my nytro had about 4 phases and 10 years later I’m finally finished it, just in time to start my yamalaris. Build it and break in (or break) the winder motor until the apex is done. Does this...

Ya the coil wires are attached to the main harness. If you want I have a damaged harness that I can clip those wires off and send you for just the cost of shipping them.

My sleds are very multi use. They go from a mountain trip, to ditch banging, to a 5 day fishing trip in the deep bush, and idling down the lake with the family. I have hauled some big loads with my nytro over the years and this one will be the same. Here is a pic of one of my loads.

As with all my sleds they must have a hitch and a rack to store all the junk I like to carry. I tried to keep it as light as possible but it needs to be able to pull big loads

Carbon fibre boards now that’s energetic and would be cool. My first airframes on my nytro we’re out of 1” x 1/8 aluminum square tubing with 3/4” x 1/8 cross tubes. I have found That thickness to be way overkill. And have down sized on the thickness on the last 2 I built. These ones weigh...

As with all my sleds this one will get my home built airframe running boards. Also I put a grey Vinyl wrap on tunnel before running boards went on. And my sled is now officially a Yamaha as the snow flap got installed. I might play around with the flap to make it removable at a later date once...

Next I focused on the seat and under seat storage area. You can buy under seat storage bags but as with everything I do, I’m cheap and I like to build my own stuff so I fabricated a storage area with sign shop material (diabond I believe) I still have to rig up some dzus fasteners later once...

Kinger I am waiting Patiently for your new build. I was sad to see you jump on the new iron. I guess it just wasn’t meant to be. Make sure you put your new apex on ty4 as you tube is so full of crap nowadays that you can’t find nothing. And ty deserves it Adding a picture of my tank as...

I am using a trashed motor ( to much boost, not mine ) as the template to make motor mounts. And fit things until I’m ready for the full swap over. The mounts will look like the viper rear mounts that weld on cooler except I’m not welding on the cooler. As I don’t trust my welding.

Time to work on the rear suspension. It has a spring suspension and I am going to upgrade it to the pro shock suspension. For the time being to save some money as I have a shock that will fit I fabricated a lower and upper rear shock mount, it seems like it will work as needed I cycled it thru...
