2017 Grizzly

Hi new owner here. Looking for advise on waking this machine up. I'm an engineer so not worried about getting into something. I'm thinking the first enhancement will be a tuner by EHS however they don't list a 2017. What do you all suggest as good bang for the buck I.e. Exhaust tip, clutch spring, air filter, air lid, etc.

Welcome from Colorado.
New tires make for a better grizz, but some wait for the new to wear off some.
Many use C.V.T. mods to change the pulley ratio, then a stiffer secondary spring if the belt slips. It worked great on the older machines.
Call Eric to ask when he will offer a tuner for the '17's.

Welcome! Go get 'er dirty first!

Seriously though, I avoid high pressure anywhere around the top half of the machine and use my pressure washer on the bottom half. No issues so far.

Thanks everyone I ordered the EHS lid and Uni air filter kit as this seems to be a major weak point of the Grizzly. Anything else I should consider is much appreciated. I also plan to block off the AIS.

Since you asked twice;
The low end pull can be greatly improved with C.V.T. mods that raise the pulley ration. This multiplies the engine torque (snap) produced just as using a lower gear in a truck is needed to pull heavy loads.
I got with COOP45 (Arnie) and ended up with him machining the movable primary sheave.
I use shim in combination with the machining to achieve the highest pulley ratio, without rubbing a hole in the C.V.T. cover, which produces best pull with the stock engine configuration.
The shim mod produces a linear effect which reduces the grizz top speed slightly so I cut the cam plate to counteract the shim after the grizz reaches @25 m.p.h., and this put the top speed back where it was. Arnie perfected the shim mod and does this work too.
Much of what I did was to match my grizz to the riding conditions in my area. For the best low speed crawling performance in the rocks using high gear, the machining and shim made the grizz user friendly with throttle control, then in more open areas between towns, once higher speed is reached the cam plate allows for higher speeds without stopping to shift gears.
To complete my combination, I installed heavier weight primary weights to regulate the up-shift for smooth cruising at lower engine r.p.m., and this increased the m.p.g.
Along the way I installed a heavier secondary spring to prevent belt slip from the high pulley ratio, and the heavier spring also produced more back-shift for improved engine deceleration. In the mountains, using less brake input is good.
Your area conditions may cause you to install some but not all of the above mentioned options.
The Yamaha C.V.T. system is very adjustable, I suggest you go slow and add mods one at a time to understand how each mod changes the overall system.

I would think Eric's website just doesn't list the 2017. It's going to be the same as the 2016.

I think the best bang for the buck and with no internal modifications is with the big 3 kit, which he says he has dynoed and increases power 25%. While most big 3 kits include the airbox mod, the one listed on his site doesn't include it, as likely this kit was made before he made the airbox mods. A tip will mostly just be louder. The barkers duals with the spark arresters will give it a nice note, but even be a bit quieter than stock.

I would think you would want to start there, as even if you get to internals, you are still going to want to have it free flowing. Get the Barkers duals, fuel controller, airbox uni filter converter and airbox lid from him for a complete setup. I'm sure he'll cut you a deal on the whole setup, just like he does for the rest of his big 3 kits. Then do CVT mods. See if that's enough.

The 25% will be at W.O.T.
Let us know how the low end performance works out.

I'm new to this, so I certainly don't have the experience, nor first hand knowledge, but from the torque curves and hp curves documented on you tube, there seems to be a steady increase across the entire powerband.

I guess it's all up to the OP, and what he means by waking it up. I agree tires and CVT mods to dial the bike in will allow you to tune it in to terrain and riding style, which may make enough of a difference for him, and is a good first step. It seems like those that went the big 3 route claim that it's really a whole different beast, though I haven't heard any complaints about the low end?

It's all a matter of how much you need and how much you want to spend. Reliability shouldn't suffer with either set of mods, other than additional speed can cause additional carnage, but otherwise all these mods should just optimize what's already there.

Good luck with the build!

Ridgway, I'm closely following your build, as I likely will be riding in the same spots as you, and you definitely seem to have it dialed in for here. I'll have to update those mods to make sense with a 708 that is already geared for factory 26" tires, but your end result throughout the range is what I will be shooting for. It's nice to have a starting point. Looking forward to riding together.

Before you get started, and as I have an older model, I suggest you determine what you have with the stock set-up. This will be important latter when you start making changes.
Start with the tires, and measure the true diameter. I do this by measuring the distance the rear tire rolls over one revolution. I call this the roll-out, which is the circumference, and put that number into the radius calculator;
Circle And Sphere Calculator
I went from 25" stock tires that actually measured less than stated, to 26" tires that measured 26.5"s true.
As a percentage, the actual difference was much more than calculated from the stated tire sizes, and this became important to understand what C.V.T. mods to do.
Then I learned my stock pulley ratio was 2.5:1, so when I added 11% taller tires I knew to increase the ratio by the same percentage to get the stock feel back. Then I went beyond that to 3.5:1. I learned to work the engine closer to the point where the torque and h.p. curves cross, most of the time.
These mods are very important the higher you ride as its the torque that is more important than the horse power, and torque can be multiplied while h.p. cannot.
Also when riding in Moab, the denser air benefit is also magnified.
Another great benefit from raising the pulley ratio is the wet clutch lives longer with hard take-off demands.
I'm sure we'll see each other on the trail.

Sorry to thread jack OP, but Ridgway, do you do most of the work yourself, or use a local shop too?

Ridgway does his own work and he changes ratio's on his 660 like most people change underwear. His 660 is a beast out of the hole, not to mention the "Boy can Ride". He's one of the few that I know of that can ride the "Wall" at Poughkeepsie Gulch and make it look easy. I've had the "Ridgway Experience" on numerous occasions, made me wonder a couple of times about his sanity, lol. He's a CVT Guru with the Grizzly's, he'll teach you a lot.
