I last road my KRX about a week ago, today I fired her up to take a rip in the snow, it runs fine but when I hit the gas nothing! Don't smell any burning rubber or anything like that. It also would not go into 4 wheel drive either. it has 327 km on it. Any thoughts? I will take it to m y shop on Tuesday as it is closed tomorrow. M

There are a couple of posts on rzrfourms that point towards the belt or throttle cable getting disconnected from the throttle body. Doss the gas pedal feel normal when pressed?

Not sure about the 4wd. How can you tell without power? Does the diff lock not light up?

My apologies for not being clear. It has throttle response but no go. it shows it is in4 wheel drive on the dash but wheels are not spinning. it will max out about 5km per hour

I have to admit, I haven't picked up my own KRX yet so I'm kinda shooting in the dark.

You have limited movement, but acting de-tuned...

Seatbelt limiter?

Also a sensor on the parking break. Maybe something logged in the Mechanism not letting it completely disengage.

figured it out, water had made its way into the belt housing and due to our cold weather it had frozen not allowing for the clutch to fully engage. quick fix! happy birthday to me!

Wow, nice discovery! Had you taken it into the shop it would have melted and nobody would have known. ?

Sounds like the safety switch in the seat belt buckle. I've heard stories about it getting "stuck" which limits power dramatically.

Hey Rob! Teryx forum, I remember ya. I have question for ya and others. My suspension is good and broke in now and I have such a plush ride, but, 12" ground clearance at 10psi in tires. Have others had this? What suspension settings did ya do? Also is the dual rate spring adjustable or is it a 1 preload setting for both? I am almost 71" wide now. I need to put it in air some as Im touching things I shouldnt be bottoming out on. Also considering bigger tires? Any thoughts on a 33"-35" tire?

Howdy!

So, first up... you need more air in the tires. I broke a wheel and bent another running 8-10 psi. I run 14 now, no problems.

Shocks... I've softened mine quite a bit over stock. Stock is 12 clicks out of 24 up front; I'm down to either 8 or 10, don't remember. In the rear, it's set to 6 out of 24 (btw, 24 being full stiff, 1 being full soft). I'm at 2 in the rear. Makes a world of difference and I haven't ever bottomed it out. Note that the softer you make the front, the more it will tend to understeer in corners, so play with the settings until you get it to where you have a nice ride and are comfortable with how it handles. I also run in 4wd all the time because it gets too tail-happy in 2wd.

I haven't adjusted the spring preload either, but that's how you get the ride height set. I haven't measured my ground clearance; have been assuming it was around 14" as stated. But my tires are 90% gone so I'm sure I'm down a bit.

My next tire will likely be a 32 or 33". I was going to go to 35's but the weight is just too high. The stock 31" Carnivores are 37 lbs each. I can get the System 3 HCR350 in 32" at 42 lbs each or 35" for 49 lbs each (these are the lightest of the 35's, btw). Pro Armor makes a 33" that is 39 bs but they only make it in the "hard" compound, which is fine for back east, but won't work well for desert riding, so that's out. Maxxis will have their 15" sized tires on their website sometime in April, so I'm waiting to see what a 32" RoxxZilla weighs. Since the 35" for 14" wheels is like 58 lbs, I'm not optimistic the 32" will be worth considering.

BTW a guy on YouTube did a test on his Honda Talon -- tested 0-60 with stock tires (29") then put 32's on it. It went from 9.5 sec to over 15 sec. That's the difference the added weight will do to performance, so I'm gonna stick with the lightest tire I can find that will work for my riding area (Arizona and Utah desert).

Our riding season here is just about over; will be mid 90's probably by mid-May (with daily hundreds by end of May), so I'm trying to hold off buying new tires until Fall. By then there should be more choices. OR, if I found somebody selling some used Carnivores at a fair price, I'd grab them to hold me over.

In my ideal world I'll have three sets of wheels and tires -- stockers would have sand tires, then a set of 35's for rock crawling, and a set of 32's for regular trail riding. But that's $$$ and I'm not made of it. :)

BTW... what the hell, when I clicked POST, I got a f'ing captcha (select images of type ___). That's BS. I'm logged in. If I get that again, I won't be coming back here. Yep getting it trying to post this too. Later.

I waiting for better tire options as well. 33" would be good and I like carnivores. Im running shocks 4 clicks from soft. 10psi is fine, I dont have as many rocks around here as Ari. Air up to 12 and 14 if I run harder terrain or speeds. Preload is my question, anyone mess with it yet? I am going to add some tomorrow.

I added about 1-1/2" of preload and got my clearance back up to 14-1/2". Was down close to 12". Doesn't seem to affect the ride quality at all. Still plenty of spring to work with.

Not sure what you are talking about. I get nothing unusual when I post.

I am getting some popup virus ad thingy on the other forum... So Bob what did ya set the stop ring on the tinder spring at? Did ya just leave it be? That is what I am trying to understand to set up properly. I will do the preload today. Also watch sxs video with em running krx demo model. It was bottoming out way to easily in sand whoops. Got me wondering if their shocks need adjusted as well? I think so, hope they figure that out. But they crashed rzr pro into tree so bigger problems now.... Those things are made from pixie sticks and bubble gum.

I adjusted my crossover rings up an inch on all four corners quite a while back. That allows more travel before the lower, main spring engages, which softens up the ride on rough, rocky trails. I constantly play with the compression adjustment knobs at the top of the shocks. For high speeds, whoops and jumping, they need to be set pretty firm. I'm more of a low speed rock crawler with an occasional higher speed run where I can. Trying to find the happy spot on adjustments that work best for my riding conditions.

I have been running 4 clicks from soft compression. If I need the change I go to 12-14 clicks. But shocks have settled and tires are 10+psi as well.

The limit switch on my seat belt went bad with 22 miles on it. Had to hold the buckle toward the passenger side for the 10 Mile return back on the trail. I had to put a piece of tape on the clip to push in the little button in the latch so it will go until I get it back to the dealer for repair. You can also click the passenger belt into it and it will pull on the button if needed.
