Bike man just announced they are almost tune with the custom tune on the ranger 900's!!! Well it's in their Facebook page anyways lol
We run 2 magnets on our weights which seems to be perfect. If your going up in elevation, you'll want to remove both those magnets. Otherwise, you'd just be down a few hundred RPM's.How many magnet weights would y'all suggest me adding? My normal elevation ranges from 800-1500'. And how many for when I go to Colorado? Elevation from 9000-13000'?
Yes our stage 1 clutch kit that comes with the power and speed is only primary. It is working better than I expected with the stock secondary clutch, but upgrading to the stage 2 clutch kit is the best way to go. You get a much better Tied secondary clutch and a helix tuned just for these upgrades. Back shift on and off the throttle is also huge with the stage 2.Keep in mind that lightening weight without spring changes can result in belt slippage. You really need to do it right with a clutch kit.

Awesome news!Clutching done. 8200 RPM's and 65mph in my crew
Our weights are 59 gram base. With two magnets you're running 61.4 grams which is exactly what I'm running also.It's night and day difference. The 2014 RZR 4 800 I raced when my crew was factory beat me by 5+ lengths and was still pulling from me. Now after clutching and the tune install, I have made up the difference and then some.
The weight I believe is 59.8 grams. I think the arms were 57 grams alone. Maybe Bikeman will validate this for us. I added two 1.4gram weights to each arm. My crew now turns 8200 RPM's. And it's a steady 65mph.
Below is the race after clutching.
Our rev limit is 8500rpm with the tune. Stock ranger rev limit is 6900-7000? My Ranger never even came close to hitting it from the factory.What's the stock rev limit? Is there a speed limiter? After bikeman tune, what's the rev limit? Is ideal shift out 8,200rpm like you're experiencing? As you lighten weight in primary, you'd normally soften the primary spring otherwise your engagement rpm and top shift out rpm would be too high.
Back when I worked in the UTV magazine industry('07-'11) Bikeman participated in quite a few of our project vehicles, exhaust shootouts, etc. In fact, they won the exhaust shoot out on the RZR 800's with the highest overall gain across the broadest rpm range. One of our first ranger builds we had nitrous, clutching, full motor mods on a ranger and it was super fast. They really
know their stuff...now they just need to get the turf mode to work with their ecu.

Exhaust really does work well as that muffler is quiet, but restrictive. Ours isn't overly loud, but definitely louder than stock, especially with higher RPM's.Most definitely. My results have me really thinking about adding the exhaust too.
You should be able to use some components. Obviously the weights need to be changed for sure. If you take your secondary clutch off and let me know if any markings are on the helix that would help. I could tell you how well your secondary setup would work. They just use Team components, so it should have the angle and part number right on the helix.Could I just change the spring and weights in me ddp clutch I already have installed? Also, lets be realistic... I know this setup hasn't been out long enough for alot of feedback, but is there any downsides to this, such as reduced engine life ?
The ECU will still pull things back if something major is going wrong. For small codes you can just check periodically, but these would be situations that would not cause any running issues.So if the check engine light is always on , how would you know when something failed that would normally throw a code?
The tuning is 100% great, not half of anything! Turf mode does not work, but customers wanted the tuning anyways. We have been hounded by ranger owners for 2 years now to get this tuning done. As much as we would like to have everything perfect for release, people did not want to wait any longer.Yea seems to me that they jumped the gun on this by releasing it before getting the bugs worked out... Kinda like when I dropped an old Chevy 350 4 bolt main in my 2001 jeep wrangler when I was 16... I wanted to be the first around to have it... The outcome : it was fast as hell, but only half of what it should have / could have been. That was 15 years ago, I've learned from stuff like this, I'm leaning more towards keeping my 900 how it is
Your cummins does not have nearly the torque limiters of these RZR's. It's very easy to adjust injector timing, fuel map, and boost map... ect on most diesels. We of course adjust fuel and timing, but the other values of custom programming are a huge amount of work.I agree, I want the extra power and I know it's there just waiting to be tapped into, but I want it to stay reliable. I think for 700.00$ it should have all the bells and whistles, like turf mode. Heck a programmer for my Cummins is only 600.00$. I know power cost money, but these things are expensive from the get go and to charge that much it should be tried and tested..
Exactly. We still want it to have turf mode and are trying to come up with a solution.The problem is that Bikeman says this may be the best you get. They don't know when IF EVER they will have turf mode figured out. Its a code thing that they don't have the key to. They said this up front. People wanted it like it is and they provided it.
It's night and day difference. The 2014 RZR 4 800 I raced when my crew was factory beat me by 5+ lengths and was still pulling from me. Now after clutching and the tune install, I have made up the difference and then some.So what weight did it end up being? Around 55? Is it quick? Night and day difference? Worth the $ spent. Any buddies have one to run against?
See edits added in redWhat's the stock rev limit? 6250 Is there a speed limiter? Mine only hit 53 factory After bikeman tune, what's the rev limit? Mine is 8200 after adding the correct weights in the arms Is ideal shift out 8,200rpm like you're experiencing? As you lighten weight in primary, you'd normally soften the primary spring otherwise your engagement rpm and top shift out rpm would be too high. That's exactly what the kit comes with
