I'm not a clutch expert but my 12 800s gets to 64 mph at 6250 rpm no clutch kit all stock call the vendor you got your kit from and ask them

 

I did that but I did what I they told mee to do and it did not work.

The change I did was what they, the dealer, recommend for the altitude I am at.

I had a 2009 rzr 800 with what I thought was the same clutch setup. It had a top speed of 58 mph. This newer razor runs great from 0 to 45 and that is where I am at. I have marked the clutch face and ran it to 6200 rpm, the belt goes to the top so I know it is hitting the high gearing ok.

 

Don't understand cause most 800 rzr should do 60 mph of course I'm running a stock clutch with 26" tires and I'm at sea level I get 64 mph at 6250 rpm
What altitude are you at and what size tire ?

 

I am running 27-9-12 tires all the way around. Am at 5000 ft and going to 10000 plus. I maybe have a different problem than ordinary. When I got this razor it was new, but we took the added on engine brake clutch out of my old razor and everything seemed alright. I thought anyway, I have used it mostly for hunting and did not try to go fast. Lately I noticed a power drop in high range. My mechanic thought maybe I needed new weights and pins and so on. We took it apart and really found no problems, put it back together and put a new belt on. Did not fix anything. Got to checking it out and was told to change the was to 23-58 and use a black spring. This is to Change for our altitude. I gained a little power but still only can get 45 mph. It tacked at 6000 max before, now after the new was it tacks 6200 , I think that is why I gained on the low end power but it did nothing for the top end.

 

Also I will add that I had my old, 2009 set up the same way as the new one and it ran like it should with a 58 mph top speed.

How many miles do you have on it would it be a compression problem?

 

Which clutch kit do you have Dalton ??

 

I'm not sure what clutch kit I have. I have 2300 miles on it. Have had a good air filter system since it was new, doubt it's a compression problem.i

 

Low speed and low rpm rarely almost never a clutch issue and always a lack of power problem

Once the belt is fully shifted out the tuning components do nothing

I would stop looking at the clutch and start looking to see what is robbing power

Not saying your clutch tuning is right either but that is not your main issue.

You did say you swapped clutches go into detail on years and models on that

I recommend starting with a compression test. My 2013 800 just hit 2200 miles with 200 hrs. and when I changed plugs I found my compression down to 150 from stock specs. of 165.
I have been anal about keeping filter clean and still dusted the engine.

 

If it is a clutch problem contact Todd at hunter works he has helped many forum members with clutch setup and IMO Hunter works has the best clutch kits and after purchase support

 

Thank you sir!!!

Todd

 

Are you using a GPS to read speed or the speedometer?

 

Yes, a gps and the speedometer so I know it's right. They are about the same.

 

Do a compression test change the plugs while your at it and then a fuel pressure test. You will not figure out your problem but just assuming that you have good compression and fuel pressure

 

I had the fuel pump replaced at 1700 miles. Really don't think my compression is down. This rzr runs awesome from 0 to 45. Tacks to 6200 rpm. Which may not be quite enough. Uses no oil. I just t hi ink I have a clutching problem. Red rock atv says they can get it right but they want about $300.00 to do it. I will probably do that but I wanted some opinions.

If they fix it, report back what the problem was.

 

Several Sportsman riders have reported similiar issues and found out the secondary clutch buttons were shot. Wondering if this could be the same issue in the RZRs? I've got similiar issues with mine.

 

I just had the weights and new bolts were put in but I don't know about buttons. I am having this done, I am not to knowledgeable about it. I will have to ask if the buttons were changed also. This is really bugging me though, I need to get this thing fixed. I appreciate the input from all of you.

 

I had this same issue with my 800 after installing a Team primary clutch. Talked to Todd at Hunter Works (where I bought the clutch and Dalton kit) and he suggested I look elsewhere. Just did a fuel pressure check and had 20 psi at idle. New pump on the way.

 

No doubt. Todd knows his stuff and has helped me with other issues. I thought mine was the fuel pump too. Had 25psi at idle, replaced the pump, now have 42psi...but still got the loss of power above about 40mph. Compression is fine. Only considered the secondary buttons because it seems to be a fix on the Sportsman forums. And I know the buttons in both my primary and secondary have at least 2500-3000 miles on them.

I still want to know what fixes yours.

 

Mine is doing the same. Any resolution?

Hi, I still am not sure I corrected the right problem but I ended up rebuilding the secondary clutch. I have #30 weights in the primary, may be too heavy but now I have a very powerful low end and I can get it to 54 mph on the top end. I am going to try this for a while. I do have engine braking on my razor.

 

I said #30 weights, I meant 70, typed it wrong.

 

high elevation, big tires and extra weight could be a factor.
is your rzr loaded with bumpers,winch, nerf bars, tools, roof and full tank of fuel all that stuff adds up and takes a toll on MPH over 45

 

I am having the exact same problem u are. My 800 won't go over 45mph or 5 800 rpms with my 30 inch tires. I checked compression and I lost a cylinder. Have a new 808cc cylinder works kit on the way
