Admin needs to make RANGERDALEXP a 5 star Great info Dale. Glad your RZR is fixed grtrnd1! 8)

grtrnd1 · 2009-06-28 14:22:05

I'm new to the forum so I dont know how the Star rating works, But in my opinion he is a definate 5 star. He worked with me everyday and night on this thing. Had to explain things to me several times. He explained it in very definative detail. It's hard to write on the computer and explain things step by step, but with the way he done it,,, It was like he was here. I am grateful that he took the time to take me through it several times step by step. I just came in from running fence line and checking on animals and I'll tell ya,, she runs like a champ. I'm hoping the rest of my time here on the forum is to try to help others out and to ask about the best upgrades. I have 26 inch Terra Cross tires and 14 inch ITP wheels. They rub in the front when turning. I'm a big guy, and would like to lift it a couple inches. What is a descent lift kit for this bike. I don't ramp it or nothing like that. I just work it on the farm, and the occasional trip through the hollow. Some mud,,,, nothing up over the seat or nothing like that. I am just wanting to get rid of the tire rubbing. The shocks are set up where they can only be tightened one more notch. The front end seems like has a down hill rake to it. I haven't looked at any other ones to see if they all look like that. Thanks again Dale, you've been a great help.

Thank you Badley,, I'm very, very happy. I've had it for a little while and I didn't think it ran like it should. I used to own a Honda 450 foreman, and when I got this 800 I was dissapointed in the way it ran...BUT,,,, not now,, wow what a difference. Like I said,, I'm a big fella and it will scare me when you get into the throttle.

Grtrnd1, I am glade it is now working for you, As for your tire rubbing issue you can try something i am not all that found of only because it will add a little more stress to the Axles and bearings but you can use a set of wheel spacers, A lot of people that have rhinos and rzr's use them to give a wider tract and better wheel clearance. They will also add a little more stability and will maintain the front end alignment, they are cheap compared to the proper way of correcting the problem which is a full a-arm kit and axles. those kits go for around $500 to $1000 per axle depending on manufafacure. Wheel spacers are between $25 to $40 per wheel.

LOL,,, Just when I thought I was done. My wife took the RZR out on the ridge today, and there is a long uphill grade on our ridge about a quarter mile long. Darn near every time we try to go up this grade the bike will just loose power and start missing, you have to let off and keep working the throttle to get to the top and it will level out and run fine. It doesn't quit, like it's out of gas, just misses. It ran fine around here today. But when she went out on the dirt road to see the neighbor it acted up on the same hill that it acted up on me before. I'm going to check the TPS voltage again. Any ideas where to look. It only seems to do this problem going up a long grade out on the ridge at about 30 MPH. :?

grtrnd1 · 2009-06-28 19:20:09

I took the bike out here on a night run. I went back to the exact grade that my wife said it missed on... While pulling the grade at 30 or 35 MPH, i noticed the headlights flickered just enough to notice it and it started missing. I stopped and revved it up a couple times and it backfired. I waited a little bit and took off it ran fine. I turned around and started back,, ran good, I was getting on it pretty hard when I noticed the headlights dimmed again and it started missing and backfired when you let off. I realized every time the fan comes on it starts acting up. While the fan isn't running it runs fine, as soon as it kicks on and starts drawing amperage it acts up. Now where do I go... :? I know you are going to hate me after this.... lol

RANGERDALEXP · 2009-06-28 23:06:12

This is really good news to a point because now we know when it happens :idea: , I wished i new this info at the beginning . Now that i know about fact that the extra amp load of the fan when it comes on is when the problem start and stops and this is a big help. I need you to test the voltage at the battery with the engine off and no load at all. then turn the key to the accessory position and give me the voltage, then start the engine and let it sit running for a few minutes and give me the voltage, at this time let it get hot and when the fan comes on give me the voltage again. A fully charged battery should read 12.74 volts and when the engine is running it should be around 13.8 and 14.8 volts. when the fan comes on if it falls lower then 12.0 there is a problem. I like to see no less then 12.5 under any load, below is the order of what it could be.

1. A defective battery because under heavy electrical load the 500 watt stator can not keep up with the load and it will need to rely on a good battery under heavier load periods. The ignition and ecu will need to have the minimum running voltage to run it properly and a bad battery will cause it to not have the proper minimum voltage and it will start it to crap out. Remember the stator only gives full rated output at max RPM. At this point i think it is a weak and defective battery in my opinion.

2. You may have a bad stator and need to check all wiring and may need replacement.

3. The fan may be drawing to many amps and check all wiring and grounds and may need a new fan motor.

4. And i hope this is not it but a bad ECM that switches and controls all your power. this is not likely and i would go with reason number one for shore.

I would volt and load test the battery and do a full charging on it. if it passes and see what happens next.

grtrnd1 · 2009-06-29 07:58:54

Here's what I got.
1. Sitting all night in the driveway......12.73V
2. Accessory switch on......................12.42V
3. Engine running............................ 14.42V
4. Engine running with fan on.............12.99 to 13.50 jumping around
5. Engine running with everything turned on with fan running 13.50.

I don't know what to do. It acts like an electrical problem. There is a winch on the bike, I even unhooked it from the battery to see if that was the problem. I'm going out after bit to see if it will do it again pulling the grade. Thanks.

grtrnd1 · 2009-06-29 09:07:14

Here's some more information for you to ponder on. I just took the bike and ran it pretty hard back and forth here in front of the house. Just short bursts of throttle go about 100 feet and let off. Done that a good bit, the fan came on, came off several different times while doing this and it ran fine. Now,,,,, I took it out on the township road, where the grade is and cruised at a steady 30MPH. I went probably a mile and I could feel the bike starting to slow and started cutting out. I pushed down on the throttle and let off and pushed down again and it cleared up for a second and it started acting up again, I done that several times while still moving and after I let up on it after about the 3rd or 4th time it ran fine again. Now im wandering if it's not a fuel pressure problem. Seems like if I stay on the farm and run around on the throttle off the throttle, down hill, up hill, never over 20 MPH it runs fine, But as soon as I get out on the ridge to go over to the neighbors farm it seems to start falling on its face in roughly the same place. I even went down an old hay road that has fairly big stone on it, and run fairly fast to see if it might be a loose connection, but it ran fine.

I dont know much about the RZR but the voltage regulator may be worth checking as well. I had one go to hell in my snowmachine and it would run fine for a few miles but then when you asked for lots of power it would act up. A bad regulator can cause your electrical system to go all crazzy after it gets hot or under alot of load.

Just a though :idea: this is something I found about the regulator.

That is a good point and yes they do have a voltage regulator and it also could be the problem. But the only reason that makes me think it is not is because the problem only now happens going up a hill and that tells me it is a fuel pump issue or the pump is loseing its prime. :idea:

RANGERDALEXP · 2009-06-29 11:43:13

Put a fuel pressure gage on the fuel rail and and let me know what the pressure is, It should be 39 psi +/- 3 PSI. Also did you replace the the fuel filter :idea:. While you have the gage on the fuel rail i need you to drive it and watch the gage and look at it when it starts to act up and take note on the pressure at that time. This will tell me if it is the fuel pump cutting out. Also the fuel pick up may have an issue. top off the tank after you do all the test and drive it to see what happens. We will hunt this problem down and destroy it . What has taken days to get too over the computer i would have probably found it in a few hours if i was there :!: .

grtrnd1 · 2009-06-29 14:41:54

I'm thinking it's fuel now too. I have to either configure up something for a fuel pressure gauge or go buy one. I don't have anything handy to use around here. Give me a day or so to come up with something, and i'll let you know. thanks

Any auto parts store will have one for around $50. We have a chain of stores on the west cost that is called harbor freight that sell cheap ones and you could look into something like northern tool and Jegs.com or summitracing.com for good professional but well priced gages. I like Jegs.com because i get most of my orders in two days and never had an issue with them every order since they first opened. At Jeg.com goto search and enter Fuel Injection Tools and it is around $43.
