Holy moly!! They are expensive! Thank You for the links man, I appreciate it.

I have a 2002 Quadrunner LTF-500F and there is no Front diff switch or low-Reverse limiter on these machines. Sounds like a bad supressor cap or maybe a carb problem. You may be mistaking a "rev-limiter" for a common misfire. These quads don't have rev limiters built into the CDI box.

54 and sunny for GOBBLE day.

Here's mine.

I have a Moose plow on mine, I was just wondering if that was one of those" flip down" when yah back up type of set-ups.

What style plow is that?

@ marioweldinginc......That's how I used to fix check engine lights on my winter beaters.

Great....That confirms it and I can cancel the visit to the nuthouse!! :-)

Is it just me? When I browse Quad crazy there is a dot that shows up in the top center of the screen. What's up with that? It doesn't matter if I'm on my PC or laptop. I dunno if I'm going nuts and just seeing things, but I swear it only happens on this site. Little white dot centered on the top. I thought I had a dead pixel on my laptop but it only shows up here. anybody else notice it??

2002 Ltf500f.....I'm looking for the soft plastics for the rear fenders. They wrap the rear fenders and run down to the foot pegs. Mine are cracked in the "heel" area. I have them zip tied right now but a new set would be nice before we move. If anyone has a set I'd be interested. Thanks.

Make sure it's not stolen.

Still running great and this thing pushes topsoil and gravel better than some small tractors. 50" blade and It pushes with no problem. Gotta use lo if it's really wet. ITP Mudlite radials and mud = FUN!!!!

The choke on mine was the biggest problem.

Thanks again Josh. This thing runs so good I just cannot beleive it. I left it idle for over 15 mins and it never skipped a beat. The fan never even kicked on with the the temps in the upper 70's. I'm gonna have some fun with it this summer for sure!!

If it's the same as mine the idle adjustment is on the right side just under bowl. It's a cable style adjuster so it's "remote" so to speak. It should have KNOB look to it. Clockwise increases idle speed, counter decreases

Side note.....I can finally start it with the pull start and it fires every time, first pull. That hasn't ever happened either.

I'll be damned!!! I looked over the cables and hand controls and found the choke cable adjuster was completely off the threads and the locknut was off the tube. It makes more sense now cause the cable was a pain in the butt to put back on the carb. The cable elbow is under the handgrip so I never noticed it had come loose. It explains why it would die when making tight turns as well. Once I put the cable back together and slacked the hell out of it the engine ran GREAT! Idles like a charm and once I re-adjust the choke cable i'm confident it will run like new. I feel like an idiot that such a simple fix caused that big of a problem. I changed the plug and ran it around for a while and I have to say this thing has NEVER run this good since I've owned it. The plug looked good after about 15 minutes of running it. Light brown, not BLACK and carboned up! Thank you all for your help.

Thanks Josh. We are talking about the same idle air screw. With some time away from it and your help I'm gonna look over the entire choke set-up. I checked everything in the carb and it was all clean and open. I just ran it a bit tonite and the choke does NOTHING to change the way it runs. I'm gonna check to make sure the cable and hand control is actually working. This problem was happening before the carb rebuild but I only removed the cable then put it back on when I put the carb back on. I didn't check to see if the cable is pushing the plunger back down. I'll keep yah posted. I think I might have "thought" of the source. Thank you. Someone also mentioned the fuel petcock could be bad sucking fuel into the vaccuum port causing a rich condition but that seems to hold vaccuum just fine.

By pilot screw, do you mean the one for the idle circuit? I have tried to lean it out to Dangerous settings and it still runs rich as heck/ By Dangerous, I mean 3-4 turns open, and down to 1/8 turn closed. It doesn't seem to make any difference. I'm really thinking it is in the choke. I'm puzzled and ready to just buy a new carb......but I'm stubborn. Maybe I'm missing a screw somewhere> I walked away from it and waiting for better weather.

oops, I guess I didn't realise there where 3 pages.

One easy test would be to use compressed air to find the leak. 30 psi is way too low. Drop the piston to BDC and use your compression tester fitting to pressurise the combustion chamber with an air hose. Look for the leak. The rings will blow buy but if it's a valve seat issue you will hear it thru the carb or exhaust. If the jug or head is cracked the cooling system will start to bubble out coolant. ( remove the oil filler cap and radiator cap before doing this) If it's air cooled, forget the radiator portion.

Ok, I see idle issues here but none of them seem to fit my problem. My quad idles High when cold then is stalling when warm. ( High enough that I can't get it into gear.) Carb has been rebuilt, air filter is clean, Compression is good,it's fouling plugs like crazy and the choke seems to make very little difference. I've checked all the cables to the carb and it just doesn't make sense! It acts like a choke problem but everything checks out ok. I may try changing the supressor cap but damn, I'm getting tired of throwing money @ this thing. If I get it warmed up good it pops pretty bad during deceleration. Could a clogged muffler cause this? I've done everything I can think of on the intake side. Just wondering if anybody has run into issues with this style muffler/spark arrestor. All I can say right now is

My 2002 has a similar problem, It idles fine when it's warmed up but it's a pain in the butt until its warm. Very speratic idle. It will run up too around 2500 rpm then fouls the plug if I leave it to idle out of gear. The choke doesn't seem to make any difference. Other times it acts normal and it runs like a champ. Tells me it's a dirt issue.I'm almost positive its a carb issue. After the snow is melted the carb is certainly coming off and being cleaned! I was going to go as far as pulling the jug and re-ringing it but the compression is very good.( just over 1K miles.) Last compression check showed 180, engine warm. Last plug I changed looked NASTY! Way rich and possibly oil fouling as well. I'll tear it down as far as I need depending on my budget....wich sadly is slim right now. I feel your pain man.

I put a Moose plow on mine and I love it. They are built tough. Cheaper is not always better.

Looks like the outer cage cracked. I cut the boot clamps and slid the boot up the shaft to inspect it. The outer cage is broken into 2 peices. all the balls are still in place, thats definately the source of the noises. I greased the heck out of it and put some old style clamps back onto the boot. Looks like a rebuild is in order. They don't look too hard to do, finding the right parts might be a challenge. Hopefully it makes it until spring. Sorry, I wasn't sure how busy this forum was so I put it in the AG.
