Stalling problem with my Suzuki king quad 700


Recommended Posts

I bought my Kingquad 700 new in 07 within a few months i had a problem with it where it stalls on me now and then??

On long drives it rarely happens but when i'm playing around or off and on the gas it stalls?? Also this winter when i was plowing snow it stalls too because i was moving foward and backwards.

There are no modifications to it and my filter is clean 3/4's of the time, i run it on super gas, i brought it to my dealer to see what the problem was but on their computer it shows nothing??? My dealer said he phoned the company to see if there was a problem like this before but he will let me know in the coming days!

If anybody would have an idea what causes this i am open for your comments!!!!

Hello FastF3,

I am first time user of this site and decided to sign as I am having the same problem with mine. It's an 05 king. I'm afraid I don't have an answer to the problem and I've also done the service upgrade still no change. I've quizzed an awful lot of service people about the problem but as yet I don't believe anyone has nailed it. Mine has been parked over winter and I haven't worked on it any further but I think I know what I'm going to try first. Mine doesn't code on the computer either.

On the throttle body there is a stepping motor that is told to open and close by the computer to deliver the correct amount of air for the fuel mix. It is very similar to the sytems found on todays vehicles. I have worked on vehicles that were acting much the same and it ended up being a dirty or defective stepping motor. I believe that the stepping motor is functioning but not properly. I will be removing this part in the next month or so to inspect and clean.

There is a great breakdown of all the parts for this bike. The site is called alphasports. The part numbers quoted are actual suzuki numbers. I use it for parts ordering at a local dealer. Saves time and you get the parts you want instead of them telling you which ones you need only to find out they were wrong. Hope this helps. Let me know. If it works for me I'll let know.

Hi, thanks for the message. I found out what the problem was this winter when i took it to my dealer and had it checked and found out that the injector was split?????

Maybe from a bit of water in the gas during the winter periods and froze in the injector??

But without any cost for me my dealer changed it and it works great just like the day I bought it in 07.

Also i changed my air filter to a K&N from a UNI that my dealer gave to me when i purchased the bike and i find it runs alot smoother with the K&N...

Thanks take care!!

I have the same problem with my king quad now. Last september i was riding with my kids and would never get over 45 on the trails, but when i got to a road where i can open it up i cant get over 50 mph. It starts getting terribly hot also. Does anybody have and idea what might be causing that? I checked my filter clean batter is low , but put my daughters batter in it out of her eiger and it still wouldnt get over 50mph. Please help im going nuts:aargh:

Read post #5. To check if this is your problem, you can pull the injector off the top of the throttle body and look at it, also, check the seal while you have it out. Also, make sure all of your electrical connectors are in good shape and plugged in all the way. There is a temp. sensor on your airbox, make sure that is plugged in too. It sounds like you are running lean, so an injector problem is quite likely. I would not ride it again untill you get it fixed. A lean condition can destroy an engine in no time.

      Hi guys. I have a problem where the quad will start and run well for about 5 minutes and then it dies. On inspection the airbox has oil in it (quite a lot). The oil is pumping through the cylinder head breather hose. This problem first happened suddenly. I have since done the top end including, piston, gaskets, rings and valves. I have also done the carb (not that I thought that this was the problem). The compression seems normal. The only thing that I can think of, is that I did not grind the valves well enough. Anyone experienced this? If so, how did you fix it? Any other thoughts?

      Hello, what is the best method for installing bearings into their race? I've set one in place and tapped it down until it was metal on metal. Is that sufficient? Surely it's not supposed to go into the race until flush? Also. does the coil spring on the seal go into carrier bearing housing not facing out? Thanks! 🙂 Seal goes in until flush correct?

      Heres my story. Kinda long. I guess I was a late bloomer when it comes to quads. I had never ridden a quad in my life. Rode Dirt Bikes as a kid growing up. Back in Oct of '06 I found a Mustang on craigslist. Took it for a test drive one morning before work. Fast car. 351 Cleveland. I had planned on meeting the guy again after work. For some strange reason thats still to this day beyond me, I stopped in Hillsboro MotoSports on the way home from work. I had 6 Grand on me. There was a left over '05 sitting by the front door. It was on sale for $4999. It was $5499 OTD. I didnt even look at anything else. I knew nothing about quads accept I thought it really looked coool and I had the money in my pocket to buy it. I was sitting on it when the salesman walked up and asked... "Can I help you?" Without hestitation I pulled 60 Ben Franklins outta my front pocket and said "I want this Quad. Load it up in my truck." It was just about dark by the time I drove away from the shop. BTW, I didnt bother to ask my ol lady if I could buy it. LOL. Anyway, I took it by the house and showed her. She was kinda stunned but not mad. We drove over to a friend of mines house and unloaded it. I took it to the field across the street from his house. HOLY CHIT!!!!! I was surprised by the power. I had it for about 2 weeks and took it to Sand Lake. I was there a few hours and rolled it on a banked turn at the top of the bowl right before you get to the one-ways. When it rolled, I flew off and landed on my belly. The quad came bouncing and landed on my back. For a month I couldnt even walk. I was scared of it. I considered trading it for a 250EX. Went back to the shop. The salesman said..."Dude!!! You dont want a 250EX!!! Trust me. Just get used to it" I still wasnt convinced. I put it on craigslist for $4000. Calls were coming in. I had a guy that wanted to come look at it that evening. I decided to take it for one last ride at Browns Camp before I sold it. I was still afraid of it. After about 5 minutes I started feeling comfortable on it again. I decided right then, I loved my Honda 450 and would learn how to ride it instead of selling it. That was late Nov of '06. Work was slow for a Painter in Oregon. My new job everyday? Going to Browns Camp and ridding my Quad. I bought my Girl Friend an '02 Blaster. I rode my 450 for 4-6 hours almost every single day for 3 months. And yes, I know my way around Browns Camp pretty well. LOL. In March I bought her an '06 TRX250EX (Thank God I didnt trade my 450 for one of those) LOL Since then, I have become totally addicted to quads. I love them. Couldnt imagine not owning at least one quad. Luckily I have two. My "07 was $6500 OTD in July of '07. Bought it for my Girlfriend. Traded in her 250 EX. A month later we broke up. So, I wound up with two Honda 450's.

      So here where I live in Newfoundland Canada, they let you drive your bike on the road provided it’s registered and insured same goes for crossing highways but on trails you don’t need to be insured. And I don’t even think you need a full license to insure your bike they said it was up to the insurance company. I’m trying to get my old 1985 Suzuki 250 registered they have to do a search for it to make sure it hasn’t been in anyone else’s name first. Hopefully it comes back clean I am pretty excited

      I've been using Valvolene 10w 40 ATV oil but, it's like $8.00 a quart. Is that about the going rate? Or is there cheaper alternatives that would be suitable? Thanks
