2003 Suzuki Vinson 500 - Troubles ~ HELP!

Recommended Posts

ok, so I have a decent knowledge of quads and small engines as I worked with them all summer in Oklahoma. However I am stumped on what to do right now. I received a four-wheeler from a buddy who asked if I could clean his carb as he thought the float was stuck. So I did. when I put it back on it worked pretty good. Im pretty sure the starter is bad so I have to pull start it but I did pull start it and it fired up first pull and ran pretty good. however now it will not idle at all soooo im thinking jets? also it dies quickly unless I put my hand over the air intake and "choke" it and it will rev then. ive been readin about a vaccum valve or something? is that the problem? alllso my solenoid clicks and ive light tested it and I believe it is good but starter doesn't even think about working soooo bad starter? I just don't wanna waste a bunch of money buyin stuff and that not being whats wrong with it.

Any suggestions will help me out, thanks so much for your time guys.

i would clean the carb again, take all the jets out and blow it out with air. for the jets, get a twist tie and strip the plastic off to run it thru. there is an air/fuel mix screw too. tighten it all the way in, then let it out 2 1/2 turns. make sure all the vacuum lines are on too. as for the clicking with solenoid, i would take the battery leads and clean them shiny, all the way to the starter for best results. throw a new plug in just for snicks too ...

Alright I will try that this coming week when im free. I will let you know if it works! do you suggest just normal generic carb cleaner spray or what should I use to clean it?

if you want it really clean, berrymans chem dip for a good soak overnight, but you have to take all the rubbers out first, o-rings etc. but you could try the regular spray carb cleaner first and see if that does it ...

And just another random question.. how come somtimes when i pull start it, it will fire up on the first pull and other times it will not start at all?

do you mean pull starting vs. electric start? maybe just luck of the draw, enough fuel, right position of piston stroke. i found out electric start may not go because the pick up coil is set back a hair too far or is dirty.

no my electric start doesn't work because of bad starter I believe. but ya thats probably right... pick up coil? ill have to look into that also..

ok.. so I cleaned the carb again really good. and adjusted what I thought was the idle. it was a flat head top needle right next to the float cover on the carb. I put everything back on and It started up and now it goes on its on at about 4 mph without me pushing gas. also when I ran it before I could get about 40 mph really quickly now I can get 20 mph very slowly. and when I turned it off it back fired like a boss. there is one hose that's not connected on the carb but I thought it was a valve that just is for overflow?

sounds like you might have to do some fine tuning on the carb and adjust the air fuel mixture on it some .. not shure about the hose with out seeing it..sorry..

      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.

      I'm working on my brothers' 2002 Suzuki Vinson 500 . It sat for a few years before I got into it. I'm concentrating on the carb - I replaced orings, needle, etc. and soaked jets, bowl and anything that I could get off the carb that the solution wouldn't eat. I also removed the tank and flushed it with hot water - it's clean. The gas cap innards rusted away and the tank had a lot of rust and water in it before I cleaned it. I replaced the gas cap and installed a new fuel valve because the screens were broken in the old one. The bike will run but spits and sputters and backfires. If you "open it up" it falls on its face and stalls - but starts right up. Here is a link to an exploded view of the carb: Ohio Honda Yamaha Motorcycle ATV Dealer - J & J Motors - Kawasaki Suzuki Scooter Utility vehicle, parts, accessories, apparel
      Can anyone point me in the direction of the problem? It may still be a "clean carb parts issue" . My problem is that the parts list doesn't identify the parts to a degree that I understand. If you said" look at the pilot jet", I'm not sure which jet that would be....See what I mean? It'll run very good if I remove the air filter and cover the opening with my hand and part my fingers a little for the air to get in. Any help is greatly appreciated.
      Thanks in advance, Jim

      got 7 atvs off CL recently for a good price.  one of which is a yamaha warrior.  anyone know where the vin is printed on this bike?  Haha good place to start as I do not know year or size yet.  The former owner says needs exhaust ans and clutch work.  he said it ran fine until the clutch cable broke and then I couldn't get the new cable adjusted right and it would grind gears.  things I see:  clutch cable locked up again, no brakes, carb leaking (green with algae around the bowl and has gelled gas stalagtights on it), aftermarket exhaust melted the airbox so I need something different and a new air box.  I would like the use the current exhaust if I can but I have a feeling its a redneck fix as it looks like there is an ace bandage holding it to the exhaust pipe (its an aftermarket slip-on exhaust), so I'm not sure about that- lets get the bike running first.  also, battery (looks brand new, what a shame) is dead, 0 volts.  Otherwise, bike looks to have not been wrecked, and plastics are ok (it sat outside under a 'tarp' for 3+ years since it was run last).  any tips and advise on where to start first would be awesome as this is my first clutched bike (manual).
      the clutch is my main concern- I've never rode a clutched bike so I dont even know what its supposed to feel like.  lol I'm spoiled on my automatic polaris

      Hey guys, figure you guys would have some helpful direction or answers.
      So, 05 Sportsman 700 carb, new carb, fuel pump, new plugs, new air filter, new everything I can think of that is usually the running issues. Starts up fine, seems to run fine, but if under load, two people, or even one person, up a hill, or pulling a drag chain for the driveway, it starts to cut out and sputters and loses all power, until I back off on the throttle and just barely try to let itself catch itself and then I can take off again.
      I am going crazy trying to figure this thing out. Other than that, the quad runs great. Parents bought bran new, just used around the property, 5000 miles on it. Any ideas???

      I have a 2003 LTZ 400 that i bought a few days ago. The quad was running fine until last night. I let my brother ride it down the street and back and i didnt notice anything etong with bike. Then my neighbors friend came over and said "can i ride it?" I said "sure" so he ripped it down the road all fine and when he got back it died right in front of us. My brother said it was dieing on him also. He also said that he wasnt using the clutch to shift. I told him he was an idiot. Im throwing that in there incase that caused a problem as well. But today i go to check it to make sure its getting fuel which it is and replaced the spark plug incase it wasnt getting spark but it is. So i started it and it was having a problem starting then i got started and was reving at idle high. So i took it around the block and it died on me a little bit down, so i try to restart it and it started so i kicked it into 1st and it kinda launched on me and started going with the clutch all the way in. Then it died right after and wasnt running right during that process and was idleing all over the place and just died and now i cant get it started it again. Before it would start without the choke or priming it. It would start real quick now i cant figure if it needs to be rejetted or something else. Air filter looks clean also. But any help would be gratelly appreciated!

      Blows out black smoke when you rev it up how do you adjust the carb?

      Hi, does anyone know where to find the timing marks on the camshaft and how to orient them? I found the line on the crank and lined it up with the arrow on the case, but the only marks I can see on the cam are on the very end where the black plastic cap is. Are these the timing marks and if so how do you line them up?
