2004 Suzuki Vinson cutting out after 1/2 hr

Recommended Posts

HeyI am working on a friends 2004 Suzuki 500 vinson. It would not run so I took the carb apart and clenaned passages and jets and soaked carb overnight. Put machine back together and it started right up and ran great for 1/2 hr then it will sputter and stall. Wait a few hrs and the same thing happens. I took the spark plug cap off cut a 1/4 inch off and re installed the cap. It has a new spark plug in the machine. I cleaned a screen in the fuel line also. It seems like the coil heating up and shorting out or not enough fuel getting to the carb although draining the carb there is plenty of fuel. Any ideas and thanks in advance.

It sounds like a bad coil, when this happens, you'll need to determine if it's a fuel or ignition first.

      On Wednesday, September 18, our ATV was stolen from in front of our house after the locks were cut. This was around 2-3:15 AM.
      We realize the likelihood of ever finding the four-wheeler again is slim to none, but we had to try and put the word out there. We have put countless hours in to restoring this Banshee. It was more than just a passion project, it also was our investment for a down payment for our future house. We are devastated and beyond heart-broken. If you see any suspicious postings on Facebook Marketplace, Letgo, Craigslist, etc., or have any other information, please contact us or the Prince William County PD.
      *Update* We received a tip last night that it was possibly posted on Facebook Marketplace around 8AM yesterday morning with only pictures of the front and of the back of the ATV. The description only said: PM for more details. This came up in someone’s FB Marketplace feed that has it set for a 50 mile radius from Hartwood, VA. She also has her feed set to automatically translate everything into Spanish, so It could also possibly be posted in Spanish.
      WHAT WAS STOLEN:
      2004 Yamaha Banshee YFZ 350
      White plastics with bright green and pink graphics/stickers
      STOLEN FROM:
      Prince William County, Triangle, Virginia
      $500 REWARD FOR INFORMATION LEADING TO RECOVERY. BONUS FOR CONVICTION.

      i have a 2004 Yamaha Kodiak 450 and it is losing oil but does not smoke what is it
    • By Dra O
      posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
      -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
      -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
      -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
      -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
      -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
      -I THINK it has a mikuni model x carb - diaphragm is ID 26mm  OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
      -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
      -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

      Hi Everyone,
      I am new to this forum and hope that someone out there can help me, I have an early Suzuki King Quad 300 (280cc) which starts intstantly every time but at about half revs or there abouts it starts spluttering and will not rev any higher, this fault is present whether choke is applied or not, some one suggested that silencer maybe be clogged so removed baffle but no improvement have removed carb and stripped 3 times but still no joy.
      Any ideas would be most welcome.
      Cheers Rob

      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?

      Took my wolvy for her first trail ride past weekend. Got home and cleaned all the mud and dirt off. Went to take a spin around the neighborhood and started having issues.
      When you are about 1/2 to 3/4 throttle the RPMs will sudden spike way up with little difference in power to the machine. Once you shift to the next gear it will increase power/rpm consistently then same thing happens and you get a sudden RPM spike. It also seems to recreate the problem if you are low in the gear and try to punch it...High rpm with no power increase. If you shift gears and gradually increase throttle she will increase power and RPMs consistently but if you shift and are more than 1/2 throttle it will increase power and RPMs fine until you get about 1/2 to 3/4 way through the gear then you get the same RPM spike...
      Hope I am explaining this clearly. My truck did a similar thing once and it turned out to be a whole new tranny...hope this is a different issue. Thanks for your help guys and gals.

      hi - a friend of mine has a 2004 Honda Foreman 450. His machine will move in 4-wheel drive but not when in 2-wheel drive. WHen he uses 4-wheel drive to start moving, he can then turn off 4-wheel and quad keeps moving. Whats wrong?

      I want to upgrade, not sure what size tires will fit and do I need wheel spacers and lift kit?
      What performance mods do I need to do for the larger tires or don't need to ?
      Like the Maxxis Vipr tires.
      Maxxis Vipr front 27x9R-14
      Maxxis Vipr Rear 27x11R-14
      What size wheel will work? offset?
      Stock 25x10-12 Rears and 25x8-12 Fronts
      Stick with 12 inch wheels and get taller tires?
      Thanks,
