This is my 1st atv project... I'm use to trucks.

I have replaced both fuel lines and it's not leaking from there anymore. I cleaned out carb and it's not leaking from there. Nowhere round hose's and carb are wet...it looks like it's leaking from bottom of atv... I'm baffled. I hope someone can help

The lines from the vent on the carburetor go down to the bottom of the bike. It sounds like the needle and seat on the carburetor are leaking. This is really bad because it's possible to fill up the engine with fuel. To properly test the needle valve with the carburetor apart put the float on with the needle jet in place in the seat. When you hold the carburetor upright the float will drop down and you can blow through the fuel inlet. when you flip the carburetor upside down the weight of the float will now be pressing down on the needle and seat. You should be able to pull a vacuum on the hose attached to the fuel inlet on the carburetor and pull a vauum with your mouth, seal it off with your tongue and it should hold vacuum.

      New Guy, Busted 2000 Suzuki Quadrunner 500 Project

      Hello all!
      I was given a 2000 Suzuki Quadrunner 500 (Quad 500 Runner?) and its current state is a bit of a mystery!  
      Kept indoors but hasn't been run in 5 years.  We're not trying the engine until the gas is replaced, and the tires are reinflated. But the previous owner said their only issue was stalling when shifting to reverse without giving some throttle.
      I'm optimistic!  See y'all around!

      Leaking valve seals?
      By LCP92
      Guys, I've got a 1999 Honda Foreman 450S.  It runs great, but smokes out the exhaust after startup until it warms up.  I'm thinking the valve seals are leaking.  I was wondering if there is a way to replace them without removing the head or if there's an oil additive that will recondition the rubber seals.  Any advice?

      My Moto4 project

      A few weeks ago, I foolishly asked my girlfriend about a quad that's been sitting under a tree at her parents' place for 25 years... This thread will be a sort of log of my attempt to resurrect it. I'm actually a computer guy, not a mechanic, so this will be quite conical for some of you, I'm fairly sure 🤣
      So far I've found out it's likely a 200. Not sure what year yet... The frame has a serial of 53J-001343 (I think). Engine appears to have the same number.
      We inflated the tyres on Saturday, which were still up today, so that seems a win. This also confirmed that the wheels do turn, as it rolled back into its 25 year old indentations as the 4th tyre started coming up.
      Oil looks used but otherwise OK. I'll change it if I actually get it running, but looks good enough for attempting to start it up again.
      Fuel tank had.... something in it. It smelt more like old stagnant water than fuel of any sort. Drained that out and flushed some clean fuel through to be sure.
      Fuel tap was jammed in the off position. WD40 and some force got it free. Did that after the fuel hose was off, so hopefully the carb isn't full of whatever it was in the ttank.
      Engine turns fairly easily with the rope start. Made typical exhaust puffing sounds.
      Unfortunately the rope mechanism was not fully rewinding, so I was limited to about half its length... And today it jammed fully pulled out. I attempted to remove the rusty screws, but one stripped it's head out. So for now the rope rewind is jammed.
      Spark plug connector seems possibly burnt inside. Black crap on both the plug and up in the connector, and the connector doesn't seem to actually stay on.
      Throttle lever is stuck fast. See photo for possible reason... Cable also feels jammed. I assume the throttle itself is jammed. That'll be fun given my skill level.
      Electrical stuff all seems dead. No headlights. No starter. No indicator lights. Could be a fuse. Could be bad connection. Not something I'm too worried about at this point.
      Front brake handle works. Parking brake clip thing was bent out of shape, but that's now fixed and working. Front brake only works on one wheel. Other one seemed rusted in place (off). WD40 and hammer got it free, although still stiff. Cable might be broken as it doesn't move at all when the handle is pulled.
      Rear foot brake works but needs adjusting.
      Other handlebar lever doesn't budge. Not sure if that's a clutch lever or rear brake... If this is the 200 version, I gather it's got a centrifugal clutch so it would be a brake lever... But I'm not yet sure exactly which model I'm working with. And the cables all disappear under the plastics and fuel tank and I didn't bother trying to trace where it goes yet.
      Thats probably about it for this post.

      I got the old thumper going.  My best guess is it sat in a barn for the past 10 years.  Now that I know it runs, it’s time for a valve adjustment and  tracking down a clutch cover.
