No clatter all smooth

if its sucking air through your tail pipe i would check and see if when u try and start the bike if the carb pushes gas into the breather then you know their is either a whole in your piston, rings are shot, or your intake valve is stuck open and the head is pushing air instead of sucking from the carb and out the tail pipe. compression problems could be as simple as no plug in the bike bad piston bad rings anything of that nature check your carb and see if its pushes gas into your breather when you try and start it then let me know what happens.

      2002 Quadrunner 250- Knackered cam and journal/"bearings", difference between 2001-2002 part and 2000 and earlier
      By kiriyaaoi
      Hello everyone, I just picked up an 02 LT-F250F the other day and have been in the process of tearing it down to fix some stuff- one of which was the cylinder base gasket leaking like a sieve. Well, I know why that is now, and I also discovered that someone had been in there before. I didn't take pictures, but it looks like it was probably run low on oil at some point, the cam journals and the "bearings" (for lack of a better term) in the head and the valve cover are totally wiped out, very deep grooves.  From what I know it's very difficult to repair aluminum in this way, so I'm trying to figure out where to go next.
       
      1. Have someone grind down the head and valve cover and fit actual bearings in since the aluminum is screwed, and have the cam ground down to match.  I have no idea what this would cost.
      2. Buy a replacement head+cam+valve cover.
       
      #1 I was hoping someone might have some advice on, but #2 seems like it'll (probably) be the more cost effective option.  However I'm running into some difficulty, it seems like the 2001 and 2002 models specifically use a different head part number,  11100-19B10, instead of  11100-19B01 like for all earlier models.  What exactly is the difference between them? There are obviously far more of the earlier heads because it ran for over 10 years.  Are they actually interchangeable? I've also noticed there are heads from the LT250EF that has 4 valve heads but also otherwise look identical.  Would those work as well possibly?  I'd like to not have to drop $500 on machine work or new heads on a $1300 quad that I'm already putting a bunch of new parts on.  Oh, and it has a new piston and the cylinder itself looks pretty good too, as I said someone was in here before me.
       
      Any help or advice would be greatly appreciated. I'll post pics of the carnage tomorrow.

      Have you ever purchased a quad from an impound auction?
      By DarkRider
      This is something I'm extremely curious about. Has anyone ever attempted to buy a quad (or any other vehicle) from an impound lot? I've always wondered if this could be a bargain, or a waste of time. Google searches do turn up some helpful results. Looks like the state of NJ holds auctions online which I'd be a bit hesitant about.
       
      My online searches haven't really turned up any results of anyone buying an ATV this way. I'd be really curious if anyone tried this, or knows someone who has. I've actually found a couple pages with online auctions for my state, but none had ATVs.

      I am in the process of puting it back together after replacing the DPS gearbox.
      The manual I have states that it will need to be flashed by a dealer. Is this still true?
      Also , I have a mystery bolt That I cannot remember where it goes. M6x 70 or so.  Hex head with a flat washer.I will try to attach a pic.
      Pic is no go for now....Cox issue I will try again later
      TIA

      Thanks for having me.

      Hey all, Thanks for having me in the forum. I just purchased my first ATV and am stoked to understand more about it. 

      The first stupid question will be, what is everyone's maintenance schedule? DO yo follow the recommended intervals or build one yourself based on the machine. 
       
      Thanks in advance.
