Pictured are the tubes for your fuel vacuum activators. You might not have the horn in the center depending on your fuel tank valve.

In the back top, two vent hoses that route up underneath the shift lever panel.

Fuel feed goes in lower left near the bowl.

Tim : thanx alot ! i dont understand all the extra hoses? as they go nowhere ? venting maybe? jim

Fuel pump should be on the upper left frame fwd of the handle bars. It is the vacuum that operates the pump.

You might not have the fuel tank valve port on your carb. If your tank valve is the simple on, off, res, type, you don’t need this. If it is the on, pri, res, type, then there is a vacuum port on the back side of it. Vacuum from the carb opens this type valve to allow fuel to flow to the pump.

If you have the simple valve with a carb that has the fuel valve port, plug the carb port. It is not needed.

Do you have a manual for this machine?

      Have a 1998 AC 300 2x4, Just installed a new carburetor. Engine starts easy but the choke RPMs are very hi and take along time (5-10 mins when cold out). After engine has warmed up choke releases and it idles and runs fine., It does no have an electric choke. The choke lever is never used and it seems like an auto choke? Long story short, how can I lower the choke rpm levels?
       
      Also, carb came with a spare145 jet, not 100% sure what is installed. Could this impact choke RPMs?
       
       
      Any help and information greatly appreciated.

      Hello I’m new here and was wondering is anyone knew of good replacement part numbers for front struts and rear shocks for this atv? I think I’ve found a new rear shock, that looks like the original but there is no dimensions or anything and was wondering if there are any afterMarket new front struts available. I know it’s a long shot but any help would be appreciated.

      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.

      First issue was fuel pump wont start once ignition has been turned on. Replaced the pump as I had one on hand, than noticed no power so replaced the fuel pump relay as that was were i traced the power to. Still nothing so further inspection looks like signal is coming from the PCM (FLR B20) but not switching the the brown wire to the fuel pump. Ive checked the operation of the bank angle sensor and it appears operational. Fuses and wiring all appear OK. The engine stop relay also tests OK. Ive been through the repair manual and diagrams but to no avail. Fully stumped, any tips would be helpful. Thanks

      The choke lever doesn't stay in position on my 2001 Yamaha Kodiak.  The model is YFM 400.  I have to hold the lever to the choke position manually for some reason.  Any Ideas as to why?
