400EX oil level with FST oil cooler

Recommended Posts

My 500EX motor was already broken in and heat cycled. It was sitting for a month with an occasional start and idle.

After a hard ride at a mx track I checked my oil level with engine oil temp at 250* and the motor shut off. The temp never went higher than 250* (cooler works great!) The oil was near the top of the tank. I let it cool down for an hour and the oil level was at the top of the crosshatch section (max full). I went back out for about 20 more laps and went back to the staging area and the oil was seeping out of the dipstick o ring. i have an aftermarket dipstick with a temp gauge on it. I removed the dipstick and oil started to overflow.

I havent ridden it since then (no time) but checked the oil and its back down but above the full crosshatch area. I dont smell it but could it be possible that gas ended up in the motor from a sticking float. When I towed it to the track I forgot to turn off the petcock and actually left it on reserve. its now shut off.

after about 40 laps I have about 3/4 of a tank is this excessive or ok?

      should i run a thicker oil in a older quad because it make a little more noise than usual

      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.

      I have a 2016 Arctic Cat 500 and recently noticed some oil leaking on the engine block to the right of the oil filter. It's near two metal lines going in and out of the engine block. I think one of the lines is called an engine oil line. I have a photo I'm going to try and attach. Any help would be greatly appreciated. I don't want to start tearing into the engine if I don't have to. I think maybe a gasket or something blew around one of these lines. The ATV runs fine otherwise. Doesn't overheat or anything.

      Hi everyone, I received a 98 Yamaha Timberwolf from my brother for free, and I'm working on getting it going. 
      I am having the following problem: 
      The engine is backfiring through the carb. 
      I have done the following to try and get the four wheeler running: 
      Rebuilt the carb and set the air screw to 1-1/4 turn out and the circlip at middle position 3
      Replaced the coil, because the cable was loose at the coil end
      Repaired the main ground, coming from the battery
      Replaced the ignition switch, because my brother couldn't find the key. New switch tested good
      Tested the kill switch and it tested good
      New coil tested goodfor both primary and secondary coils
      Pickup coil resistance is at 195, which is correct
      My source coil, is where I believe the issue is. The resistance is 310ohms, and it should be between 428-523ohms
      When I opened the stator housing, there was significant oil, which I have read is normal. Does it sound like I'm on the right track replacing the source coil? Could this be causing my backfiring issue? It looks like the source coil is part of the stator assembly, is this correct? 4BD-85510-20-00 STATOR ASSY
