Bought my first new Quad! 2001 YFM400 Big Bear!

Recommended Posts



Finally got a chance to push around some heavy wet snow today. There was a bit of sliding sideways on the big piles but I feel like the tires have a lot to do with that. The plow held up good even slamming into these big piles to break them up (surprising with what little metal is mounted to the frame). 

I do have a few questions however. The back light comes on with the headlights, but the rear brake pedal or grip turn on the brake light. Is there a brake light on this model? Maybe the filament is blown for the brake light? 

Also, shifting seems hit or miss. I really need to pull up or push down hard to get into gear from neutral. I do feel shifting is smoother the slower I go, however. What are your thoughts on these things?

What I meant to say was that the light DOES NOT come on when rear brakes are applied

Not sure about the rear brake light, i will find out about that tomorrow for you and get back. 
As far as the sliding goes definitely related to the tires.  
 

Shifting seems a little rough on mine also. Im going make some adjustment tom and report back.

No brake light. I looked and double checked.  Even took the rear brake light apart and the bulb only has one element within the bulb. 
Also looked at the breaks and no switches are present.

Ahh ok! Thanks for checking, it's good to know my brake light switches aren't broken, but rather they don't exist!

Congrats on your new quad!

Thanks @erthsole, I think it's a great machine, even with its age!

They last a long time theses machines. Only thing that can truly destroy them aside from fire is salt water.  Other then that they can literally be brought back from the dead.

That's pretty incredible. I remember riding a little bit in my teenage years with a high school friend, years ago. He was big into 4x4s and 3 wheelers. I remember he would love to fix them up. After getting down underneath and looking around, this particular 400 is very clean underneath. There is hardly any rust, and I thought that was pretty impressive for being 18 yrs old. The carburetor looks great too, not sure what the inside is like but since it runs good, I guess it's OK. It looks to be the original (like the tires, ugh) but the idle control seems really hard to twist. I may need to try and replace that, or at least give it a good oiling.

They are a little tough to spin, as you turn that adjuster press the throttle a little bit. The  pressure of the spring/throttle pushing on that adjuster makes it tougher to turn.

Thanks for the tip @Frank Angerano I think I have it dialed in now. 

I'm glad I have 2 props on the price of this @pablo Blake I was initially thinking it was a little high, and I definitely wanted it since the seller said it ran. I guess there is always some risk buying through a private seller. But some machines are worth what a buyer is willing to give. In my opinion, if it's what you want/need and it isn't junk, then it was worth it. 

We got another good 4 inches today and I really didn't want to struggle with poor tires. I pressed on the almost completely shot tires and it really felt like there wasn't any air pressure in them anyways. Since I plan on getting new tires, I decided to get 300 1/2 inch hex head sheet rock screws and drilled them all into the tires. This Big Bear and plow tore up the snow on the property! So happy with how it handled everything. All in all I've already saved $500 in having 'our guy' plow the property, so by seasons end I think this ATV will have paid for itself in the end. In the spring, I plan on a long overdue grading of the lot too, it's pothole city.

Another satisfied customer!!! 
Very happy you like the bike, its too late now since you put sheetrock screws in the tires but they sell straps and or chains that go on the tires relatively cheap that would get you through the winter. Also pay attention to that driveway should you lose any screws !!!! You will wind up with them in your car or truck tires.

Definitely a valid point. I checked the tires after and I didn't loose 1 screw! I thought I would, and I might still... But I'll grab chains with those new tires in a week or so. Needed something in a pinch before payday.

      Unfortunately this weekend we waived goodbye to the 99 400ex.  Ported and polished head, DMC Alien exhaust with dual header, an absolute unit that would run 70 on the top end.  Fortunately though the 400ex left in exchange for a fairly cherry 98 Honda 300..the holy grail of reliability in a mud and water toy.  Previous owner added the snorkels and it was a decent job.  Put some 25" swamp witches on it, now it just needs 1" spacers, 2" bracket lift, couple of pinion seals and a pound or two of dielectric grease.  Hate to let the 400ex go as it was a gem, but it's hard to pass on a cherry 300.  These things are just so dang reliable and easy to work on.

      So I have rebuilt two top end's now and going through the process of a third.  I'm confused about how high the compression should be on these atv engines, and if low compression, what should be replaced or checked and how?  And as far as smoking, how to tell what is the issue there as well.  The first rebuild i did was on a kawasaki 300 and it turned out ok...  I realize that I adjusted the valve clearance on the exhaust stroke rather than the compression stroke which caused a tick.  nut the thing that got me was one both rebuilds, the compession reading didnt really change that much.  I've heard that engines should have over 100psi compression, yet have never seen 100psi reached on my tester by any engine.
      this thread is open to any top end questions btw.
