Zuk's are a hoot. I really miss mine. I have a friend with one now that we had out at Glamis this Spring, and it was fun. His is completely stock and he was carving the bowls like a pro. It fits in his toyhauler with no problems. As was already mentioned, there is a ton of aftermarket support for them, I'd recommend starting with www.calmini.com.
There was only one size motor available for the Zuk's, a monster 1.3L 4cyl, but it did come in both carb and EFI. Go for the EFI if possible. Also, try to find factory a/c. The a/c compressor can be used as an onboard air compressor for tires and such. Check the floorplans for rust and look for cracks in the frame. Check the rear shackle mounts on the frame because they have a tendancy to break. Check the doors and rear gate gaps, the bodys tend to warp a bit if offraoaded heavily. Check to make sure all the electrical stuff works, the wiring harnesses weren't very durable. Make sure it's 4x4, there were 2 wheel drive models available, and be sure the hubs lock and the transfer case shifts into 4wh and 4wl. For $3k, you can get a pretty nice one. I see them for $1500 all the time. The one my friend bought was $700.

 

I love Suzuki quads, but I've never been a fan of the Samuri, or any Suzuki automobile for that matter. My neighbor had a Samuri and he had tons of problems with it, especially the transmission (it was a manual but still gave him problems!) Plus, I'm pretty sure my quadzilla had more HP and torque than it did. (I'm joking of course, but it probably wasn't too far off.) For my money, older Ford Bronco's or Jeeps are the only way to go for serious off roading. Just my $.02.

 

If i could get a jeep down a 4 wheeler trail I would get one.

 

If you can get a Sammy down the trail you can just as easily get a Jeep Yj down it. I think you may be slightly off in how big a Samuri is. I Stock Yj is no more than 62 inches wide at the wheels.

 

Tread width on a Samuri is 51.6 stock. My 400ex is 50" so I could see it on some more open quad trails, length would be the problem because of some of the tight turns. It would definately go places the Jeep wouldn't though.

 

I must correct myself. A quadzilla actually does have more HP! According to this website I found, the predecessor to the Samurai had a 1 litre engine with 45 HP and a top speed of 68 mph. (Stock zilla - 51/52 hp, 79 mph). The later Samurai's got a better engine with 64hp which bests the Zilla, but a good port job and aftermarket pipe on the zilla and you're there.

Here's the article for anyone interested.

yeah no kidding. what do you mean when you say atv? are you talking about the yamaha rhino or the polaris ranger. i guess i could understand that. but sorry, i think most atv's are A LOT smaller and weigh a ton less than that samuri. the samuri is a small car. are we talking about the same thing. im getting a little confused. 51 inches wide?

 

Actually yeah, the track width of the Samurai is just about 52". The widest point of the body is 60". My mini buggy is about the same size.
As for an ATV, a Raptor 660 is about 44" wide, add a-arms, and a wider offset wheel and you're easily hitting 50"+, about the same track width as a Samurai.
You could literaly park a Samurai in the back of a long bed truck....

 

You have to see one up close they really are smaller than some of the new quads. They can defintly follow a 4 wheeler through most trails where a wrangler or anything else would get too wide.

could you name some of these quads that are larger than the samurai.
