Would one of you long-time Attex owners out there help me out? What are the differences between the Chief and the SuperChief??? Looking to buy one in good condition, but need more specific info. THANKS

I own a 1972 400 Chief. This machine is really good. The machine has a 400 JLO engine and with my 21" rawhide III tires goes about 45 MPH on flat land. The machine has excellent power in the woods and can go over logs of just about any size. The machine is also great in the mud, (and I mean deep mud). There are however a few flaws in the machine. The machine lacks low end torque. If you wan to climb a very steep hill the machine wants to bog unless you get a running start. In the snow the the machine is slower if the snow is over 18" deep. Anything less than that the machine drives fine. The T-20m trans makes the 400 Chief an ease to drive can turn on a dime. The machine is very stable in the water and travels at a fair speed. All I know about the 500 Super Chief is that it has a bigger engine. And there is no replacement for displacement. The 400 Chief is a great machine but I hear the 500 Super Chief is good too.

Attex forever

jkemp,

Yes the 400 get's a big sluggish on the hills. I'm currently rebuilding mine and an going to replace it with a three cylinder 700cc snowmobile engine. Have to see how that improves things :)

Let me know how that turns out with the 3 cyl engine. I am considering purchasing a Max 4. I have recently rode one and it seems like a great machine. I just bought a new lower polyethelene body from RC for my Attex. The biggest problem I have with my machine is the chains. I keep stretching chains and they start to skip. I think the chains are getting dirty becaue of the cracks in the lower body. I think if I get that problem fixed (the chain prob) I will be stylin. Kemp

Kemp,

I'm working hard on the Attex I'll have to rebuild two axles from coldrolled because they were frozen on and had no choice but to hacksaw them off. No biggie. The three cylinder is 700cc and is a real screamer so we will see. I also am going to install a hyrdaulic brake system from two street bike front ends with rotors resvoirs etc. Definately a project :). Your chain problem is shared amound attex owners from what I understand. You have to keep up after the chains on the attex because the two stroke pulls hard at certain rpms and stretches the chain. The chain tensioners on the Attex don't hold much weight either. I'll more than likely replace them with something else when I get her back together. Also check the back of the Attex there are two drain plug holes low in the body if they are open then dirt and muck is going to get in there.

Pete6x6,
I had the same problem with my machine. I purchased the Attex for $500 from an old man. The machine was in his garage and had not been started for 15 years. I had to replace all the bearings and all the axles. The axles that were not bent I had to cut off. My buddy Garnet Lucier is a master fabricater and built me 6 new axles from cold rolled 1" steel. I have already bent 2 axles. I get a kick out of some of these guys praising these hollow axles on Max II. How can a hollow axle hold up better that a solid steel axle? Anyhow when I change the body over I am going to use a harder steel and make six new axles. Then my machine will be virtually bullet proof. Let me know when you have it finished I would like to see a picture. ..Kemp
