Too much power????

[Frymechanic]

Ok. So i got my attex running just long enough to shred the stock firestone ballons off of it! While it was a very fun ride, it is now an expensive repair. So before i go and spend a few hundred (if not thousands) on new wheels tires and adapters i thought i might rethink powerplant! Im not exactly sure of model because of the year they seem to all be same except motor it came with and the one thats in mine is hardly stock. It has a yamaha 433 twin 2stroke and i thought that this might be a bit much at first especially for a skid steer design but i saw the brochoure section and relized that some came with motors that big and is capable of 40-45 mph. While fun, can be a bit scary if a lever is pulled wrong at or close to top speed.
After some rumaging i found one of my old project motors, a 11hp honda single. Thought it would be much tamer but is it underpowered? If i decide to put it in, do I have to make spring mods to the clutches due to lower RPMs? It has a Borg T-20 so im sure nothing is wrong with it but if changing motor should i rebuild it to undue any torture marks that the 433 may have left? How do you know when a T-20 needs a rebuild?
I want to be able to take this thing most places and have plenty of power to climb anything as well as have a little speed so im not left behind. Any advise would be great. Thanks!

First off, there are people running 3 and 4 cylinder car motors and the T-20 holds up just fine......these are bulletproof units and they're the best AATV transmission ever built. Next, it's completely possible to tear balloon tires off the rims, ask 6X6World member Don about his green Attex Superchief. Also, the only way that you'd spend in the $1000 range for a set of wheels and tires would be if you overpaid and went through Route6x6. There are MUCH cheaper alternatives that we can point you in the direction of here on 6X6World, just use the search feature on the site and you'll see. You would need a new drive clutch since the shafts are different on the two engines that you discussed. The driven clutch on the T-20 needs a 4 stroke spring on it as well. You can buy this directly through Recreatives. Amphibious Six-Wheel Drive All-Terrain Vehicles: MaxATVs - Call 1-800-255-2511. The 11HP engine might be a bit underpowered, but for just putting around it might be alright. I'd probably recommend at least a 14-16HP Briggs Vanguard to do what you describe.

So if I just put some better wheels and tires on I should be ok with the two stroke? My thought was that the stock balloons where just way to thin and soft for that kind of speed anyway. Plus I live in the desert so I'm in the sand a bunch and they did nothing helpful there. I'll keep an eye out for a better engine choice.

[jpswift1]

Yes, I'd start with new wheels and tires and you will be in good shape.

So what kind of tires should I find? I figure at least a 6 or 8 ply to handle the power.

I think you are missing the point....Your balloon tires were 30+ years old. Rubber compounds have come a long way since the 70's, but tire mfgrs still say tires are only good for 7 years.
Any modern tire will be fine for you, pick the tread pattern that suits you best.

[jpswift1]

Buggyman is absolutely right. Any 21x11x8 or 22x11x8 tire on an Attex should work just fine for you on your Attex.

OK, I figured as much but you have to understand that i live in the desert meaning lots of rock and stuff that likes to shred tires like toilet paper. I know there is a wide variety of tires i can put on it but wanted to know if there was something specific for me to look for? And if the two stroke was too much for the machine? I don't really think it is just seems to be rider preference. But thank you for the info guys!

There's no such thing as to much power!

Whipper

Gotta go with Whipper on this one. You can always squeeze the throttle less, but if the machine is under powered you will get into a situation sometime where you wish you could squeeze it more.

When Whipper & I would ride with ballon tires in our desert, it wasn't the rocks that were a problem with the balloons, it was the thorn punctures we would get just about everytime out. The Gumby Trail ride was one of the worst sharp rocky rides that I went on with him yet. The Rawhides II 's are great for our desert terrain. They don't make them anymore, but that doesn't mean there aren't a few out there anymore. Or get the best tire that is at least comparable to them for rocky terrain, if you don't want to be dissapointed in the middle of no where someday.

Too true! No such thing as too much power! Lol!

Very true! There were more patches on those tires then i care to count when i found it. The major issue im running into though is that when you have enough power to break the tires loose and your in sharp rock (and thorny stuff) it slices tires like a hot knife through butter. Initially i was going to dumb down the power but it was too fun with that motor and i dont want to go through the expense of converting. So besides the Rawhide IIs what else do you recomend?

Now to jpswift: What alternatives do you mean? And how much do you think I should expect to spend for a full set of 6 tires and wheels?

Clark will charge you close to $1000 for a set of wheels tires and adapters, which is absolutely rediculous. Read this thread......it'll save you some serious money.

Well so far for what I want on the cheap, I'm looking at approx $600 from Motosport outlet. Now if i change a few things (choices) i can maybe get it down to 500. Which i suppose is reasonable considering there are 6 of them. Could be worse, Could be replacing the Argos 8. LOL! Does that seem reasonable? After reviewing your link I see i could change to the 5lug 8" trailer wheels but then the tires don't seem to get cheaper. IDK, maybe I'm just nit-picking too much and just need to make a decision and do it. After all a machine is only as good as the parts you put on it!
