New Homebrew Projects To Try - Homebrew ATV's

[Welby]

Check out this website I found! ###Don't know about you, but I am definitely inspired.

Does anyone know of any other info on the web about homebrew ATV's?

Cool stuff! I wish I had the time to do that sort of stuff. I guess if I quit doing some of the stuff I am doing now, I would have more time...but if I had more time, I'd find more stuff to do, so I wouldn't have any time....help me, please help me %)>

Welby - how do you find this stuff? ###I surf now and then but I seldom come up with neat things like this. ###Thanks for sharing.

This is my own creation I call it a RIOT[real intense offroad toy] ###It has massive amounts of power and long travel suspension.
my next project will be like the mini monster 4x4's at http://www.patriot-racing.com also do a search on the web for "The Edge"go kart plans[ they are the best]

Alright 'yoteee, when are you going to share the details of your build? ###

That Patriot Racing website is wild. ###Thanks for sharing.

[coyote]

well welby what do you want to know...I'll keep no secrets here. ###I have thought about having the frame cad drafted but I think it would cost $$$$ and that would mean recovering the cost. any simple cad or drafting programs you know of?thanx yoteee'

Coyote,

I believe I could design the chassis itself pretty well. ###A well layed out design with plenty of triangulation like yours should do very well.

What I am most interested in are some tidbits on the details such as suspension, powertrain and brakes.

What kind of motor and transmission did you use? ###What kind of half shafts did you use to achieve that independent rear suspension? ###Also, where did you get your brakes, and are they disc or drum?

Finally, I am very impressed with the looks of that suspension system. ###That thing looks to have a ton of ground clearance and wheel travel. ###Is that suspension system of your own design? ###I would love to know what shocks and springs you used as well as take a look at some pictures that show that detail a little more. ###Personally, I think a well designed suspension makes or breaks an ATV of any kind.

Good Job!!!

Oh, and on the CAD program...years ago I learned a little CAD by using some high dollar AutoCAD software that was provided to me by another contractor. ###At the time this stuff was the real deal.

About a year ago, I happened upon some software sold at a local Office Depot that was called IntelliCAD and I think it was only $10. ###Shareware type stuff really. ###Well, not really - but you get the idea.

Anyway, I get it loaded up on my computer at home and, lo and behold -- it's the same as the high dollar AutoCAD I used about five years ago. ###It does great 2D drawings, but it does have 3D capability. ###If you can find it, it is well worth the money and will do everything you will want it to do.

I guess that's what happens to software that becomes obsolete. ###It gets renamed and marked down to $10 and then gets sold at discount stores.

Welby,
This was my inspiration the XRV. ###This site had only one pic on it last spring and now there's alot to go by. ###I wanted more hp and more travel besides they're in Austrailia and expensive. ###They have brigs and straton 22hp engines in them as well.

I have single A arms with truck coil overs front and rear toyota corrola real coils with the truck coils as well.
Drive shafts are eccentric pto shafts from tractors and winches.
Trailor front spindles with 4x4" rim
Rear hubs are chev sunbird tapped to 4X4". ###Spines are cv's chopped off.
engine is liquid cooled 462 rotax. ###Comet full race clutch...artic secondary...1 1/8 layshaft #50 11 tooth sprocket to pilot axle and final drive sprocket 60 tooth.
Hydrolic clutch slave nissan 300zx to 8" disc and atc honda caliper.
This was a cheap project really compare to a performance quad.
The suspension is very good. ###I have taken ditches and jumps of 3-4 feet and smooth them out. ###And really when your sitting flat on your butt it will break your back other wise....hope this helps.

Thanks for the info coyote. ###I bet that Rotax is a screamer!

Curiously, what size and gauge tubing did you use on your chassis?

[Welby]

Dadgummit 'yotee! ###I just looked at all those pictures of your buggy, and that thing by far is the best looking buggy I have ever seen. ###That thing has got to be tons of fun!

[coyote]

Thanx welby, That's why it's called a Riot!
I really get alot kids hounding me when I puller out. ###
I chose mild steel 1x1 rhs 1.00 wall. ###[Can. steel is metric]
1.5x1 x 125 top rail.
1.25x100 rollcage
This thing is light. ###I will weigh it up this spring and try to figure the power to weight ratio. ###Should be equal to a fomula one car. I bought a hand held gps so I'll get some accurate speeds as well.
Rack is out a hyundi pony chopped down 2'.
I've got a mxz sled and had racing quads in the past This is way more fun and It's like our cams its just plain rewarding to build...yoteee'

Just courious coyote ###but how much did that cost? And how long did it take (hours)?

[coyote]

I did the rolling chasis and painted it in 21 days from a sketch on the shop floor. ###That includes chasing parts and several revamps. ###
I took one whole week off to do it and the rest of the work is weekends when I can.
I would think I have about ??? $3500.00 [can.dollars] ###All parts are new and Two thousand is just the motor and clutches.
Wheels + rims 700 bucks...it all adds up ....seat harness, steering rack ,steel...It may be more than I think...I don't want the wife to find out ...I better stop thinking...yoteee'
