Ok,

I just got a pickup load of dirt, scooped it all outta the truck, and put it where I wanted it. I also realized that a pickup load isnt worth the trouble of scooping as it takes about 2 to even make a DECENT jump. So how do you get your dirt? Dumptruck?

 

we didn't haul dirt in we just had a dozer push it all up.

 

I say yall need to do some racin and get the hang of it u gotta go ***** out and preload the suspension when u hitt the face of the jump then if u come off the jump if u r nose divin u betta get on the gas if ur wheeling hitt the back brake and u wanna be on the gas when u land if not ur bound for a hard landing i race a 95 banshee decked out all lonestar and pep shox and hella lot more and im pretty damn fast so if yah need any info just reply later yall

 

hey man yah that double double thing or whatever u called it is acctually known in the moto-x racin world is known as a stepp up and yess cars work intill the dirt starts washing away then it could suck ive seen bigg cement tubes and round hay bails,wood,alot of different things work just try it and see lata,

 

When you pushed the dirt into jumps, didnt that lower the ground level? And with a lower ground level, wont it cause it to be a big water puddle when it rains? Seems that it would be like a big hole and turn into a swamp. We did this for my double, but only pushed the dirt up between the jumps so that if it become a big puddle, it wont really matter cause we wont be in it anyway. We can all clear it so no biggie. If it doesnt turn swampy, can yuo let me know some specifics on how you did it? Thanks a lot.

 

it workes good to make it a little rounded and it will shoot you aloso do you get compression jump a little and make the quads shocks compress try small first and find out how it works the best (the warror is front heavy). My mojave will jump good but it get to a point pretty fast where it wont jump higher towards my 250r that the faster and/or more gas you give it on the take off of the jump the higher and farther you go also i can make it go farther or not as far with body posture and try to land level so the front and back land at the same time (make a landing if you didn't).

 

Rhino99, sounds like a step-up to me.

 

I have seen people use anything from vehicles to huge steel storage tanks. Basically anything that wont crush under the pressure of the dirt will work. If you have a wooded lot with downed trees, try piling logs up in a pyramid fashion and covering with dirt. That works good. If using vehicles, it might be wise to remove the engine and fuel tank. The EPA frowns at burrying that stuff.

I have built my own ramp before, we used to have a ball with that thing! It was about 5' wide, 6' long and only 2.5' high. I added a 6" tall kicker to the top of the ramp, talk about launching you into the air! What made it so fun is one person could easily move it around to jump different stuff. Jump down hills, up hills, off of embankments, over things and over each other!

Keep in mind if you try this, the ramp must be VERY sturdy to take the punishment of being hit over and over by a 400 pound machine (Not to mention the G Force it will have to with stand). I used 3/4" plywood with 2x4 framing, 2x4 legs braced well. The kickers were a series of 2x6's cut into a wedge shape about 16" long with 3/4" plywood nailed on top. Screws would be the way to go if building another one, although the nails never came out or got loose. Have fun.

 

I have some pics of a large tabletop jump I have been working on. When it started out the takeoff was almost quarterpipe shaped. It really tossed the quad upwards. But, staying on the gas keeps the rearend from coming up. I am running a stock rear shock with stock settings. It bottoms out once and a while, but only if I over-shoot the landing and land on almost flat ground.
I haven't done anything to the take off since I first built it. I have only been extending and steepening (is that a word?) the landing so I don't bottom out so bad.

You can see pics and videos of it at http://www.uslink.net/~philzie/new.html

I hit it in 3rd gear, about half throttle.
