drag ex

[odog]

does anyone drag there 400ex i know it isnt a drag bike but people do drag so if anyone dirtdrag or race on a track wether its a 330 or an 1/8 im just curious to no your time and speeds and what kits you're running

[400exrider707]

search, I've seen more than a handful of drag EX's on here. Chad502ex would be the guy to talk to, he's built some big 400's. I dont think he's around here anymore though...

I figure mine runs about a 10.2 in the 1/8th. HRC 450r runs a 9.5.

:tired:

He wants drag 400ex's not stock piped ex's.



I know there was a guy on here with a full on dragger 460 stroker. Forget his name.

Oh im sorry i forgot the timing key lol.

Just makin a point. He's lookin for the bad boys. 460/500 strokers.

mac_ando hes got the drag bike with the 08 plastic on it...

i drag a 300ft sand/dirt track. i run a 5.3 with a 426 piston. does anyone have tips on lightening these bikes up? i want to drop like 2o lbs off.

[dunatic]

axle alone will do that.

Get rid of your 30# hunk of steel and install a JJ&A (11.5 lbs)

Then get a ultra lite swinger (5-7 lbs) in a +6 length.

The entire rear end of the my bike (swinger, axle, wheels, tires, sprocket and brake hub, sprocket and rotor only weigh 48 lbs.

Then mount up some spindle mount front wheels/tires, remove the front brakes all together, ultra lite stem, drag bars, lights, remove all the extra frame tabs, install a kicker and rid yourself of the battery....better yet, bump start it.

You can shed 40-50 lbs if you try real hard.

I have one 440 on gas that runs 5.0 and another 416 on alchy, with 30 shot of nos that runs 4.6 in a 100yds

ive got a 426 13:1 compression with the 41 fcr. ported with a st 3 hot cam. lightened flywheel and the air box eliminator. i have a +3 lonestar that is heavy as balls. i plan on tearing it down and grinding down the welds and cut a bunch of stuff off the frame. i really need that axle but 650 $ to cut weight id rather run and lose it myself. do you have any stroke? i know my crank is about to go so im looking into getting a 6 mil stroke with a hd rod to keep up with the compression. you know anyone who makes the 6 mil? another thing, my bike eats clutches every 4 or 5 rides any tips? i only run the oem honda because they seem to last the longest.

are you soaking your fibers in old oil first, and rough the steels up on the garage floor before they go in, just make sure they're clean.

[dunatic]

I dont know who builds a 6mm stroker crank....but try and call Poweroll in Redmond oregon.

As far as the clutch goes. A couple things.

CBR900 clutch plates. Barnett springs, scuff your steels over some 200 grit sand paper, soak your fibers in ATF overnight before you put it all together.

if you watch other forums like planet sand dot com, you can find an aluminum axle for $450 or less.

modquad makes one too

[mac_ando]

My motor is up for sale. it would b cheeper to buy than to build.

[odog]

so who one the race in the vid

[mac_ando]

unfortionatly he did by about awheel length. I have beat him on 500ft

dunatic.......looking at a bottle set up now, you runnin a wet set up or boondockers?

[dunatic]

I only run WET setups.

Ive done 9 so far.

3 - Raptors
2 - YFZ
2 - 400ex
2 - Banshee

I like the Nitrous Express Piranha the best. I dont run their fuel pumps tho, so your better off buying the parts and building your own system. All the NOS fuel pumps out there are cheap and within a short period of time they fail. I run a good ol electric Carter pump from a Chevy Chevette....but it at Napa for like $47 (versus $85 for a replacement from NX or NOS).

I also only do "Blow Thru" setups. Meaning I blow the mix thru the carb. The biggest issue with NOS is the leaning condition that will occur when you engage it. By blowing thru the carb your assisting the carb to work better by increasing the volume and velocity of air flowing across the emulsion tube, thus the carb is supplying more fuel as well.

Keep your fuel lines as short as possible to both the solenoid and fogger. Fuel is only under 4-6 lbs of pressure, but NOS is 900+. Which do you think is going to move faster and easier ? NOS of course.

My tradmark is typically "Sneaker" setups as well. I like to hide everything if I can. I wire the micro switch either in the thumb throttle housing or on the side of the carb. Ill wire a "activation" switch into the headlight circuit, so the rider only has to turn the bottle on (buried under the seat in the air box) first thing of the day and going riding. When he wants a lil extra UMmmppf, turn on the lights, give it full throttle and a way you go.



Here the bottle is mounted under the front plastics. Look closely and youll see the front nose piece is cut so it can hing when you remove the 2 screws to refill the bottle.

In this pic you can see we built a box to hold the battery and electronics in. What you dont see (or is really hard to see is the wad of black tap wrapped around the wiring just above the relay. See the kinda squarish item wrapped up ? The banshee never had a battery and it only produces AC current to the lights. Well we needed DC to the battery to charge it. So we built a converter using a diode (one way circuit) and a relay, thus converting AC to DC from the low beam head light circuit. This bike only has single beam driving lights.

If you look closely you can see the wire zip tied to the throttle cable. We mounted a micro switch in the thumb throttle housing to engage the NOS at full throttle only. Keeps it out of harms way, inconspicuous and one less thing the rider has to think about to use it.

These next two pics just show what I mean as sneaker systems. We totally encapsulate the system under the seat. Unless you notice the longer, slight deeper air box, nobody the wiser less you tell them.

The first time runing the blue YFZ at the dunes, I lined up at the bottom of this very large tree trail. We call it Banshee Hill. At the bottom its open and wide, but half way up everyone's gotta give and follow each other thru the trees to the top. It's a great place to race and see whos got the stuff and whos wearing the baggie pants carrying the brass between their legs.

Well, I had been racing there for about 30 minutes when this guy shows up with the gal pal on the back of his BRAND NEW yfz, with every bolt on device the stealership could sell him. He had all the right gadgets and the bike was fast. Then he put is lil blonde haired chicky that weighed probably 90 lbs soaking wet with all her clothes on to ride it. Up until that point I didnt need the JUICE. I could out launch him and stay just enough ahead of him that he couldnt get me at the tree line.

His lil gal tho was a different story. She could do to me, what I was doing to him. So I let her win a couple of times, all the while he was at the bottom giving his bud's high 5's telling everyone how fast his bike was.

Then I switched the NOS on. we launched and I ate her up. Id let out just enough so that she was close, but not close enough. We do it again, and the same results would happen. Then on the 3rd run I railed her. I got her off the line, up to the trees and sprayed NOS all the way up the hill.....just roosting her with sand.

He was furious at her.....he was trying to give her pointers about launching, shifting gears and shifting her weight.

So we lined up one last time. This time I launched, wheelied almost all the way up to the trees and smoked her good.

At the start he was standing directly behind us and caught a glimps of the LARGE air box. When I got down the hill is when he asked "what have you done to that bike ?" I just told him "a few lil bolts on's" and lifted the seat to show him. That bike I set it up with just a 20 shot. The black YFZ had a 25, the banshee a 40 shot, my orange EX has a 20, the purple seated EX on alchy ran a 35 shot.

Great thread...you just gave me a few ideas! how large are the bottles 10? How long do they last on the 400. I'd be on the damn thing all day!I'm goin to get mine dyno'd soon. Want to see where I'm at before I do anything more....hope for low 40's. I want to add a 20shot to it or switch to alky or both. thats a good idea WITH IT IN THE AIRBOX, dont think the 400 has room. Any systems you recommend. I like having a bike that shouldnt but does.

[odog]

yea great thead but how does the nos compare to a turbo

14PSI turbo on a 400ex was more than doubling its HP.

The BIG bottles you see are 2.5 lb, but the one on my bike now is only 1.5 lb.

Depending on the size of the shot and how long you plan to hold it, will determine how long the bottle will last.

The key to any NOS system working well is keeping the line pressure up. In the old days you would see guys heating their bottles with a torch at the starting line, using bottle warmers, etc. That is ol skool now.

Just get a bottle with no straw and a high flow valve. When full, the bottle will have 1500-1750 psi....you need to keep at least 900 at the solenoid at all times. Less than that and it's empty and time to refill.

Now I refill right at the dunes. I use a 10 lb bottle and keep it in the truck near sunlight so that it's bottle pressure is as high as I can get it. Then I do whats called a gravity fill. Connecting the two bottles together, leaving the hose just slightly loose on the lil bottle so that some gas can escape and the liquid will fill into the bottle. They never totally fill it up, but 70% is all I need for 4-6 seconds hill shots x 10-15 passes.

On the big bottles, you can spray it a lot for an hour, then have to refill. But for drag racing, you should be able to go all day on one bottle making 10-15 sub 5 second passes.

the rear of the EX just doesnt have the room for a LARGE air box that will hold a big bottle. You could put a pair of .75 lb bottles like the ones that the rice rocket Ninja / Hayabusa guys run. That would be expensive by the time you plumb and pay for all the hardware to do it.

I like the Nitrous Express systems the best. Their solenoids hold up to high vibration and their fogger angle design just works well.

The turbo is going to have lag and youll have to combat the heat issue and jetting is pain in the ***. It never needs refilled tho.

The NOS keeps your motor cool, no lag, but does need to be reloaded every so often. Not to mention, you dont have to rejet if your NOS system is tuned correctly.

[Chukkinsod]

not to mention the price tag is nearly 1/4 that of turbo. I was going to run 2.5 bottle. Does the timing need to retard or advance to run these blow thru set ups? Dont want to send my motor to the heavens the first run I make. Lookind at the NX express set up........anyone have a used set up they want to sell

[dunatic]

that is my system of choice.

I dont do anything. I install it and follow the tuning instructions NX provides.

Check planetsand classifieds...both 2 and 4 stroke.
