mine are ajustable and I run them as close to stock as I can if you could get it at 3-4" that would be fine .

the longer the swingarm the less traction you will have, unless you are hillclimbing then you need it to keep the front end down

thanks for the info. I have this quad sitting at home I was going to build a drag bike out of it (been on quads for along time) but after riding the 500 around I bought a couple months ago, I feel more at home on the motorcycle. I want to build a drag bike (buy another 500) but didn't know on the swing arm deal. It's hard on these motorcycles to launch good with the stock length swingarm especially if the start is on flat ground. We don't have the length of dune hills in Oregon like you guys have in Cali so the start is everything.

I dont like getting out dragged

The way I figure I can spend $300 on a carb and $200 on a pipe to have maybe 3 more horses or I can spend an extra $100 and have 25
better think of a good game plan son . wont be long before the extended '00 is back together kicking ass and taking names. drag ported, alky and drag pipe . which reminds me the motor has been gone 1 month, should be about done or getting close

getting out draged ....... most of the time its the rider, take a look at Paul or Robbie those guys are built to ride . now look at me @ 280lb I need all the fricken help I can get just to keep up with stock bikes so it dont bother me to much any more to get beat by a hopped up motor.

I have motors built my the best builders for Hillclimbing not sand drag racing, they run great and I ride the crap out of them in the sand and shoot the juice to em now & then not too offen because I dont race em alot. now if you put one of my kids on a bike they can rip on a stock bike .

If you are wanting the best of both worlds shoot the Juice I think its more cost effictive, but you still need a 41 mm carb

thats what i need to get figured out is the swingarm lenght. i had it abit to long last time i rode it. i was dumping the clutch full throttle and it felt right at home. ill try it alittle shorter next time and see what happens

LOVEMYCR500 wrote:this is alittle off the subject but for a dune hill drag racer, what is the average extended length do most of you run on your swingarm? I would assume it's mainly to launch and keep the front end down. Is 3-4" enough or is it more like 6"?

theres no magic number on the swingarm lenght for sand. so you will want an adjustable one. theres alot of variables that will go into determining where you run it. number of paddles, rider weight, how much power the motor is putting out, gearing

Slomo · Post by **Slomo** » October 2nd, 2007, 5:27 pm

If your going to extend it- do it right ONCE...
Make it adjustable out to about 72".... just incase you grow a set and wanna race some real bikes up some real hills.

If you run alcohol, run nitrous also. you can squeeze even more

better not see you get spanked by anymore flatbillers in glamis BRIT

well, I'll let you guys know if he gets smoked by any flatbillers this weekend at Dumont! Since none of you will be there to see it

Hey 100, at what length over on your swingarm were you launching full throttle and not having the front come up? I know there are alot of varibles but it's the starting point that I'm interested in. Just figuring the bike will run a 10-12 paddle tire and have say 70 HP. Is 4 over long enough. I would get one of the adjustable units if I did it.

lewisclan · Post by **lewisclan** » October 3rd, 2007, 9:13 am

I have one maybe 3-5" over stock GSS ajustable custom made swingarm.
Am running billet basket & digger clutch. GSS ported cyl, milled head, & race pipe. 41mm polished PWK, S/H CDI & compression release. C-12 & Boondocker 20 hp shot of Nos. 14-45, gearing 18" 16 paddle scat trac VIPER, Flexx bars w-inserts, 3.5" bar risers, 8" soltek light.
(I LOVE THIS BIKE FOR THE SAND)

Another one maybe 6.5-7" over Loomis built ajustable swingarm Billet basket & dirt digger, Lommis built top end ported & milled head, 41 Pro polished PWK. & GSS Race pipe, Boondocker 25 hp shot of Nos & C-12
14-47 Gearing 18" 16 paddle scat trac viper

Another one closest it will go is about 7-8" over stock ajustable swing arm
GSS top end GSS CDI. PC pipe, 41-mm pwk, boondocker 20 hp shot & C-12, 14-50 gearing 12 paddle domanator (domanators Not recomended for the sand) I may thow on some other wheel & tire for glamis a 12-18 paddle hooker

lewisclan · Post by **lewisclan** » October 3rd, 2007, 9:29 am

with an extened bike you want the front end comming up .... you just get your self over the bars alittle more to keep it down. otherwise you will be losing to much traction & wheel spin on 70" WB bike in the sand. you want to run it short just to where you can still have controll

you wont know where your bike needs to be until you get it dialed in and spend some $$

LOVEMYCR500 · Post by **LOVEMYCR500** » October 3rd, 2007, 10:26 am

lewisclan, thanks for the info. That's just what I needed. How do these machines run against the big banshee draggers at Glamis or at Dunmont? You never see bikes at the drag hills up here in Oregon that can compete and I think it would be alot easier and cooler to build a bike to do this.

Boy you guys love the NOS. How many runs up the hill can you get out of a 2 lb bottle?

Ported&Polished · Post by **Ported&Polished** » October 3rd, 2007, 10:46 am

I think the reason the bikes can't compete is because of several things. Rider ability is number one. Stability is second. And traction is the other. Quad riders have it easy, they just lean forward and punch it, bikes need alot of gettng good at. Quad stability is incredible, that's why they are so popular, anyone can ride one, a bike means work. And the traction a quad gets can not be matchd by a bikes skinny little tire, the quads have big fat monster paddles that hook up like mad.

I get my ass handed to me, some of those guys have 15-$25,000 in the quads. the last time my kids raced some hot rod quads @ dumont on banshee hill they got beat bad ...... banshees where clocked @ 80 & our bikes like 50-55 at the top

lewisclan · Post by **lewisclan** » October 3rd, 2007, 11:03 am

I use 20oz bottles under the rear fender and could do about 6 runs on a bottle hillclimbing a 300' hill

britincali · Post by **britincali** » October 3rd, 2007, 11:09 am

I used to think a CR5 could eat a banshee untill I watched those ones at dumont, they were friggin INSANE!!!

There is no way in the world you are gonna get the launch against a quad no matter how many paddles or what extension you have, the only hope I see is running the bastards down half way up the hill.

Theres no way anyone here could run down those dumont alky banshees tho

LOVEMYCR500 · Post by **LOVEMYCR500** » October 3rd, 2007, 11:34 am

yea Brit, you are probably right on the launch thing. Lewisclan, I'm suprised at the top speed, (50-55) were your kids hitting the NOS? I would think with your mods on the bikes you have plus the 20-25 shot you bikes would be hitting the 80-90 hp range with a great rpm range (8500-9000) I'm not that smart though and my butt doesn't judge speed to well.

I was at Sand Mtn Utah once a few years back, and they were doing speed trap runs up the main hill there. This hill is long. A guy there with a CR500 on alky hit 90 mph up that hill. It is about the same length as the main hill at Dunmont from what guys I have talked to said. I don't know what gearing he was running though.

The banshees these days are making some incredible HP and are as light as our 500 motorcycles in the drag chassis. It's going to be hard to catch a 120 hp banshee I guess. Gear it for speed and hang on.

britincali · Post by **britincali** » October 3rd, 2007, 11:51 am

I wish someone would have got some vid that weekend, if I were to read about it on here I would call BS, you would not believe how fast those things were.

It was to the point that I was amazed the riders were able just to hang on. I would guess they were 200+ HP, they were launching in third and 60 footing faster than any car-truck Ive seen running at a track.

britincali · Post by **britincali** » October 3rd, 2007, 12:35 pm

Well Im $502 lighter now, the cold fusion kit and fuel pump should be here on friday.

dannygraves · Post by **dannygraves** » October 3rd, 2007, 12:38 pm

F@#$ YEAH!!
too bad it won't be installed and dialed in in time for this weekend

britincali · Post by **britincali** » October 3rd, 2007, 12:39 pm

Slomas PM me your addy and I'll send you a throttle.

lewisclan · Post by **lewisclan** » October 3rd, 2007, 12:39 pm

I think Slomo is using one of those kits is that what paul has to?
so are you planning on having it on the bike for your this weekend ride or for the glamis ride? what about your carb?
