Ok,
We got back from a week at Glamis Saturday, and had a great time.

Now its time to start getting the DS ready for the next outing.

I have done the following to my 2000 DS

Intake = TM 45 carb, no airbox ported intake No Toil filter.

Exhaust = My Redneck slipon.

Big Gun CID.

15x42 gearing with aluminum rear sprocket and aluminum sprocket hub.

22x11x10 Sand Stars rear tires, 3psi.

23x7x10 AMS Blacktail front tires, 4psi.

Here are my questions.

1st: When people say they gain several lengths using Extreme Haulers. Is this from the launch or while running through the gears? Launching in 2nd works great with the Stars, its hard to keep the front down, and yet does not bog at all. If I had any more bit at launch it would be real hard to keep the front down with my stock 2000 swingarm.

2nd: While running Oldsmobile Hill I could rev out in third, and maintain 4th gear. In other words, in 4th gear it would maintain speed, but not gain any. In this case would it be better to gear up a little to get more out of 3rd, like going to a 16 front sprocket of gear down so it could pull 4th like a 14 front sprocket? For China Wall I could not pull 4th so I'm thinking making 3rd longer legged might be better.

3rd: Grab bars and bumpers. Do you run these in the sand? I'm looking at ways to save weight and will be cleaning up the frame and sub frame over the winter and these two items seem like an easy place to start.

Thanks for your time,
Scott

 

Mine is set up almost the same except I have a 46 Lectron, I used to run the sand stars until this summer and installed haulers.

They do bight better for hillclimbing, I had no problems climbing chokecherry or sand mountain.

I had to go down to 2nd to climb choke until I went down another tooth on the front, I now can do it in 3rd.

I changed sprockets not from getting beat but from a bent shift fork that needs replaced, now when I line up on my friends 450's I'm hangin right with em.

The only disadvantage in doing that is when out duning on the big bowls I run out of gears. With your swingarm being stock you still can take off in 2nd, but lean over the bars it will carry the front wheels.

Keep your bumper and grab bar, you will need these when you get stuck ,we've all done this at one time.

 

Scott, I would say a different set of rims may be a good choice for you if you want to hang on to the current tires. Going to a black lable rim would do you wonders in your revs. Also, look into doing a 520 conversion on your chain. Both those will shave the weight in the rotating mass area and do way more then the bumper or grab bar would for you. Plus like Seth advised they are nice to have when you burry it [img]i/expressions/face-icon-small-smile.gif[/img]

 

u-hum Seth huh????????????[img]i/expressions/face-icon-small-wink.gif[/img]

 

Yeah the DS is just too fricken heavy, save your stars for another toy, get some haulers 22" x 11 x 10" wider the rim the better I have 10" wide rims for floatation front are 8" wide rims, and the 8 paddle extremes hook up and teh quad floats now over the sand, Im running the 14 counter but im going to the 15/42 520 conversion soon, I have the same carb, and did have a endcap but went to a full exhaust, and that really helped it breath on china hill, and as dragon said, get a machinist to cut your front and rear hubs and get the aluminum rear sprocket hub also, gotta lighten that DS in the rear rotation mass to rev. then just add NOS China hill will never be hard to climb.....kidding. or am I????

 

Thanks everyone,
So, sounds like a 520 conversion, and machining the hubs and black label wheels will be in order for the winter. I already have the aluminum sprocket hub. Thanks to Mr. Meaner a set of front black labels are making way to Cobb. Now to find a set of rears.

What about gearing? Sounds like with the above the 15x42 is a good place to start with the 520.

And tires... so if I replace the 22x11x10 Sand Stars with 22x11x10 8 paddle haulers do I need to re-gear for the added bite? Is there any negatives to going with the haulers? With my mild engine could I get away with the regular haulers?

 

Im of the Bonus sized and I like the floatation, and the haulers are much lighter, but they seem to spin just enough the guys with bigger motors run 9 to 10 paddle so I think 8 is good, I learned a costly mistake I ran 20 11 10 and they just dug all the time, Fat holly say that 520 conversion is great! but he also threw on a 48 HV at the same time, try the tires Heck I wish I knew you were selling some 22" stars they were a pain in the fanny pac to find for another play quad of mine. Im still waiting on my 4" swing arm to arrive! so I can lighten the rear end!

 

Scott the answer to question (1) is the haulers will help you the most at take off but because they are lighter they will also help in the top end.(2)I am using 15-40 gearing with a 520 chain and 22-11-8 triple buffed tires and it works well for me.(3)Once i get my DS back from the builder which should be next week i will look at taking some weight off of it and my bumpers will be the first thing to go.In my opinion if you are going to get serious at all about the drag racing up the sand hill thing you should invest in a set of triple buffed 22" haulers on .125 wheels,they make a big difference.Even if you only used the triple buffed tires occasionally they make enough of a difference to justify the cost in my opinion.I would guess that a set of 8 or 9 paddle triple buffs would give you 2 quad lengths gain without changing anything else.Of course it is now time for the rebuttal to start.LOL.

 

22x11x8 hualers tripple buff and I would say 09 paddle with a four mm paddle thickness. there are only two problems with the tripple buffs first the price $345 and then the tires are thin and get flats very easy.
Heres the up side less mass = speed

 

ERBEDS650 I agree that the cost of the triple buffs is pretty high but gaining a solid two lengths on the hill for only $350 seems like a good investment to me.The triple buffed tires are very thin but i ran mine all summer for general duning and racing up the hill with no problems.It is good to point out that the triple buffs are not as tough as a regular hauler since everyone may not be aware of that.The triple buffs do benefit from their light weight but they also expand in height more than a regular hauler which helps with hook up.
