A month or so ago, i ordered some new paddles from RMATV, this is there new 22x11x8 hauler tire.

It is on a Lawnpro carcass, and is pretty light, but the profile is very flat and wide. Take a look at these and tell me what you think.

The rollout says 70 on the tire, i havent measured them yet.

My problem is, even with 12/38 Gearing, these paddles with 5lbs of air, preload on shock all the way up, or rings all the way down, and my 140 lbs on the tank, it will NOT launch in second. Just bogs and goes. This is in pretty heavy Oregon sand.

The tires are on 8x8 rims, do you guys think i would benefit from putting these on an 8x6 or 8x7 rim?

I want them a little bit rounder, but i want to be able to launch in second so i can dune this bike. 15/38 gearing is worthless for the duning i do.

I do not have the clutch mod, does anyone think this would help?

When i launch, i tap it and dump the clutch, should i be trying the feather technique out of the hole?





Thanks!

Here is a vid with these paddles, 5 lbs of air, first gear start with 14/38

Thanks guys!

I would say your over paddled.... I know its diffrent sand and all... but 8 paddles is a lot down here in Cali... and if the sand is a little wet... forget it....


I know in wet sand I have run about 7 lbs of air on my 5/5's


I would run either 7 paddle or 6

nah for oregon sand you are perfect. I run 8 paddle extremes and launch in second with a feather on the launch, works perfect for me and i am about 200 with gear. what all is done to your bike? being able to launch in second makes a hugeee difference on tree shots and drag racing. Im also running 14/38 btw so my 5th tops out realll fast.

I wouldn't run 8 paddles either, but again, we're talking CA sand vs OR sand - not the same.

I can tell you last season I had an extra set of 22x11x8 7-paddle std buff haulers and they were 70" R/0 mounted on 8x8's and were identical in R/O to my 21x12x8 6-paddle extremes mounted on 8x7's marked as +68" R/O. I replaced the 8x8 rims on my 22's with 8x7 and gained 2 more inches of rollout, and they were noticibly taller than the 21's after the rim swap.

I still don't think that a rim swap is going to get you 2nd gear starts the way you want them - you would need less paddle/traction to do that.

I'd try a 39 or 40 rear sprocket first... I can't believe that with your lil ass (140lb) that it won't launch 2nd though...

I dont know why i cant launch in second either.

Im gonna try some seven paddles, and some other 8 paddle haulers.

The bike is 57.5/34/5 stockbore/stroke bike. It has a lot of power.

Do you guys think rounding the tire carcass out will let me launch a little better?

Thanks alot for the input!

-Kip

I personally don't think that going to a smaller rim will help... Here is why, it will make your tire taller / which will make your gearing taller.

i agree with being over paddled. the sand in the vid you posted looks wet. a 7 paddle might be your ticket, gearing i would try 13/40 for a harder second gear launch.

Ok cool. Thanks a lot guys!

My buddy has some seven paddles that im gonna try. They are a lot narrower tire though. Same rollout 7 paddle haulers.

-Kip

Hey buddy, after about three days of good weather to dry out the sand you are going to spin those 7 paddles right of youre bike. One thing we have done before kip is pressure up to about 12 lbs and set those bad boys in the sun for a day and you could gain 1-2 inches of roll out if thats what you are wanting, but giving yourself more roll out is only going to get you more traction. My proffessional advice would be go to a 18 inch 6 paddle gecko tire and then you and I can line them up again . Run those 8 paddles at about 7 lbs feather the cluch and bounce off the RL on the launch and you will be fine, The sand is about to get real good here in a week or two. LATER BUDDY.

i think that going to a narrower wheel, you are going to get the tire to bulge more and increase the rollout. that will also increase the spacing between paddles. this may help you launch 2nd better.

i am on the same page with rebel. those geckos are the $h!t

I will try that leaving in the sun thing!

Anyone else going down next weekend??

Ill bring along a set of geckos and try 4th gear launches!

-Kip

florence i should be there along with my new hoe ; )

Bring me one.......

Anyone think the clutch mod will make a difference?

-Kip

^^^^ wouldn't hurt

i would do it for sure fasterthanQS. i have a ton of stock fibers if you want one ill give you a good one to throw in.

i just bought a tusk crf kit that im going to try with the HD springs

doing the clutch mod couldnt hurt, but i dont think it will make the difference. i know we discussed feathering the clutch in another post. i think better gearing is the answer for you. i can do 2nd gear launches all day long, but i am running 20's with 13/40 gearing. that gives me a ratio of 3.076. with your 22's, you would need to go to something like 13/44, for a ratio of 3.384.

since i'm running 20's, clearly i'm not a drag racer. you may not need/want to gear down as low, but the ratios you mentioned seem aweful high to me to be running 22's

A better clutch would actually hurt you, a little slip would allow you to leave in a higher gear. It's just the nature of the beast with the wet heavy sand... I think the main difference is the lack of fines in our sand which makes it harder to get up on... which is why when its dry we need more paddles. When its wet though the sand will bind up and you could get by with less... BUT that is only for drag racing, get in a deep hole and being under paddled could mean not getting out... Its all about compromises.

Kip I don't have anywhere near the power you do and have little issues launching in 2nd at 220 with 21 12 8 8 paddle haulers with 3.5lbs of air... Practice with the clutch a bit and you'll figure out how to launch in all sand conditions.

Good Luck.

I have always been able to launch great, and can launch all my buddies bikes harder than they can. The 06+ bikes launch way easier than mine does.

Ill play with it, maybe it was just the sand.

-Kip

Ya kip I just got back from florence and the sand is still real heavy but with the sun and wind today it was looking alittle better when I left. Give it a couple of weeks and the sand should be in great shape. I dropped to 13/38 and was so close to second gear launches but not yet. LATER D.J.
