question for those who clutched their D-8's

[AKSNOWRIDER]

dang itmonte, I just sold mine on friday or I would be trying it..with that small of a helix i would think you could load the mid even more?..sounds like a promising setup..might also try what the pros come stock with..its a very snappy low engagement setup as well..very good setup for a factory stocker...

my 09 assault set up

slp single
Jaws can
Slp intake
pcv with slp map
19-41 gearing
68g mtx 2g tip,1g belly
slp blue pink primary
carles 62-42 helix with 3 delrins in secondary with stock spring
riding around 2000' with 8" light snow on hard base

when hitting the gas RPM's would spike to 8300-8350 then fall back off to 8150-8200 the rest of the pull, this was on flat land. If i were to run my helix on the 60-40 setting would this keep the rpm more constant? how thick of a washer do i need between the snap ring and roller cup to do this? Going to be riding at 7000'-9000' next week and was going to try 68g mtx no rivits and the helix on the 60-40 setting, think it should pull rpms with that set up? I also have a set of 65g mtx i gonna take along just in case i cant pull the 68's. I also getting the 2.5 camo this week so i hopping that will spin alot easier than the stock comp track and free up some more rpms.Thanks for any info.

ok, so i was out and did a few more passes today and here are the results, i got my camo 2.5 on finally(wow i love this thing), same set up as above but the snow was alittle more firm, 8300 rpm and 64mph track speed on a good half mile run, it took about 500' for the rpm to hit that 8300, i pulled of the side panel and the clutches were very warm, just so that i could touch them, so i marked the primary with a marker and did another 1/2 mile pass. there is still about 1" of marker left, WTF do i have to gear this sled even lower???? i am already at 19-41 do i have to try 19-42 or wont that be enough?? the sled does seem to pull hard but i am not a fan of all that heat on the clutches. Thanks for any sugestions and or info.

19/42 is the popular gearing setup. Not sure that it would make that drastic of a difference though. I would switch the weight location on your MTX arms. I think you would get less belt heat and better performance with 2g in the center and 1 in the tip.

 

[machinest660]

Thanks for the info monte, i going to west yellowstone next weeks so i going to run the mtx with no rivits but when i get home i will for sure try the 2g belly and 1 tip. Aksnorider also suggested i do that as well in some earlier posts. I think i will still try the 19-42 gearing to as i am sure it will not hurt and should/hopefully help eliminate some belt heat.

Carl's helix. which position?

2010 Dragon 800 155"
Got the Carl's helix/belly buster 62g wts.
Except for the PCV with the "Chad" map, completely stock.
Most of my riding is done around the 4-6500' mark.
Which position should I try first on the helix? 62-42-.40? Or 60-40-.40?
Thanks..

I believe 60-40/.40 is for stock exhaust and 62-42/.40 is for SLP exhaust.

Cool, thanks snowman. Never had a Team clutch apart before, hopefully it's not overly a pita to swap out?? Will try it on the 60-40-.40 side and see hoe she works!! Anyone have any experience with this setup on their Dragon? Improvement in throttle response/track speed/backshift etc?

43 tooth gearing with 32/42/36 helix dual cut with 60/40/36 and green/pink primary spring with 68gram and 65gram slp mtx weights and rivits whats some one thinkof this setup

 

[IDPOLARIS]

I need a few more RPM's need advise currently running.

SLP single with HPS can
3211115 Belt
19/42 gears
MTX 68G with 1gram in the belly
SLP Green/Pink 160/340
Black/Purple 160/240
2 Derlin washers
62/42/40 or 60/40/40

Really both angle's pulled really good and back shift was great just want to get up 8400 to 8450 rpm's and see how it runs.

I was riding anywhere from 6500 to 8000 ft today.

 

[AKSNOWRIDER]

put the 40 in, how old are the springs? if not pretty fresh, replace them, that should get you a 100 or two..........

 

[IDPOLARIS]

Thanks AKSNOWRIDER


I run the 42 in and the 40 coming out. As far as the springs go the green/pink is brand new just installed last night now for the Black/purple that was installed early in the spring. If i was to pull all the weight out would that help I will pickup a new secondary spring this week from slp and get it installed also.

I did for forget to take a sharpie and mark my clutches to see if i was getting clutches to full open and full closed looking at the drive clutch i dont think it was closing all the way as i can still see my scrub marks from cleaning it.

 

[AKSNOWRIDER]

if they are that new..most likely not, take your weights to a gram scale, remove 1-2 grams each off the back side of ea. (have to make equal removal on both), that should get you rpm, and give you back some adjustment,

Well the green/pink is brand new and I will get a new Black/purple for secondary and get it installed this week.

It could be my Belt a little bit to i have over 1100 Miles on it i will that today as far as grinding the weights I will leave that to someome else.

Also I don't think the primary clutch was closing all the way to get the belt up to the top is this caused by to light of weights.

Thanks AK for all your help and input.

 

[diamonddave]

Bill you might be a little too heavy with your weights. I was running 65 gram weights with a 140/330 (the stock Polaris primary spring) at 3,000-6,000 ft and turning 8,250-8,300 RPM's with a fix kit, SLP pipe, and 08 head and the Carls helix you are running.

Were these Polaris 10-66's lightened to 65 grams, or some other weight?

 

[IDPOLARIS]

Thanks Dave i really hate this clutch tuning i want to load the motor but want certain rpms . I know when i was changing the helix from 42 to 40 the clutches was Hotter the H*LL wow. I run the 40 back to the trailer and they were still pretty darn warm. I am still sure that my primary is not closing all the way to bring the belt to the top.

 

[diamonddave]

66 bellybusters with approximately a gram ground out of them. They each weighed 65.1 gram on my coke dealer digital scale.

 

[diamonddave]

I would also highly recommend tuning with a new belt...

 

[IDPOLARIS]

OUCH i will be picking one up tommrow but your right mine has alot of miles and i have smelled it burn a time or 2 Thanks for your help and i will keep you posted.
