some go fast trail set up's for stock 800 ho's

Brock said:
That secondary spring may be hurting your upshift(slow,to much tension). It's good for back shift.
Both Cutler weights are good. Depends on what you wanna do?

Regular trail riding choose the IT's

Fast trail,some racing and aggressive choose the turbo mags.

Look at clutch alignment, get belt to sheave 0.015", I like 0.120" float (0.060" in from tool, 0.060" out from tool)

A good start would be Cutler weights, IT's start with 68 grams, TM's,start with 64-66 grams,120/310 spring

48/44 helix (other angle is 46/42)
140/220 spring

That might work for you

As for the 2017 800 ho motor for rpm.it was 8400 rpm for peak HP on dyno testing when not fully broken in.

thank you very muchm very good info

Putting in heavier weights will not lower your engagement. Something is wrong

are you sure ?

Heavier weight will makes the clutch to shift faster ?
then If it shift faster, it will engage earlier ??
am i wrong ?

clutch engagement is based on centrifugal force so more base mass will lower engagement. go with the TM cutlers,as brock said that spring in the secondary is way to strong..
 
you want back shift ...buy a tied secondary 66-62 and 64-60, closes as you can get to a 48-44,46-42 in a tss-04..run stock spring..

Yes, it was early when I posted that. No coffee yet. Duh!!
 
Hi guys
this is an up date with all the good information.
sea level 0-400 ft max
stock gearing 22-37, 2.52 9T drive sprocket

standard set up as in the Manual is
10-66
100/275 primary spring
160/240 72 secondary spring (spec in manual)
helix: 58-44-36

My actual set up

10-68
100/275 primary spring stock
Blue/Black 123 203 73 stock mine comes with this spring ???
helix: 58-44-36 engagement actual 3100 not 2400 rpm ,my mistake
rpm on top : 8200

I'm not too sure about yhe Team , Tied. I bought one las years to put on My AC F1100Turbo ( flash to 270 hp)
too gain some back shift, and my originale AC modfied was way better than the team for back shift .
Maybe on a 2 stroke its a different story *

Your set up now is better then what you had before because you had to light of weights and to heavy of a secondary spring.
These motors like to be loaded with weight ( up shifts quicker and heats pipe)

The 17's in break in mode like to rev to 8400 rpm for Max HP. Out if break in mode is the same. Jaws had haulins in dyno out of break in mode and was the same (8400 Max HP)

Get your rpm up a little from 8200 to 8400. This can be done with a primary spring change only with your current set up . A Polaris 110/290, 120/300 springs should get you there .(8400).

Now I do wanna say these won't work for everyone and I'm just trying to help.

Stock 15 or 16 800 ho

Elevation=800-1200' asl

track tension and chain tension set a little looser then polaris spec's

tps set to spec

clutches aligned properly

belt to sheave set at 0.015'

studded track

rider sag in is 4 inches from floor up to bolt of k brace

clutches and belt cleaned

180-220 lbs rider

primary clutch is within spec




1.73 gear ratio

Primary-120/300 with 10-70 gram weights

secondary- 66/44.46, 140/220 spring or a 50/44 full progressive with same spring.

Both clutches are the same temperature(which is good). These set up's work really well for fast trail. Slams in at 7800 and climbs to 8200 rpm were it should be stock.

The TPS should not be over 4.320 at wot ? Mine was at 4.550 and 0.908 at idle, dealer said if he lowered wot setting than I would be out of spec at idle. Is this correct? Clutch alignment was off. I re-geared have not done clutch or secondary changes yet. Wondering about TPS and have questions about PC map and Bikeman Pipe. Does DTI map correct HP loss over stock pipe in 7200 to 7800 area. Thought you guys had good numbers with Bikeman pipe when you Dyno-ed pipes last year. Why I bought one. Now I'm reading stock pipe pulls more mid HP, where corner to corner trail riding occurs? 15 rush pro S new last March got about 1000 miles on it wanna get more out of it.

thank you very much Brock to guide me in the right way :)

I try something this morning, not the ideal set up but best compromise with part i can find around.
it was just a est to see what influance a few psi rating can have on the sled.

So i try a 122/285 primary spring , with my 10-68 weight,
target see was how many rpm will i gain on engagement 122 vs 100 stock
and how much rpm will i gain on my finish 285 vs 275. Last wich influence
this higher rating springs will have on my shifting.

RPM wise i'm right where i was thinking i will be
Engagement pass from 3100 to 3300 20lbs more = 200rpm
finish +50/100rpm 8250/8300 from 8200 +10lbs=100 rpm

So like i said it was the only spring available here too soft on the finish to achieve my target 8400 rpm
but i have a 165/310 on order plus Cutler IT weight on order, that must do what i whant

My target is to put 10-70, with 165/310 wich i think will give me around 3700 rpm engagement and 8400 on finish
whit more load with the weight.

I chose Cutler IT vs TM , after talking to a tech support at cutler, he recommand it over tm .
He said for agressive trail riding when you want a good back shift the IT is Superior to TM.
He also tell me that even if they said they have a similar profile as a 10 series, they still are more
agressive than Polaris weight.

My observation, whit the new spring this morning, the sled is a lot more lively, better response not as slugish
as the original.

You will not be disappointed with the bikeman pipe. I would pu the on trial performance of the bikeman pipe and the pipemod about the same, but they are both noticeably stronger than the stock pipe.

What base weight Cutler IT weights did they recommend ?
