That sounds great. Me and some buddy's are looking forward to it. We would be bringing an Edge sled with a XCR 800 motor and possibly a Pro-x with an XCR 800 motor. Then of course my Storm. Just keep us informed about when and where. I would like to run against your Storm!

Yeah, we could have our own piped/ported Storm vs. stock storm race?? There should be tons of sleds to line up with anyway.

Just want to say a excellent posting of good info
I recently became the owner of a 1996 Storm 800 and was it looks to be 100% stock jets needle setting clutch etc
what would be the first three things you would suggest doing to improve a already great sled...
The only thing I have noticed is some slight bog at 1/4 to 1/2 throttle then it clears
Cleaned carbs new plugs seems to start really easy and some smoke after a couple jabs of the throttle?
Any guidence would be much appricated
Thanks

I would start with 21/39 gearing, then get your clutch engagement to about 4800-5000 rpm. Add some v-force or boysen reeds and that should clear up the bottom end.

I agree, another great add on would be a new track. 1.25 Ripsaw or a 1.35 Cobra track will make a huge diff. Just stay with the stock jetting.
Yellowstorm800, are you going to be there on the 9th,10th,11th weekend?

So BattleStorm I was told to take the stock jets 400 400 420 down a notch? You are saying to stay with Stock?
was looking at going 390 390 410? I know that storms can blow or sieze at midrange
Yellowstorm800 getting the engagment up is by a change in spring in the primary correct? It currently has
10-60 weights and Blue spring in primary, Also changing the gearing does this require both gears or just the top?
Thanks to the both of you and Hail the mighty storms!

Battlestorm, I don't think I am going to make it but its still a possibility. I finally got it fired up last night.
When changing the gearing you are going to have to change both top and bottom. Just change the primary spring to raise the engagement.

Yellowstorm800: Not sure if your going to have the sled set up in time?
bgbytor800: put in 62 gram weights, you want that sled to run at 8,000 rpm. The blue Polaris primary spring is a good spring for Storms. I wouldn't focus to hard on getting the engagement rpm up, its hard on belts and engine mounts/straps and really unless you have allot of traction you will just spin more.

Quote Yellowstorm800: Not sure if your going to have the sled set up in time? No, the sled will be done this week. I just don't know if I can make it up that weekend. I might be able to make it up there for one night. We'll see what happens, I would really like to get up there and put my sled up against another strong Storm!

bgbytor800: I'm not sure about the jetting your Storm? My Storm runs 400,410,430 but I have diff cylinders and a hotter CDI? You can get buy with lean jetting depending on how long you hold it wide open for. Your really jetting for distance when you jet a sled. My XCR comes stock with 440s, I run 410s on the trail. Last year for a 1,000ft radar run I put in 350s and gained maybe 1mph, then put in 110 race gas and lost 2mph.
Yellowstorm800: Well try your best to make it, there should be 2 other strong running Storms there as well. I think the fast Storms are going to beating the slower XCR's which should be fun.

The early 94 CDI, Polaris does not sell that CDI anymore, a new part# supersedes the old one. Typical first year sled stuff, the first year a new engine or sled comes out they make the CDI hotter, then next year they put in a slower one. All the manufactures do it. Some examples that I know of, early 93 Storm, 93 T-Cat, 93 Mach Z, 97 XC 700 and 700 RMK, O3 F7, 99 XCR 800 I'm sure there’s allot more to add.

Battlestorm, Yellowstorm
With the recommendation of track change are you running Pics? Also Have 4400 miles on stock motor and plan on rebuilding this summer.. Do you have any recommendations? Crank, cyl,heads, Pipes? Also want to keep it a rocket but reliable
I love my 1996 so far not sure why they get such a bashing?
Engagement is around 4400 and will change weights to get max RPM down from the 8500 to the 8000 with 10-62
Jetting I am running stock CDI with 390 390 410
seems to have a slight hesitation (Small) around 1/4 to 3/8 throttle
You guys have been great and glad to find guys that enjoy the storms as I do. What area are you from?

I'm not aware of any POO 800, new or old, that can get out of the hole without studs. Even my stock edge 800 with 136" track will spin on hard throttle at almost any speed without pics...
Also, I've heard that Vforce3 reeds will kill the low end bog on the storms. I can't say for sure, since my storm already had them installed when I got it, and it had no low end bog.
For parts recommendations, it all depends on your goal.. A reliable trail sled means don't do much except replace what's worn or ineffective from the factory. A Mod sled that's fast, expensive and you plan on constantly turning wrenches on, do it all.
95 - Storm 800 - Modded - AKA: FrankenStorm - Totalled near 100mph at Tug Hill!
96 - XLT/SP with Storm 800 trip/trip and now EFI - FrankenStorm II lives...
95 - RXL -- Sale Pending --
05 - Edge 800 long track - Stayin' stock for now..
---------------------------------------------
It made me more compassionate, more empathetic, more nurturing...
I FEEL LIKE I'M TRAPPED IN MY OWN WORST NIGHTMARE!!!

If the compression is good just leave it, no need for a rebuild, these engines will go along time. Mill the heads .020 and put reeds in it. Stay with the stock pipes. See what helix and secondary spring you have, 8,500 rpm seems high for having 60g weights. 62g weights won't bring the rpm down 500 alone unless your tach is just off allot? A Ripsaw or Cobra track does not need studs unless you are racing on ice.
Good luck.

I just checked the quench clearance on my storm, .092 I think this explains the low compression numbers. I guess with the double head gaskets , weisco pistons and aftermarket rods the tolerances start to stack up. I am used to working on v-8 stuff .038-.040 minimum deck clearance, does this hold out on the 2 strokes?

Battlestorm and I run different set-ups for traction. He runs a 136" non studded track and I run a 121" X 1" track with 192 studs. It's all in personal opinion. As for the hesitation, try Boysen of V-force if you haven't yet. Also maybe try a almond/red primary spring.
As far as the motor goes, if it runs good just get the right set-up now and it will be a fast reliable trail sled. Get your gearing and clutches dialed in. But if you have to dig into the motor this summer I would suggest getting some porting done. My motor is ported and the heads are machined. I am also runnning PSI pipes and bored carbs to 39.5mm. I don't know what Battlestorm all has done to his but we haven't had the chance to put them up against each other yet. The time will come Battlestorm!

PAStorm: When I milled the heads on my Storm some 8+years ago I did check the squish and it was at minimum for a 2-stroke. I don't remember what that was though?? I do know they need more squish then a V8 because the looser bearings in a 2-stroke. What I would do is take apart your double head gaskets and make them singles then use the Copper spray made for head gaskets and coat them up good and torque them down. That should raise your compression 5-10 psi?

Battlestorm: I won't be able to make it to Hayward this weekend even though I want to very badly. I'm sure there will be another one just by looking at the voting. I will be racing my buddies Edge with the XCR 800 motor this weekend. He has HTG pipes otherwise its stock. What do you think will happen? I think he will probably beat me off the line but i'll go by him in the mid range and just keep pullin on the long run.

Yeah, that would seem about right, if both sleds are set up the same with equal traction. The wedge and the gen II are the best Polaris drag chassi ever and will always beat an equal powered edge. Also those HTG pipes on his stock engine could easily be hurting him as well?? The shootout will determine that…..

Ok guys
So changing the gearing will give me a better hole shot?
Changing to a 10-62 weight will hopefully put me closer to the 8000 rpm threshold where the 96 storm seems to make the most power?
Stock pipes are good.
Stock secondary spring good?
Helix? Stock?
Stock 96 CDI

Yep, the gearing will give you a better hole shot and not loose any topend speed on snow. Run 62 gram wieghts. Stock pipes are good. The Polaris silver/blue secondary spring is a good spring to use. The stock helix will work good but if you stud the heck out of it you can run a full progressive helix and get even a better hole shot and better midrange pull. The stock 96 CDI is reliable and works.

Silver/Blue is stock i think!
Would a "Full Progressive" helix be a Polaris part? Or aftermarket like AAEN? is that like 34 to 40 example # but is that what progesssive means?
Still trying to decide on Studs or Camoplast Cobra 1.50

It might be the stock spring? Not sure... Polaris does not make a full progressive helix. A Polaris Helix like an R12 is a 50/36 and the angles on the ramps go like this: 50 50 50 then progress to 36 36 36 36. A full progressive helix would go 50 48 46 44 42.... all the way down to 36 degrees. With a FP helix the secondary clutch will shift out faster then a stock helix.
If your driving on packed snow, looser snow or powder the Cobra can't be beat. If you drive on really hard packed snow or ice the studded track will have an advantage.

Battlestorm /Yellowstrom
Just curious have you both changed your stock reeds ?And if so are you using boysen or Vforce 3
Went to install Vforce 3 and relized you have to modify the carb boot by cutting the rubber at the rear of the carb boot as it fits into the stck reed cage.
Wondering if I should go Boysen?
Thanks
