for doing a 2000 foot speed run I would be geared as tall as you can, get rid of the roller clutch and put in a red polaris spring and a r-7 or straight 34 or 36 helix. and as much weight as you can pull,
nothing goes like 3 holes!!

WOW Great Info guys!!
As mentioned I have 1996 Storm and was wondering if power band or thoughts on sweet spot. What I have read is 8000 I currently run 10-62 and still pull 8400
Seems like it pulls hard then lays back a bit at 80-90 mph 8400 rpm..
I am all stock pipes porting ect..
Thanks
Try 10-64's or 10-64M's. That's what I had in mine last year with the stock pipes and porting, it pulled good at 8000rpm.

I got a chance to try the 21/39's ,pulls real hard, a lot more responce at lower speeds but didn't have the room to run out the top end, only up to 70mph or so. At wot the rpm will hit 9400, will have to change weights, maybee 10-62 or should jump to the 10-64's ?

What were you running for RPM's before the gear change?

Rpm befor the gear change was higher, 96-9700. It was above freezing wednesday when I ran it, may be the reason for the lower rpm.

Do any of you Storm guys have a good crank? I just snapped the pto stub off tonight. I came out of a corner and stabbed the throttle and BOOM. I rolled to a stop and opened the hood and there it was. The primary was laying in the bottom of the belly pan with part of the crank still in it. I need this sled back together by the end of this week!

Yellowstorm800 really sorry to hear your misfournte! This is the first I have heard of this on a Storm crank!
I have a quick question for the group:
My 1996 storm is now running 10-64 and still pulls 8200-8300 and runs very hard up to 80-90 and then is slow to get up from there? speedo has only been up to 100-110? I have stock spring in the secondary 2nd hole EPI Spring..
How far of a run to get top speed? Going to radar run next weekend.. I have stock gearing now will try that this weekend also have heard runs above 120 on speedo. maybe loosing traction I have 168 picks 1.00 in stock track.

With the money you have invested in the rest of your motor, do you really trust just putting in a used crank?

I found one this weekend. I didn't buy it yet because we are going to split the cases tonight and make sure it is good. I am still putting new outer bearings on and new crank seals. I just want to make sure that the centers are good.
Bgbytor800 - Depending on how long the radar run is you should probably just run stock gearing. It also sounds like your secondary is to tight. Maybe try a running a softer spring.

Sorry guys. I haven't checked this in a few days. I will be getting the Storm back up and running again tomarrow. I worked on it all night tonight and all I have to do is get the pipes back on. When I put the motor back together this time I decided to run just a single head gasket. I haven't checked the compression yet but it sure seems to pull over alot harder now. We'll find out this weekend how it runs out on the lake.

yellowstorm, when you have a chance I would like to know what you end up with for compression psi with the single gaskets, I picked up a single set but have not swapped them in yet.

I would probably sell my HPE spring but I will have to find it first. I have a brand new one and a slightly used one. I will look tonight for them. The engagement on my Storm with that spring was very high. It was around 6,500 rpm.
I haven't checked the compression yet but I know it has a little more power now. I was running 10-56 weights before turning 8700 rpm and now I am running the same rpm with 10-58's. I am deffinitely going to gear the sled up though. The sled tops out at 107mph and then it starts over revving to 9,000 to 9,200rpm. I think I will try stock gearing and with either the 58's or 60's.
