Going back to 24/50 gears

[Turboflash]

From my experience, higher gear quicker drag racing
All in weight and helix setup
I’ll agree they work fine though
Just slower
I have 5 sets laying around

As always, depends on what a guy is going to do w sled - drag race or corner-to-corner or speed run, etc. With big tune & drag racing, w low gears (24/50) even with lots of long studs, just digs a big hole. Spinnin ain't winnin.

I do agree but I’m trail riding and putting a bigger lug not setting up for lake runs. I’m over top speeds but that’s just me. RockerDan posted basically same thing in another thread and I do agree with him tight twisty is fun with 24/50. IMO

Larger lug yes makes sense.
On 1.25 track I like taller corner to corner and all around. Never ran taller lug.
I currently run 1 inch hacksaw and will run this in everything I set up from now on. In N Wi and some up mi we are mostly hard pack and rarely loose snow.

it hooks and doesn’t spin much. Run 1.63 in 1 inch and 1.86 triggers in 1.25.
I’ll post my stuff in classified ads

Drag racing/radar runs..... is totally different then trail riding!!!
As a trail guy we don't stop after each corner line up and launch our sleds!!lol We ride at a consistent speed, we come into a corner slow down and hammer the throttle if permitted!!! With the 24/50 comparing to my 21/30 the 24/50 out performs hands down!!!!
24/50 in this application is way more of a rush then my 21/38..IMO

I think mostly we're all saying the same thing. If I mostly ran corner-to-corner I'd probably be 24/50 too. But I often ride on trails that are made for 998s, long straightaways, forestry roads that go for miles, huge lakes, etc where you can use big power and taller gears. Nice to glance down at speedo and see 125-130 and it's still pulling hard.

What was missing on 21 38?
Is it lazy you think?
I run 25 45 and rarely see over 140 on belt temp
3000 miles a belt

I am not arguing with you just interested in what you are seeing you find better
I assume it’s all loose snow riding
I don’t ride really in anything but hard pack trails.
I ran 24/50 in trail and thought opposite but that is my opinion
I am also a trail rider asking

Running last year with my tuned 998 on 100% groomed trails across northern Ontario with 24/50 felt allot more exciting! Coming out of a corner at 40-60km/h hammering the throttle and holding on for dear life then coming up to some small knolls and punching it putting the sled in the air would make me giggle in my helmet!!!
Don't get me wrong the 21/38 gear in this sled is still a blast but I just didn't find it as snappy unless I hammered down at higher speeds!!
115 -120 mph is plenty of speed for trail riding


It's all preference for myself having tested both high and low gearing I prefer 24/50 on our trail systems!!

You took the words right out of my mouth.

Were you been all winter Ernie? I heard you bought a 850 Doo, is that rumor or true?

TRUTH!!!

wanted to slower down this year apparently! Lol

Actual racing and what feels/works better on the trails is very different. The 22 top gear is slower in most trail conditions than stock gearing, and alot less fun. I will be switching to 24/50 gearing for next season as well to try it. 118mph or whatever it will top out at is plenty for me. I like the acceleration and wheelies.

 

[hellflyer]

Mine seemed to top out at 178km/h but only after the dalton sec spring .which is plenty for me seeing as I could only open it up once this year. Lakes never where smooth enough or had to much snow

What? Not what I've found on the Winder at all, and I typically I like to be geared down as I'm not a big top end guy and run more deep and loose snow. What are you running for primary weights and helix angles that you'd say that?

I started the season on the 21 to make life easier on the belt, and went back to the 22 when the 21 proved to be lacking the upper end speed I desired and it also made no difference in belt life. I also saw a decrease in acceleration in speeds up over 70-80 or so, and no increase thrust down low as I was hoping for, so for me, corner to corner down low was no better with the deeper gear whatsoever.

I can see where deeper gears would help on the TEAM clutches however if not fixing the slip down low they are so plagued with, and you know when they crack the primary sheaves they are not happy and making heat down low with slippage! That is when you band aid it with deeper gearing. A different setup however and it won't need a band aid with the deep gears. Maybe J & J can elaborate on that as he has found the TEAM needs a different profile weight to really rid that primary of the slippage.

All in what you like and what size trails you run!
I find that the 22/41 is faster all around for my set up and riding style when compared to the stock 21/41 gearing.

Stock gearing and Helix feels much faster on low end with it’s non smooth jittery response when compared to the smooth pull of the 22T. But it’s not. I also prefer the 35/39 which adds even more smoothness then the stock 35 and helps to keep the revs down with the Max Spool 16 tune.

Not many like that lazy clutch feeling on low end, but I do. Love the way this thing feels like a smooth underpowered sled on those really small slow trails. No herky jerky stuff here, but it really lights up quick with some throttle.

But yes if you are strictly corner to corner, it’s best to have a higher revving set up which takes less throttle to light up the engine when wanted! But out of the hole or cruising at speed and doing roll ons, the 21 is not as good with 270 hp or so.

I'd put 21/38s against 24/50s all day long on a 270 hp 998T on a 500 foot race to simulate trail riding.

On the teams I run 72afp STM weight with the stock primary spring

Engages at 4100 rpm
It is smooth and doesn’t act harsh there
I have no weight in heel
Tungsten and 1 in middle
Tungsten and 4 in tip
93 grams total and it revs good
I run stock helix and STM torsional with green in 4th hole

pefi 3r.
This would be a bit different depending on tune

The sled is faster from the ditch
The sled is faster from 20 punch
Faster from 50 mph roll
Faster from 80 mph roll
Faster everywhere
Not hard on belts and not building much heat

there are a lot of things you can do but this works for me
I run 1.8 ratio
I don’t run deep lug tracks and I have a ton of traction also
That makes most difference in setup it seems

I also like the rpm range dropped cruising up in the 80 to 100 mph range
We have a lot of railroad beds where we ride

btw
I believe the teams are junk
They perform well prior to cracking but will in time
Very thin near bushing that slides on bearing
