Proline Kit Update

I've been riding sleds for close to 30 years. I feel my butt dyno can at least tell if a kit pulls harder. I might not be able to give you exact elapsed time gains but I can tell the proline pulls harder.
 
We just finished a big 5 day ride up in the UP, and eveyone that rode my GT was amazed at how much it stretched their arms - "this thing pulls like a train" was the most common response. I made a couple small change to the clutching, loosening up the secondary a bit, and everyone rode it again, and responded that it felt like it slowed down, doesnt' pull nearly as hard, and alot less snappy. Funny thing was though, when i ran against a Doo Renegade that was in the group, it picked up 3-4 lengths from where it was previous, and it felt slower!

Moral of the story... the butt dyno doesn't mean a whole lot, just because an egine is snappy and has alot of throttle response, doesn't mean it is pulling hard or running faster. I'm not saying the proline kit is faster or ins't, i don't even have one, but i will say your seat of the pants is pretty easy to fool.
 
SRXracer is right, you can not go by seat of the pants, it will fool you every time. Sometimes it feels fast but is in fact going slower.
 
Thank you Reaper and SRXracer!!

Yes, thank you for proving nothing. Just because ONE sled got quicker yet seemed slower by loosening the secondary does not mean that my sled got slower by installing a proven clutch kit that includes weights, both springs and a helix. A kit that a good portion of the riders are reporting significant gains. The kit also put the sled dead on in the power band where the stock set up was 1000 rpm off. Maybe my butt dyno is not 100% accurate, but chances are, looking at all the information the sled is running better. I will do some comparison for sure but I feel very confident I have not lost ground with the Pro-Line kit.
 
alright, lets keep it calm, I can shed some light on this.

The Butt Dyno can and often times does have a placebo effect.

On car and motorcycle forums that are bigger than this one, it has gotten where Butt Dyno info is disregarded completely. Why? Because it is proven to be inaccurate in so many cases. Some modifications that guys have raved about, actually made cars SLOWER believe it or not.

So bottom line is guys who may have hung out on other forums, tend to disregard butt dyno info. Does that mean the info here is no good?
No but it should be somewhat taken with a grain of salt, that is all.

A few weeks ago MrSled in his infinate wisdom suggested a "clutch kit shoot out"
Controlled tests same sled, same conditions. That info is about the only info that is conclusive proof. Ulmer and Simons were all for it, but others did not seem to be interested.
I will make a prediction if a shootout does happen, and that is all the kits will be fairly close in performance.

Cluthing is a black art, I will leave it at that !
 
All of this clutching information is great, but without running agianst some sort of baseline (like a stock apex, or at least another sled that doesn't have any changes made to it) before and after any changes are made to the test sled, the results are circumstantial at best. I'm certainly not calling anyone a liar, but all of these results would mean alot more to everyone if there was some sort of baseline to compare too.

At this point i certainly feel like i have picked up some with my ulmer kit too, but i am also curious to throw the stock stuff back in now that i have 1000 miles on it and see how much difference there really is - ALL WE NEED IS SOME STINKIN SNOW!
 
Anybody no what happened to that clutch shootout? - is it still going to happen? - MrSled?
 
I dont think it will happen unless this weather changes and we actually start winter.
 
Go Big or go Home.

To bad you guys are not in MusKoka. there is a #*$&@ load of snow here although it rains one day snows next. Lake Of Bays right now is slow.I rec my Proline kit yesterday.Waaaaaaaay late. I wanted to test it before heading into Quebec. When I get back . I will report. travelling with 3 other stock..GT's and 1 RT. Iam taking .8 Aluminum rivets and 2.3 steel with me. My Kit did not include either. I did notice considerable gain by changing secondary spring and shaving the helix. That put the sled into overdrive. You also have to be ontop of the deflextion, and offset... my offset was way out..Guys I just want to be the first one at the end of the lake.660 to 1000feet does nothing for me. if you lived here in the land of big iron you would know what I mean. Ps. THERE IS NO REPLACEMENT FOR DISPLACEMENT. Dam I'am banging my head on the wall.

Good post +1
 
If nothing else, I will test all kits anyone wants to throw at me this asphalt season. Same driver, sled, track.
 
Don't you have to clutch differently for asphalt opposed to snow? - never raced asphalt - might try it - with the winter we're having, might be the only miles I put on my sled this year! LOL
 
Thanks 87gt nos . fore bringing me up to speed on Spence bashing me. I f you read my post you can tell I did not publically bash him like he did to me.I knew quite well it was beyond his control on delivery. What I did want was the kit and the gear here so I could do some testing before I depart today for Quebec. This guy has to grow up .He must also think we are all naive .posing as Slightly Stock. Go Figure You owe me an apology Spenc. Bill
