That seems really low for the full shift force. I found a chart that shows exactly what you've listed here. Says preload is 35 kg and total force is 101 kg. Interestingly, (although probably not what you should do) if you add 101 and 35 to get 136 kg and convert that to lbs, it comes to 299 lbs. Which would be about the same as what I was running.
What does the spring rate mean and how does it play into the overall rating of the spring?
It's been a hot minute since I've post on here. I think I'm close, but can't seem to get the last bit of it figured out. RPM's are holding nicely now. There's no dropoff and it hits RPM target almost immediately. I'm not able to make any speed though. Pulls really hard till about 60mph and then slowly climbs to ~85+mph. It's still climbing, but slowly. My Skidoo 850 gets to 100 mph in about 2/3 of the distance. My friends stock SRX is faster than my 850 so I can't imaging there's that much difference between a stock SRX and my piped and modded SX.
I guess it's possible, but I have read all over the internet of people doing this conversion (on other Arctic Cat's) and getting great results. The primary was paired with this secondary for this sled. I know it used to work. I used to race it with this setup. It would blow Thundercats out of the water. BUT, that was years ago and the sled has been messed with by others since then. I'm trying to reverse engineer what they did.
If I changed springs, wouldn't that potentially cause slippage? I'm not sure how much leeway there is when it comes to the secondary spring.
Hmm, okay. I do have the ability to move the yellow spring one more hole. I guess I need to look up the spring rates of the yellow and blue springs.
If I'm not mistaken, each spring has a range of pressure, yes? If so, then the notches in the clutch is setting where in that range the spring is set? If that's the case, then having the yellow and blue spring each set at the same/similar force, how would each spring rate change as the clutch opens?
Sorry for all the questions. What would be the possible up side to running the blue vs the yellow? Possible down side? Is there a HP rating in which each spring is recommended? Or perhaps the better question would be, what HP are you running with the blue spring?
Hmm, okay. One thing I did fail to mention earlier was that when I did my runs, I wasn't making peak RPM. I forgot to bring my primary tools and parts with me to make that adjustment. I was only getting about 8,600 and I want to tarket 9,000. So do you think I should stick with my spring setting for now and see how it performs?
I'm running a straight 51 helix. I was running a 49 before but changed it when I wasn't getting the acceleration I wanted. That was before the spring change though.
