Primary clutch spring

[powderpilot]

Does anyone know where I can get a 180/310 primary clutch spring?

To fit what? Go to Dalton Industries web site. They have all the applications listed for sleds and quads.

The best I can find is a Team 180/320. Should work fine you just may have to use a little heavier weight.

Yeah, that's what I have in now, it's engaging a bit high. I ordered the 310, but got the 320 instead.

Can anyone tell me what the numbers mean? I'm guessing it's a spring measurement in MM, 180 being the circumfrence, and 310 would be the length of the spring??? If that's the case, then there's not much difference in length between the two, but I'd like to shave off 100-200 RPMs off the bottom. I'm not over-reving on the top. I'm running 79.5 g weights.

Thanks for the help.

If you want to lower the enguagement you need to lower the initial enguagement, like a 160-320=or 160-310== that will lower your enguagement

Powderpilot, the first number is the force of the spring at installed length, and by that I mean what the manufacturer claims the installed height to be, not necessarily the cat's, doo's, polaris's, or yamaha's installed height. A lower number will provide lower engagement if installed heights are the same between two springs.
The second number is the force applied by the spring at compressed height (see above) and will affect your operating RPM A higher number (tension) spring will be "revvier", but may not allow the clutches to shift out fully (not loading the engine).
What you need to do is find a Team spring (if that is what you're using) with the same finish rate, but a weaker (lower) initial rate. Hope this helps.

Ah, that makes sense, thanks! So how do I know if heights are the same? I think my spring was meant for a Dragon and it seemed longer than the one I swapped out. I'm running the Team spring and it's pink.

Your new spring will be taller because it has not been fatigued and compressed a bunch of times. If it is only slightly taller then not a big deal as they typically are. you need a 170 or 160 initial rate to lower the engagement RPM. The springs all look a little different as the wire diameter, number of wraps and uninstalled height, all combine to give the different initial/finish rates. How is your tension on the secondary? You say you are not over reving but are you shifting out fully on your primary?
