Feel like my 4lb jlf spring in my Hayabusa has lossened up

Installed a jlf 4lb spring in my Hayabusa joystick about 3 weeks ago and I feel like it’s already not as stiff as it was. Is it normal for a spring to loosen up after so short a period of time? Playing MvsC1 about maybe 5-6hours a week. I’m not super unhappy with it, but I’d like to know from the experts here if that sounds normal. Maybe I’ve just gotten used to it, but I would swear the stick shakes a little more now when I let it spring back to neutral than it did right after I installed it. Appreciate any feedback. Thx

Not sure how common for a 4 pound spring to feel different after that amount of time, but what I can tell you is that you can just take out the spring, stretch it a little bit to give it more resistance, and then put it back in. The feel should change to being a bit more stiff, and it should take quite some time before it loosens again.

Well, thx for the reply. So, i don’t wanna stretch it. Like i said, I’m not upset with how it feels now. I just wanna know if it’s uncommon for it to have done this. Am I being too rough? Is it a weak spring?

With a too stiff of a spring, you get this heavier bounce or deflection when you move the joystick lever to a direction and allow it to return to neutral on its own. The key here is not allowing the lever to go neutral completely by it self.

I feel a 2 lbs spring is the “sweet” spot, but your own mileage will vary.

I have an aluminum battop on it, so the 4lb is perfect… thx tho

So Weight + Crazy tight spring.

That will do it, that will cause the bouncing you see.

I really do appreciate your feedback, but you seem to be ignoring my initial post saying that it’s behavior has changed… as if the spring had lost tension over time. So it’s not about an initial flaw in the setup, it’s about the spring loosening over time. That’s what I was asking about.

That will happen with any spring, any spring. You got alot of weight with that aluminum bat top, combine that with frequent play and you eventually wear down the spring.

Yeah man. Can’t cheat physics. Those springs weren’t necessarily designed for those loads (i.e. big metal tops). If you slightly stretch the spring you’ll return it to its normal tension. It’s the prolonged compression (due to excessive load force) that’s made it feel loose over time. Stretching slightly won’t ruin the spring’s tension spec, as it will invariably revert back to spec anyway with a short amount of use.

If you dump the giant aluminum battop you would avoid both a loosening spring as well as the need for a four-pound spring.

“Four-pound spring”… my hand hurts just saying that…

Noticeably in just 3-4 weeks? I assumed over time, sure… this just seems fast.

Thx for the feedback man.

Again it depends on a number of factors, such as how frequent you play, the weight of the top, even the grade of steel used for the spring.

Glad to help, @Akkbar.

I guess somethings will just have to remain mysterious.

I use a 4lb spring, although without the aluminum top. I do think it’s gotten a bit looser over time.

The bounce/deflection thing is actually worse with a looser spring, in my experience.

A four-pound spring (with octogate for me) is great if you grew up playing on Happ controls. I play with my whole arm, not just my hand.

A bat style Happ competition wouldn’t suit you better? Or a least bat to on a jlf.

Well I do have a bat top (along with an oversized actuator, octogate, and 4lb spring) on my Hayabusa… I’m not really sure JLF would make that much difference. A Happ Competition (well I’d probably go with an IL Eurostick these days) would probably be good, but it won’t fit in Japanese-style panels, and the available options for American-style panels are kind of huge if you ever want to carry them around. It’s actually really hard to find a case that will even fit Happ parts in the first place and they are all bulky and expensive.

Instead I’ve got my heavily customized stick and Crown/Samducksa buttons, which kind of remind me of Happ Competition buttons, so it’s pretty close to an American-style setup in a Japanese-style panel.

The quality between the JLF and Hayabusa are quite different from what I hear. If you end up having issues with the Hayabusa you should give the JLF a try. Food for thought. Come to think of it my Mortal Kombat stick is kinda unwieldy lol. I’m a pretty big guy and I can’t think on taking that to a tournament if I wanted lol. My razer atrox has a jlf stock and comes with a ball and bat top, playing with the bat top is okay but I suppose it doesn’t have the same force as needed on the happ in the Mortal Kombat stick, but I’m sure the 4lb spring would make it feel closer.

Yeah, I don’t have much complaint about the Hayabusa… I think it’s actually pretty similar to the JLF (JLF parts mostly fit it), so if you’re swapping everything out anyway I think it ends up basically being the same.

Ultimately, I tried, but I just could not get into playing with a Japanese-style stick. I always end up pushing too hard and getting a diagonal when I want a cardinal direction. I was playing with a Myeongshin Fanta for a while, and I liked it, but I like this setup even better.
