Shifter spring to tighten pedal/lever?

corksil · January 29th, 2015, 11:06 PM

Where did I see a magic little "as seen on TV" type of product that claimed to be a tiny spring that replaced an OEM spring in the shifter mechanism which tightened up the shifter play?

I saw it on a website in the past few days but can't find it again...

Does this ring a bell for anyone? Does anyone know what I'm talking about?

It was a spring (about an inch long) that claimed to drastically reduce the sloppiness of the OEM shift lever..

(FWIW I'm aware that a loose drive chain will cause a sloppy shift lever feel, and that's not the issue I'm trying to resolve.)

Thanks!

Dang, lots of internet browsing history searching.... I found what I was looking for.

Does anyone have any experience with this spring? It's effects on shifter feel?

step 1: remove shifter star spring cover bolt from the top of the engine case
step 2: place two washers in hole and replace the bolt
step 3: profit?

I got one.

It is stiffer, I have no mis shifts ever.

But If I don't shift hard enough it doesn't complete the shift.

Now that sounds good to me

Thinking about this, its not exactly the same effect. What your talking about is preloading the shifter spring, while the replacement spring is a higher rate (assuming) unit.

Assuming you press the shift lever with the same force, on a higher rate spring equipped shifter you get less movement at a linear rate, on a preloaded spring you get less/no movement for the initial force application and then stock spring compression rate once past the preload.

Interestingly I am not sure one or the other provides you a "better" feel or engagement percentage (or that it matters in an off on situation like the shifter because of short free length and short travel) but they are not exactly the same result.

Can anyone sum up exactly what this spring does in simple terms?

Quote:

..makes the shift drum rotate quicker, moving the shift forks quicker, moving the gears quicker, moving the gear dogs into the slots quicker, completing the shift in less time and engaging the dogs and slots more fully in less time.

Huh? If there were dogs in my engine I suppose they'd be dead by now because I have never heard them or seen any evidence of dogs inside my engine.

$22.36 seems a little pricey for a spring.

You could pull out spring and stretch it. Maybe a free mod!

I have one of the Factory Pro springs that I tried and didn't like so I switched back to stock. $12 shipped

could you give us a description of the difference to the pedal feel? please?

Ghostt · January 30th, 2015, 03:56 PM

Spring could just be worn out.

And to correctly change a springs rate, is cutting it and shime it to the original length, just like the forks of example.

To me, it was much stiffer and took a lot more effort to engage the gears. I still use standard shift and I was almost unable to pull the shifter up hard enough to shift up through the gears. It also felt like the throw of the shifter was shortened but that could just be in my mind.

alex.s · January 30th, 2015, 04:34 PM

technically speaking its not possible for the throw to change just by the spring. but stiffer spring would definitely make stiffer pedal

green_bread · January 30th, 2015, 04:43 PM

Sure, and that makes sense. I'm not sure how to describe what I meant, exactly. Maybe the stiffer spring takes some of the play out of the shifter and that's why it feels shorter? Or, like I said, it's just in my head. Haha
