I was looking into the Factory Pro Blue Magic Spring which helps with false neutral, and gear selection problems. It's a stiffer spring in short.
From the Factory Pro website

"The Blue Magic spring"
Positive feedback rating
This kit includes the new F-Pro Shift Spring.
That's it. A carefully fabricated and heat treated spring.
1-2 minutes to install.
1. Remove bolt and old spring.
2. Replace old spring with New Blue Shift Spring.
3. Replace bolt.
4. Shift better and find neutral easier.
The price is what I have an issue with, also from the Factory Pro website,
The Blue Magic Shift Spring
$16 + shipping
(yes, in good humor, it's $14 for UPS Ground, even for a little blue spring - and we have to ship it tracked and insured. I can't just drop it in the mail and hope and wish you get it and no, I can't send someone down to the post office to mail it Priority tracked and insured)
You could pretend it's:
$30 and Free UPS ground shipping!
$30.00 USD is a bit steep for a small spring.
So I did some research and came up with possible alternative, and it's a lot cheaper.
Kawasaki is know to use the same part for multiple bikes, the spring is no exception. So after some quick research, I found this spring, and it's many uses
Purchase this Kawasaki 92081-112 SPRING --- SPRING, SPRING, NEUTRAL,POSITIONING
This Kawasaki 92081-112 SPRING is used on these models and components:
Funny thing is you can see it was used on the earlier model Ninjette, along with other bigger models.
But if you look up the same spring, but for older model Ninjette, you don't see the large crossover
Purchase this Kawasaki 92144-1580 SPRING --- SPRING,NEUTRAL POSITION
This Kawasaki 92144-1580 SPRING is used on these models and components:
So I find this interesting to say the least.
So I found part#92081-112 on eBay for dirt cheap, and ordered it.
Upon inspection between the two springs, I noticed that the alternative is a little bit longer, and finger pinch test it was stiffer.
Okay time for some numbers, as in measurements
1998 Ninjette OEM 92144-1580 SPRING
So the spring is technically bigger, and it's stiffer. Installation was a breeze.
Okay I can say it felt better, more firm, positive shifts, while a little bit more effort to change gears.
So there's a definite difference between the stock Ninjette vs 92081-112 .
For now just by feel, it's a difference in a good way, so I'd say it worth the money for this spring
So I'm happy with the 92081-112 spring, and maybe it's a cheaper alternative to the Blue Magic Spring, but definitely worth trying this one first, before the Blue Magic Spring.
