【DAYTONA】Super Clutch Center Spring Review

Just Right Rate

The rate of the center spring that comes with the KOSODrive kit is too high, and while it is quickly good for acceleration in town driving, the rate of the center spring is too low.
I wanted to reduce the rate because the normal RPM is too high and the Damage to the Belt is too large and the fuel consumption is too low.
Before the replacement, Belt had about 5,000 km when using the KN project, and other than that (including OEM) However, after the replacement, the Belt has been able to run for 10,000 km without running out. (It looks like it can go 20,000 km in terms of wear and tear)
When accelerating at full throttle KICKDown, the Large body shifted at about 8000 rpm before the replacement, but after the replacement, the Large body shifted at about 7000 rpm.
However, the Sensep is not too soft and the shifting is not too rough, and the acceleration is now very natural and smooth. (Although there is also the effect of SliderBearing combined with Center spring)
If you want to drive a Scooter as a normal foot pedal without any discomfort, this level of Rate is better. View detail

Replaced to stall on a hill

LIVE DIO suddenly stopped climbing hills that it used to climb with no problem.
The RPMs don't go up at all and it stalls….
I decided to replace the Spring because I thought it was not shifting properly as it was climbing from a 0 start.
Incidentally, parts such as WR, Belt, Clutch, Torque Camshaft, etc. are not climbed with new ones replaced.

The OEM ones were still available, so I was torn between them and the OEM ones, but I decided to go with DAYTONA ones because I knew they would eventually wear out and I had read in the reviews that they do not run out of heat.
The length is about 5mm longer than the OEM one, and I feel that the DAYTONA one is stiffer when pushed in by hand.
When attaching the Belt, I opened the Clutch by hand and had no problem.
On the important slopes, the rpms, which had not been rising before, are now rising, and the car climbs up the slopes as strongly as before.
I can't compare with new OEM springs, but the symptoms of not being able to climb hills with worn out springs were cured by replacing them with DAYTONA springs.

I would like to see a paint job that makes it easier to tell what Spring is attached to the Clutch, even when it is assembled on the Clutch, so that the color of the drills can be more clearly identified. View detail
