Modern Vespa

My OEM clutch is a 5 shoes one, and I like to tune a little as the rear wheel tends to spin when the MP3 is on the stand.

I'm not sure whether to use the white or yellow springs (I think the red ones are too much) for the shoes, and if I should change the counterspring (I have the white and yellow ones in my hands) when I use them?

Thanks for the help

thats normal aftermarket springs are even weaker so it will engaged earlier

I've tried different clutches and different clutch springs but in the end went back to stock as that works best for me

It is not supposed to, that in example in Malossi small springs, the white is close to OEM, the yellow some like 20% more stiffer, and red some like 35% more stiffer? is what I can read, but can be wrong.

The main point for using different springs is that you change (raise/lower) the rpm at which the the clutch engages.

The rear wheel is supposed to slowly rotate the rear wheel.

Both of my Hondas ST1100&ST1300 with traditional clutch and driveshaft do the same in neutral when on the center stand especially when the engine is warming up (fast idle)

Today I removed the clutch/variator cover to see if there was anything strange about it. Nothing. The clutch cover is fine and smooth, and the pads are also fine and making even contact.

The strange thing is that when I opened the cover, I no longer felt any strange friction as before, and when I started the bike, the rear wheel moved with minimal movement, as it should, unlike before, when it was much much faster. Maybe it was dirt or something similar, I don't know

I'm still intrigued to see if I can make the clutch more smoother by playing with the springs, both the small ones and the counterspring.

The way I obtained a smoother clutch and less bucking was by removing 4 of the 25gram rollers and substituting in 21gram Piaggio rollers in a staggered pattern (25-21-25-21-25-21-25-21) for an average 23gram.

This took out the bucking while keeping highway revs manageable (for a scooter)

I also tried Malossi rollers when I was playing around eith the Malossi springs.

Can't recommend Malossi rollers since they wear out extremely quick.

I have very good result with the J Costa as variator, but think about smooth more at clutch level
