progressive springs

[sweptail]

hi folks. i have z900a4. i have just taken out my standard fork springs to replace with Progressive springs. Trouble is, the pro`s are about two and a half inches longer than original springs,which worries me. Can this be right. It will take a hell of an effort to get them in i would say.havent measured them yet. Also, do you think standard 10w oil is sufficient for these new springs? Cheeres Tommy

it says z900 on the tin.

Sweptail, two & a half inches longer than the original springs! Sounds a bit much, I would seek advice from where you purchased or a m/c mechanic in the area. Even if you got them in, I think they would be too hard.

Unlike the Z1/A/B the Z900 springs have a spacer (44028-039) between the spring and the cap bolt which if I remember correctly is about 2" long.
I wonder if the new springs are designed to be fitted without the spacer?

Don't assume anything, check with the supplier before fitting!

thanks, lads. The spacer theory is worth looking into. Tommy

Something else to consider - the old springs will probably have "squashed" somewhat, making them shorter, though I can't see them getting 2"1/2 inches shorter. There is a "service length" given for them in the Kawi and Clymers manual too I believe.
