[ST] front preload

["Marc Van Est" <MarcVE@xxxxxxxxxxxxxx>]

I'm no expert on suspensions, but here's a word of warning:

Don't dial in too much preload on the front of the RS. I let a mate set up my static sag. He wanted to dial out 5mil of front sag. 

We upped the preload till we got the sag where he said it should be (25mil if I remember right), and I took it for a spin. Seemed better -front felt less "spongy" than before, but there is no rebound damping adjustment on the front, so we had to leave as is.

The next day I took it for a blast to Darling, a very bumpy surface. Coming out of Darling I hit a series of ripples in the road at about 160kph (which I've done many times since and before) and the bike went into a major tank slapper.

I absolutely S%$t myself, had to pull over afterwards to let the shakes go away. For a few seconds I thought I'd loose it, thankfully I didn't panic and grab the brakes or tap off or I think I would have come off.

Went home, dialed a bit of preload out, went back and tried it again and no wobble.

It never wobbled again.

The only thing I can think of is that either the suspension topped out in the front, or the preload overwhelmed the damping.

cheers
