Light Flywheels Again.

[koko64]

 While billet alloy flywheels for IE bikes need to be excellent quality to be safe from stripping the splines, and I trust Nichols engineering, any other sources you trust besides machining down the stocker? SSR make a billet stainless flywheel for EFI bikes that looks like it should be strong enough. I have seen their alloy flywheels for splined shaft motors but I have heard of some brands stripping at that connection point on the shaft.
Any insights?

SSR is the one that caused my wngine to be kaput, albeit in aluminium

Thanks mate. I'd heard of that too. Bikeboy mentions it but doesn't say brand except for Ducati Performance.

I have prob 1000 miles on my Yoyodyne alum flywheel. Love it, No problems- still has stock single nut over it. It was a very tight fit onto the crank. In fact, I had to tap it all the way on w/ a mallet onto a 2x4 as cushion. In that process of tapping it on, the thin washer behind the starter gear slipped outta position. Once together it made a metal dragging sound and would not run. Tail betw. my legs, a friend helped me truck it up to Racing Sport Services in Braselton Ga for Chris "Hippie" to fix right. He said it's a common mistake on re-installing flywheels.

The DP flywheel on my old Superlight looked like a YoYodyne unit. No issue as it was  a carby flywheel that bolts on. .  Did they ever supply Ducati or was it an Italian company?

I might work mine to have it ligthened . . . or a Nichol's  . .  have an insider looking for a DP original NIB

I would pay extra for Nichols quality. If their flywheels are anything like their clutch baskets, then that's what I'd do.

Those pictures persuaded me to just lighten the stocker flywheel. Had it done on my project bike and on my 900ssie. Perfect balance of lightness and low speed temper.

What you see here is two stock flywheels, before and after. Approx 2 pounds removed, and a polished work of art too!

Its nice to have Nichols HQ 5 minutes from where I work.. Things become so much easier.
