I'm fitting my first set of Wössner pistons and I have noticed that they are somewhat wider inside compared to Kawasaki and Wiseco pistons.

I have a set of brand new original Kawasaki bearings that I was going to use but the side clearance seems a bit big.
I also have a bunch of aftermarket ones that came with various rod kits and they are a little wider.

Kawasaki (Left): Total width 21.7mm, Roller width 17,5mm
Other (Right): Total width 22.5mm, Roller width 14mm

I never liked the aftermarket ones because of the short rollers.
So, what do you guys do for wrist pin bearings when using Wössner pistons?


.

I bought new Wössner wrist pin bearings and used them. I've never seen any significant wear or damage on a used wrist pin or bearing, so I wasn't concerned.

Use the longer bearings, the short ones can slide almost half way out of the rod.

I got the silver plated small end bearings from Fast from the Past (they are extra)........they are much better looking than the stock type ones I got with the New Crank and new IMS Rods........thats what I have in my bike

Thanks,

Thanks Jim, I didn't know those were the Wossner bearings from Fast from the Past.

Jim Hinshaw is a Wössner dealer, and his company is Fast From the Past. I always assumed the wrist pin bearings he sells are Wössner brand, but now that you mention it, I have no idea if Wössner even makes wrist pin bearings. I'm using FFTP bearings in my H2 and it hasn't come apart, so I guess that's good.
