Does H series use pilot bearings? The Helms doesnt mention anything about one. Also seems like there is no space for one on the Fidanza flywheel.

 

well they have a bronze bushing which cannot be bougth separately. it comes with the flywheel.

 

Devine: If you have purchased a Fidanza flywheel and see no pilot bearing then you have the generation 1 model. These were produced before they experienced a few problems with the H22 engine shaft vibrating excessively and causing some bends in the aluminum. It's not a big problem, but can cause a problem over time. I had that one, and exchanged it (it's a pain in the butt though) for the generation 2 model which incorperates the bearing on the flywheel in the design.
