Modern Buddy

So I finally made a move on a new frame for my Stella after the amazing Chelsea at scoot Richmond tracked down a blue one for me!

I'm looking at putting my heavily modified engine in, but the blades on the flywheel fan broke. Is the fan something that can be ordered separately and mounted onto my old flywheel or do I have to buy an entire new flywheel?

If so any thoughts about the performance lightweight flywheels?

There are two different styles of flywheels used on Stella's and I'm not sure when they changed.

I have a 05 and I swapped parts between mine and another bikes messed up flywheel, I'm not certain if it can be done with the newer style flywheel. I'll try and look when I'm down at the shop next.
