Does the YS90 require a separately purchased fan than the one supplied in the R90SE kit?

Does this mean I have to order something? Damn!

Where can I find this fan if there is a different one required - I couldn't find it on Rick's or Heliproz?

yes and no. the ys 91 has different threads than the os c-spec so yes it needs another fan. However you can get a thirty dollar fan or a five dollar tap. You can tap the fan that comes with the kit, get a different fan, or get a c-spec ps

I have the YS/SE combo and went with the tap. The fan is made for OS and is 5/16-24 thread. The YS is M8x1.0 5/16 and 8mm are practically the same size and the pitch for each is very close.
Running a tap through the factory supplied fan is easy to do. It really just massages the threads a bit to fit the YS metric crankshaft.
I got my tap from the local metric supply house for about 10.00

I used the os fan

used an old ys61 and stuck it in a vise, and used it to spin the fan on first. Just be careful to keep pressure on it, and keep it straight.

Then it went right onto the ys91.

I would suggest using a tap though!!!

But this way did the job for me.
