depends on RPM desired.
MP2 was good up in the mid 14000 range.
Hatori SB17 closer to 15000

If you want to wick it up, go with an SB18

Thanks a bunch, I just happen to have
an MP2 but I think the extension is for
a YS. Really appreciate the help.

From what I remember (I had an MP2 on both OS and YS) the extension is universal. It'll fit both OS and YS using different mounting holes on it.
