This came in the post today, just got to find the time to tear into the RF to install this as well as a number of other mods I've got on the cards.

A new Muzzy 6 blade fan, apparently a higher air flow and a hell of a lot quieter than the 5 fan stock plastic thing my bike came with.
Only $51.55 posted from Muzzy HQ @ Connecticut.
Just thought I'd share the pic. I'll put a photo of the old & new fan side by side when I get the time to install the bloody thing (maybe during the week if i can motivate myself, or more likely next weekend as I'm working way too much this upcoming week).
