The Fan !

Has anyone (Hizzo?) looked for a better, more efficient fan, and/or ways to improve the radiator air flow?

yep, cleaning it helps a lot. my friend pressure washed his VFR radiators and now the fan doesnt turn on very often. i'd remove the fan and would be extra be careful where i spray (from inside to front of the bike).
didn't try it on my yet though

Have you actually looked at it? I mean, have you looked for a 12V fan? I know there are 110 volt fans for old computer systems (you know, when they had a megabyte of storage on 8 hard disks). I imagine that there is such a fan to be had that will work on our bikes. I haven't looked yet. Maybe Grainger or one of the scientific supply catalogs...

somewhere on some site in the past few days I saw a fan...I'll try and see if I can review my history tommorow and see where I have been. I wasn't giving a fan much thought at that time or I woulda remembered it, but I'll see what I can do

yeah i found a few.... but specs werent high enough for me to feel safe. i figure the fan is doing a minimum of 200 CFM's with the restriction of the radiator. also the shroud isnt very well designed (more of the culprit) and it sucks alot of the air form the sides of the fan. i believe a better design would prove stronger results then just a higher power fan. Also since this is such a custom designed fan to begin with (i am sure its not used anywhere else nor the parts) so i have no idea of the power of the motor. Now the other day when looking up winding for the stator (still working on v.2.0) i saw this thing

http://www.flyelectric.ukgateway.net/cdrom.htm

i think that we could create some interesting results with that... too much of an undertaking though for me an my wallet after my stator junk... still dishing $$$ for R&D so i can measure temps and stuff to give better estimates then i think....

So perhaps a better design of the shroud?

Those brushless motor ain't cheap!
They were starting to become more popular just when I was getting out of RC race trucks. No doubt they've come down some in price since then (about 12 years ago or so)

There is an aftermarket fan availible for the VN750. I thought Dennis Kirk carried it but I can't find it right now. The after market fan has metal fanblades and I think had an extra fanblade
