Jazzbutcher, Google " 12v DC UPS cooling fan ", click on "images" Plenty of choice there.You could mount it some where towards the back of the bike and pull the air through.There is a nice bit of space to the left of the rear shock. Which ever way it`s done be careful as the airflow will want to draw in the hot air from the rads. Think how the Britten motor was cooled and how he routed the air to the rad and the airbox. There are fairings available that have an intake on the leading edge, drawing in cold air and helping the ram air system to work.Sorry, must not mention Ram air System.....
Do as much as you can to block any radiant heat,
Every little thing you do will add up and help ! Even shaping the leading edge of the rear manifold heat shield to help cool the exhaust, again make sure the air has somewhere to go out.
Hope this provides some help. Good Luck. Alastair.
Great idea with the heat shield, been looking at that, don't see any reason why I can't fit a scoop on the two heat shield screws as there's a nice big air space just behind there to pull air into to cool the rear exhaust headers. It will also be effective at directing the extra fan air instead of it blowing out of that gap. I've got some 3mm stainless plate, may take a bit of fabricating to get nice but at the moment I'll rig up something rough out of alloy to try & see if it works.
Looks like I'll definitely need to alter the undertray to let hot air out.
Busy applying gold fibre tape to the insides of the frame struts at the moment, really glad it's not seen when everything is back on heh heh.
Thanks again for the ideas.
A great help & much appreciated.
All the best Paul.
