Author Message   Sportster_mann Posted on Friday, July 22, 2011 - 11:19 am:        I have decided to experiment with putting a fan under the seat after a particularly warm trip into a local town on my CR. I have an XB cooling fan that I am going to try to fit to the undertray ( if it's not too big ) - I intend to cut a hole to get some air through. So - do I suck hot air out from under the seat or blow cold air in ? Just wondering if one method will be more efficient than the other ? Hopefully it will just be a matter of reversing the wiring on the fan to reverse the airflow.   Hybridmomentspass Posted on Friday, July 22, 2011 - 12:40 pm:        Im not an expert, but my logic tells me you'd want it blowing away from the seat towards the back since that will be the way the air will naturally flowing when moving on your motorcycle. I think if you were trying to bring in air from the back of the bike and move it forward it would be harder because it is fighting the air that is moving front to rear. Just my thoughts, good luck   Nuts4mc Posted on Friday, July 22, 2011 - 12:54 pm:        see here scroll down...the builder describes the fans as blowing away from the seat ( sucking the air through it - note the sheet metal sides that force the air flow thru the radiator: http://www.bikeexif.com/aprilia-rsv-taimoshan good luck   Zac4mac Posted on Friday, July 22, 2011 - 09:22 pm:        That is a BEAUT-i-ful motorcycle. I bet the fans are a big drain on the charging system tho.. Blowing out the back should help a lot with a hot-seat. Make sure you can turn it off in the winter, don't want to freeze the twins.

If you want to reverse the direction of the fan flip it around.   46champ Posted on Monday, July 25, 2011 - 12:28 am:        I read a bunch of the comments and a lot of people had a problem with combining old looks with new tech. Isn't that the definition of Steam punk?   Dannybuell Posted on Monday, July 25, 2011 - 01:45 am:        46champ: I was just introduced to steam punk a few weeks back, from what I saw of it you are 100% correct.   46champ Posted on Monday, July 25, 2011 - 02:27 am:        Dan we need to go riding we live like 50 miles apart.   Gemini Posted on Monday, July 25, 2011 - 09:43 am:        some fans will spin the opposite direction by simply reversing the wires. other dc motors will not due to moe complex internals that just a motor. the other bigger less though of issue is the fan blades are not designed to properly move air if spun backwards. if you wish to change air flow, turn the whole motor(blades, motor and housing) around.
