While the bike is apart for painting and other modes I am lining the inside of the frame with Thermotec and then decided to mock up a defector of sorts for the fan. The design intent is to route the fan exhaust down and out below the swing arm. Looks like it would be easy to mount this up in light gauge aluminum sheet or even a stiffened section of Thermotec material. The pictures don't show it real well but I believe there will be adequate space for the air to move down and out.

Be careful you dont get too close to the exhaust side of the fan. It need some clearance or the CFM's will be reduced and although you wont feel the heat it wont be removing nearly as many BTU's from the rear cylinder |

Not only that, but I think by design the stock airflow provides a dual function to also carry heat away from the rear shock. Your deflector would prevent airflow around the rear shock. You'd be suprised how much heat is generated within the shock and reducing the airflow around it may shorten it's life. BC Steve |

Well I will give it a try...it will be easy enough to remove if it causes a problem. One thing for sure is there will be considerably less heat baking the seat. Ultimately if the fan cannot move enough CFM 's and reduce the engine temp then it will run continuously. That will be a sure sign this mod is a bust. As far as the shock goes I think it gets absolutely baked by high temperature of the air coming out of the fan and regardless of airflow I would think the shock may last longer not having the the extreme heat of the rear header being blown over it constantly. I agree with you Steve that shocks do get warm doing their job. Our XB shocks are under some severe duty being blasted by the fan. Anyways, just a bit of "idea engineering" to potentially improve upon the heat issue at the rear jug. |

You might try enlarging the sides a bit so that is kind of follows the lines of the shock more if that makes sense. It would allow for more exhaust from the fan while still keeping the heat off the shock. |
