I was concerned about my 04 VFR heating up in traffic and at slow speeds. I heard about a VTR 1000 fan mod to fix this. I was asked to post steps and results so here they are. I am a 25 year veteran professional mechanic and have been riding and repairing my own bikes for over 30 years. I did this the long way (no short cuts) to see how long it would take using basic tools and it took me about 1 hour to complete taking my time and stopping to take pictures. I can say it makes a very big difference as the temperature drops very quickly now as opposed to going up until you get moving fast enough to overpower the fan with incoming air. When the fan kicks in and you start moving it cools down as it should. The steps for anyone who hasn't done it or is unsure how are as follows: 1. Remove the front cowl at the front of the fairings; 4, 10mm bolts near the bottom and 4 black button clips (2 on either side by the forks). The bolts holding the cowl are shorter than the fairing bolts, to make it easier to figure out what bolts go where, cowl, fairing etc, set bolts from each section in different piles or cups. 2. Remove the left side fairing; 7, 10mm bolts (4 long around the front, 3 shouldered at the middle/back) and 2 button clips underneath holding the fairing halves together. 3. With the fairing out of the way remove the bolt underneath and behind the radiator to remove the lower radiator bracket. 4. Remove the bolt to the rear of the radiator and easily (it is only aluminum) pull the radiator toward you to remove it from the locating pin. Leave the radiator hang, it doesn't go far. 5. Unplug the fan connector and the single spade terminal from the temperature switch terminal making sure not to break the switch 6. Remove the 3, 10mm fan bracket bolts, one is underneath, the other two are hidden by the fan shroud at the top of the radiator. They can be accessed from the bottom or the top with a 1/4" ratchet and deep 10mm socket. 7. Drop the fan assembly out to the bottom and remove the fan blade, 8mm nut, making sure not to bend the motor shaft. My blade was a little difficult to remove as the fan blade appeared to be locktited on. Use a screwdriver and work one side then the other to work the blade off of the motor shaft. I ended up breaking the center out of the fan blade. No great loss as I didn't plan on putting it back on. When reinstalling the fan assembly make sure it goes in between the radiator and the fan shroud and with the long leg in the upper right. 8. Reinstall the radiator assembly, plug in the electrical connectors, reinstall the fairing, and the front cowl. The fan seemed to be a bit louder but nothing that concerned me, I like the better cooling. The new blade also moves a lot of air compared to the stock fan. Someone had complained in another forum about the warm air heating up their leg but I didn't notice anything different, maybe when summer hits it will be different but again I like the better cooling. If anyone has any questions or if I missed anything let me know or make corrections. Enjoy the upgrade I know I will feel more comfortable not pushing 227*+ in stop and go traffic.
