Hi fellow buellers, At 20k kms, the fan on my XB12 starts to run heavy. It allready burned through 2 10A fuses, replaced it with a 15A fuse and this one seems to hold. however, it just seems that the fan blocks every now and then. it doesn't run as smooth as it used to. Can anybody help me out on how to gain access to this very much hidden and build-in part? Perhaps the answer to my question is somewhere in the knowledge vault, but I don't seem to be able to trace it,... Thanks a bunch! | ||

1. Raise motorcycle from muffler. 2. Remove seat. 3. Remove upper shock bolt. 4. Remove fan. | ||

5. Replace 10A fuse! | ||

Test the fan with a 12V power supply before you go ripping the bike apart too far. Disconnect the fan connect and place 12V on it. If the fan doesn't spin you know it's dead. If it does the fan isn't your issue. | ||

24K on my 08 Uly, fan started running slow several weeks ago, but I also noticed that my dash lamps were dimmer than they used to be. I suspected an electrical problem (maybe bad battery, voltage reg, stator, or connectors in charging system), but the dealer found that the rocker arm cover was leaking oil and gumming up the fan, so the fan was drawing too much current struggling against the added friction. They replaced the fan and battery, and freshened up the leaky seal. Extended warranty covered all but the battery. Bike's running great again. | ||

addendum: That's 24K miles, by the way. Also, the dealer said the fuse was melted (though not blown). Upping the amps on the fuse is not a good idea; that's like putting black tape over the check engine light... | ||

Just a little more explanation: I've gotten into the habit of turning off the engine at the end of a ride by just flicking the red button with my right thumb, to keep both hands on the bars while getting the bike into a good parking position. That's when the fan and dash lights come on, and when the fan started struggling, the lights got noticeably dimmer. The battery probably went bad due to multiple deep discharge cycles because of the struggling fan. |
