Question about 2007 Buell XB12X Ulysses

2 Answers

Fan cooling Just brought home a new to me (2100mi used) Ulysses. 50 degree day 35 miles on the highway to get home and I was surprised the fan was on when I pulled off the highway ramp. What should I expect as normal for the fan on/off? I know it's supposed to be triggered off the rear cylinder temp but I'd have thought riding at speed with engine turning between 3500-4500 rpm wouldn't require the fan. The dealer I bought the bike from doesn't know much about the product. I guess I can check the guys in the shop but I thought I'd check owners' experience first.

I have a 2007 Buell Ulysses, 24,000 miles. I agree with tina783 and use synthetic oil. On my Ulysses the fan comes on when the engine temp calls for it, if you hear it running, all is normal. Mine will run on cold days when stopped in traffic, after exiting the highway, etc., hot days it will run unless I'm going fast enough for the moving air to cool it without the fan. Only problem I've had is when the fan motor failed, if you DON'T hear it running when you think it should THEN maybe something is wrong. When the fan motor failed it blew the fuse and lit the check engine light. I noticed that the fan was not running when I stopped so I checked and replaced the fuse. The fuse blew again so shut the motor off any time I had to stop and got it to the dealer for a replacement fan (under warrenty at the time). Otherwise it's been a great bike.
Enjoy your Ulysses! I do mine. (And my son bought one last week too!)

Doesnt sound like anything out of the ordinary.  The only things you can do to help remedy that more is run synthetic oil get a right hand side air scoop or cut vents into your undertail panel.,,

Coolant leaking out the he radiator cap

Most likely:
1. radiator fan not turning. Check cooling fan fuse. Check loose/disconnected electric cable at radiator fan. Fan may be burned out.
2. Turn ON engine with A/C OFF.
3. Turn ON A/C to see if radiator fan starts up. It is supposed to turn whenever the A/C is on.

Few other possibilities.

Fan kicking in too often 1998 f150 4x4 4.6 tow

If the engine is not over heating then it is doing its job. The constant cycling is based on the temp of the air traveling through the radiator and the a/c condenser not the outside temp so much. The start up high rev is just how these clutches work in ford fans. It sounds like it is operating correctly.

Cbr 600 fan stopped working

ast the halfway mark isnt overheating. Any bike will rapidly increase in temp when stopped or moving slow. the fan will not kick on until the bike reaches around 220 deg. Im not sure how that relates to your gauge as Im assuming you have just a C and H with a few lines between., but Im sure its near the upper range of the gauge. I would think your bike isnt hot enough for the fan to kick on. I would let the bike get a little hotter and see. If the fan hasnt kicked on when the needle reaches the upper portion of the gauge, take it for a quick spin to cool it off, dont just shut it off as that will actually create hot spots within the motor, and then consider either the fan is faulty, or the relay. You can pull the fan and test it with a 12 volt battery. One hot, one ground. If it works, it must be the relay. I doubt the stall has anything to do with the bike running warmer, unless it is truely overheating and you have antifreeze pouring out of it, then it might be. You might just be in need of a good carb cleaning.
