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.,,

What temperater should fan turn on and i know the problem isnt the fan what should i check next


the temperature of speed motorcycle is over 100 degrees Celsius. Between 100 and maximum 110. In cooling system you must have antifreeze all the time, because this boil higher than 110 degrees.
If the fan start higher than 100 degrees, is ok. But i guess until 110 degrees. Search by internet the manual for full specifications.

Cheers.

Hi,how can i check that my coolant fan is working ,it got to 100 degrees and it didnt cut in ,thanks


the fan wont cut in till the engine is very hot,,, well over 100 degrees near to 120! if you realy wont to test the fan out pull the bike up on its stand and leave it ticking over,,, it should take forever before the fan kicks in,,,my bmw has only ever switched the cooling fan on once in 3 years!!!! and that was after standing with the motor running in a traffic jam for 35 minuets !!! but if you wont to find the temp switch pull the plug off the switch and short the two plug pins out with some wire that will start the fan up,,,watch your fingers,,,you only get 5 free fingers on each hand with each body,, and there are no spare parts going cheep?

Over heat ?


Normal operating temperature on the bike should not go over 220 degrees F for very long, even in stop & go traffic. Riding down the highway on a hot day you might be 190 F. At start up there won't be a reading until the sensor gets over the minimum which is probably around 100 degrees. You should be able to see it rise after a minute or so of idling. You should hear your fan come on around 190-200 degrees. Your thermostat probably opens at 180, allowing coolant to flow through the radiator and if that does not cool the bike enough the fan comes on next.

"Temp problem with 2008 Ulysses"


Seems that it has a defective engine temp sensor. This is a very bad problem. It also requires a special socket to remove the sensor. Good Luck!

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.

Ulysses quirks


I purchased a new 2006 Ulysses about 3 weeks ago great bike but have 2 niggling issues: 1. that damn noisy fan 2. heat on my right leg is more than comfortable Has anyone got any remedies to these problems?1. The fan you can do nothing about. Its very needed but yes it is noisy. 2. The heat on your right leg is a factory standard option. Also not much you can do about it.You could get your header pipe Jet Hot coated and it lowers the temp at your leg a little.,,

Did you check the charging system? Sounds like when you ride it the battery drains. Could be you are drawing more amps than it is putting out. Sometimes folks run a lot of accessories, extra lites/ heated garments/etc on their Ulys. Once sitting for a few days it builds up enough to start.

Cooling Fan Acting Up


in that it doesn't run like it used to hasn't started up while riding in 95 degree days and after I shut off the bike it may or may not start and sometimes starts a few minutes after I shut it down, at which time it sounds like it is struggling for a few seconds.  The blades spin freely when I spin them manually, and I can't find any troubleshooting procedures in the manual. ,Check the fuse and the temp sensor.,,,
