xb9sx problem

[05xb9sx]

Hi guys-love the forum-great info. k here goes-bought the bike new, and have had all the service done at the proper intervals.About 6 months after I bought her had a weird pop through the airbox,the engine light came on and it shut down- let it cool down for an hour or so and wnt on my way with no problem. Called the local dealer(Deeley HD Vancouver BC)and got it into dealer the next day.They reset the tps and looked for codes but nothing showed up.They said no problem- just ride it. Rode for the remainder of the year and was great.Brought it out last spring and after a couple of months did the same thing but this time allmost lost it on the freeway (70 miles an hour!)very scary.This time called Deeley again and they asked if i could wait almost a month to look at it.Needless to say told them to take a f'ing leap off a short peir.Called the other local dealer (Barnes HD Langley BC)and they told me to bring it in the next morning.cool. They hooked up the comp and did their thing and no codes agian.hmm.The buell tech was baffled- and got on to the official HD tech board and found a related problem with another customer's bike(temp sensor-rear cylinder head) the sensor thought it was hotter than it really was and it went into skip spark mode(heavy)they replaced it for me free of charge and it has been perfect......until now.... last weekend took the wife for a ride and it did it again..crap... but this time it was violent (skip spark)on off on off blip the throttle and it would go away...got us home finally.

If the skip spark has a light and heavy , why would it go into heavy right away and the fan does what it wants when it wants...crazy. Of course the bike is not under warranty now and is really pissin me off.Replaced the temp sensor and disconnected the battery for a couple of hours. When i fired her up the fan cycled (?) and the bike ran really rough and the check engine light comes on and off .

Any ideas --- any help would be really appreciated.thanx
