My Buell xb9sx 2009 ISSUES Full Story

[samuelseggs]

Hello, I'm sorry to bother everyone again with my issues, I have not been totally transparent about my bike issues, so i was unable to get full support,

On my previous threads i was complaining about the issues with my bike without giving a full detail about the current state of the bike, I appreciate all those who took their time to help me with my previous issue, they were of great help, Thank you very much.

I got this bike from a dealer shop although it was not new. it had about 15k miles on it

1. I had issues with the stock exhaust, couldn't really remember what went wrong but i was still very happy about the bike so i jumped on ebay and spent almost 1000USD on getting a termignoni exhaust.

2. Few months later, i started having issues with bike performance i took it to my mechanic who happens to help with my previous bikes (Hornet and Xj6) That happened to be my greatest regret. He told me the fuel pump was bad that i would have to get a replacement. so i paid to get another pump, Well he went ahead and fixed another pump but the issue got worse. I'm always away cos of work. SO i did could not monitor what he was doing... Then he called me that the fuel pump was totally condemned that i need to buy a complete pump. I got angry and left the bike there with him.. During this period i was out of the country for training and could not have the bike towed home. I told my friend to help me get a complete pump. So we got one off ebay fairly used. After removing my old pump we noticed my mechanic had already removed the regulator it was a pretty mess. We got An 04 pump instead of an 09 then thanks to lunaticfringe and other members i was able to fix the pump and then i started noticing some newer problems with the bike, The Check Engine Light was always On


When i went to pick up the bike, It was parked is a very WET Environment and was not covered, The side stand sensor had stopped working i guess due to where it was parked. So i rode home, the bike was performing even worse, it would not rev it kept backfiring, so i bought injector cleaner and filled up my tank, then poured half of the cleaner into the bike, few rides later the bike cleared out a bit.

Although i wasn't getting good rev without the bike backfiring and having funny sounds coming out of the airbox. I jumped on this platform and i was told to do a TPS reset. I did the reset but still couldn't get a good turnout. So i saw a post on how to do a self diagnostics. I got my first error, LunaticFringe gave me a solution that it was stuck self plug cleaning. I followed his instruction but still the CEL was still on. Few days later, i tried to check the error codes, I found out that the code has changed i was having new series of code


11 tps
13 oxygen
15 intake air tempera
33 fuel pump
44 Bank angle sensor
45 side stand sensor
34 iac
37 speed sensor

Current State of the bike:::
1. It would start but does not idle. So i have to apply bit of throttle, When the Bike is hot the idle becomes stable at least it would not go off
2. The bike does not have a quick response until i shift to next gear
3. Another thing when i stop at a red light on turning green the bike has this backfire sound from the airbox, i have to throttle hard to get a response

Error 37 says i have a bad speed sensor, but my odometer reads accurately (i guess)
Error 33 says i have a bad fuel pump, but the bike starts although when the bike goes off due to bad idling i get loader noise from the pump

So guys i need all the help i can get i have missed riding this bike and i'm not ready to get rid of the bike

Oh I forgot to add my termignoni exhaust has been damaged because water had accumulated inside the exhaust, after lots if reving the exhaust tore out... I could not fix the exhaust now I have my old yoshimura exhaust on it

I appreciate all your input

NB:: Sorry i may find it difficult to express myself in writing ( Bad English) or inadequate words to use

I wish i found this forum earlier
