I need some help from the "laptop wrenches" out there concerning a slight issue with my FBG. She is a 2005 pushing 17 K and I currently run the PCIII with the O2 by pass, Jardines and the recommended Jar tune in the PC, under tank K&N, and the secondaries removed. The bike runs great other than some popping on deceleration which has never bothered me. The problem is in the idle. The bike will run great for about two months. When fired rev's to about 900 rpm and quickly settles in at about 500 when warmed. The problem first starts with bike only going to about 500 rpm when cold but still runs fine when warm. The next phase is the bike still hits 500 rpm but stalls usually at the first stop light when cold. It always fires right back up and soon as this occurs I run a 12 minute tune and the bike is fine again for another couple of months. Upon talking with TxRIIIRider in ES we found that our bikes had the exact same symptoms and I believe his eventually required a trip to the shop if I recall. (Dave please comment if I am correct.) Yesterday is what prompted this post. I rode the bike to work idling at about 500 rpm and it was fine. I went to start it to go to lunch and it would not idle at all. You had to keep her thumping with the throttle or it would die. The same thing occurred on the way home in the afternoon, but it started to run better when I hit my driveway, again idling around 500. I did a 12 minute tune today and she set and idled great all the way through the procedure. Since the 12 minute tune is only a temporary fix here, is this a PC tune issue or do I have a primary TPS occasionally acting up. I am going with the triple K&Ns under the claw in the next couple of weeks and this would be good opportunity to change the sensor if necessary. Thoughts or suggestions are welcome.
