Question about Harley Davidson FLHTCUI Electra Glide Ultra Classic Motorcycles
Just had a set of Vance and Hines true duel pipes fited and a high flow HD air filter along with a retune using a screaming eagle race tuner problem is that now what sounds like the throttle position sensor is very noisy when i turn the ignition on ( sounds like it is going to full on and back to off ) , is this due to the retune , the lack of the original air filter back or is the position sensor on the way out . The bike seems to running ok starts well and definatly has more low to mid range power and the bonus of better fuel economy , the engine fault light and security light both go out after the prescribed 4 secs so there seems to be no faults , bike is a 2007 FLHTCU .
Are you sure it's not the idle air valve as they can sound louder after changing to a high flow filter...take the filter off and shine a light in the intake when turning the ignition on and off. The idle valve is just inside the intake in a hole at the top...see if it moves in time with the noise that you hear

Hi Ken, my 2001 RK did the same thing until I had the Rinehart Tru Duals and mufflers put on AND a Thunderslide with Dynojet jet kit. That was the big problem the stock slide even though Harley supposedly reworked the carb when the 95" big bore kit was installed. Well it had the wrong jets and the stock slide. I have 35k miles on the bike. It now dynos at 82HP 94 Torque at 96 degree air temp. It runs great and no pops, backfires or misses except at slow speed because of the cams it will lope or surge.

I've heard great things about the Terry components tuner but havnt used one yet. If u plan on doing any motor work or anything in the future I would use the hd super tuner. The power commander is also really nice and there are alot of maps available online for free. If u have a local dealer or shop u like using, see what they prefer to tune with on their dyno, that way if u have an issue with the bike they will be familiar with the component. Good luck!
