Pictorial of the Throttle Position Sensor (TPS) Modification
I did this today...
The idle was down to 800rpm after putting the baffles in the Pipe Works shorty cans - it was open pipe Harley LOUD.
It was sneezing like a cat on downhill throttle off and roll-ons - cat-choo - ran kinda gross - was lumpy and grumpy.
I put the idle up to 1100rpm -ish...
Next tried the TPS setting and it was not going up top until 3000rpm.
I setup the TPS to go up just off idle - 1400-ish and locked it up.
The feeling and throttle response is so much better, no more struggle, it likes the extra fuel.
No sneeze, no pop, no bang...
Idles sweet, pulls from down low, no problemo.
Very nice change for the better.
Makes me wonder what the previous owners were doing, other than cosmetic tuning?
I like it - nice and sweet
