Decel pop and DTC codes....

[mstngjoe]

Will decel pop necessarily cause a DTC code?

I just starting getting some pop on decel and sometimes between shifts.

Only mod I have is the KW slip-ons which I've been running for about 1500 miles with no issues.

I've tightened all exhaust fittings and there is no DTC indicated.

Any chance bad gas could cause this?

Bike has 3200 miles on it.

Had a dyno done after installing Rush 2.0 earlier and the a/f ratios looked the same before & after install.

I just put a fresh stock air filter on last week. I had the air cleaner off trying to see how difficult it was to get at the intake bolts. Didn't put a wrench on them yet.

The weather here has been unusually hot (95*+) this past week. I thought that may be a contributing factor.

I'm going to get a fresh tank of gas from a different station. I may try some gas treatment too.

I'm hoping to get on the dyno Friday for a baseline run and confirm a/f ratio.

Thanks for the reply Hobbit.
