Loose fuel injector plugs

I recently removed my SERF and fitted a TMax auto tune system.

While doing the unplug and replug the injector plugs I noticed the plugs on the injectors turned

.

Can anyone tell me if this indicates loose injectors or is that how they are?

Thanks for ya help!

That's the way they are....o-ring seal will allow injector to move a little...clip holds it in place

Thanks a lot kdietz,
I have fairly bad decel popping going on since fitting the ThunderMax unit and wanted to eliminate that as a vacuum leak. Looks like I will have to pull the exhaust and put new gaskets in.

Hiya Ron, Nice ride bloke!

Did you have the decel popping problem after you fitted your Thundermax too?

I have tried the fuel cut feature at various cut in and cut out rpm's without much luck. I sent my map offsets to the techs at Zippers, they could see nothing to suggest it had an intake leak. That is why I thought it may have an exhaust leak. I had to remove the exhaust to modify the angle of the rear O2 sensor bung for the larger WB O2 sensors. I didn't have gaskets so just put it back on with the old exhaust gaskets. I cannot hear any ticking or see anything else to suggest there is a leak. The RB Racing exhaust has square shoulders unlike the harley exhaust with the rounded shoulders so the tapered HD gaskets are probably not ideal, I should try to fing some square gaskets.

What did you do to tune around the problem? My AFR is set at 13.8 by the base map.

Thanks,
Bluey
