Oil Temp Guage
just picked up an '08 ultra classic and want to put the HD oil temp gauge in the fairing, well read alot of posts that say the best and cheapest) way to mount the sensor is to remove the plug next to the oil drain plug (the one that requires an allen wrench to remove), put in a bushing and screw in the oil temp sender, well went to local dealership and they said under no circumstances should i remove that plug for some reason or another.. my question is does anyone know what this plug is for and will it really do any damage if removed. I figured worse case if i remove it and strip it out i have to buy a new oil pan. Opinions please.

I would never use Teflon tape anywhere in proximity to drive-train lubricants. You don't want fragments of tape floating around and clogging oil galleys.
The Napa adapter is #3220 x 6 x 2 (1/8F-3/8M). In removing the Allen plug, don't force it. It has threadlocker from the factory and may resist removal. If a modest amount of torque won't break it loose, heat it up a bit with a heat gun or hair drier to weaken the threadlocker.

I'm a first time Harley Davidson owner last year, and I do my own oil, fluid & lubrication changes. Never had a problem with a leak after changing fluids. Clean drain plug thoroughly and install new O-ring (all 3). I use a dab of teflon metal paste on plug threads. Tighten to spec using torque wrench. I've never had a problem, and so can you!
