Question regarding valve stems on Tri Glide Ultra Classic (same stock wheels apparently on 18-21 models)...
Anyone know the valve stem hole sizes in the front and rear wheels? I believe Harley wheels may have two different stem hole sizes - 8.3mm and 11.3mm.
Reason I ask is I’m getting ready to go down the goat trail of investigating retrofitting TPMS (internal) as I know the BCM and instrument cluster for my 21 FLHTCUTG is compatible...
