Can you convert a air ride front end,to a sealed I guess it would be progressive ride by plugging off the air access hole in top of fork bolt

 

Really need to figure this issue .fellas first bike trying to do as much wrenching myself!! I have a complete front end off a 09 Rk.that I was gonna just swap tins and stab it but the lowers rant chrome and that trick in reflector...I'd rather not have to sport..

 

Yes you can Just cap off the line or put a bolt in the top caps . Did this on a 1988 FLHS. I never did notice any difference with air pressure in it or not . At that time you can change any of the fork internalsyou have a mind to .
