I struggle with bar position too.
I'm pretty sure seat is std issue but it's not hard now.
I didn't do work, I bought bike used.
It had fallen on stand and been refurbished with paint, exhaust can, seat, etc to my best knowledge.
Anyway, seat has gel underlay. Works a treat. Looks same as std except when pressing upon fabric, anyone could feel her absorbance .
Doesn't stick, butt slides just as easily as std cover.
Looks like std cover anyway, simply with gel underlay.
I like it.
Note: maybe another option? Std seat with gel contours creating a gel sandwich.
