unusual to see a new thread / topic in the gspot after a while....
anyway, I am going to suggest the driveshaft in the paralever.
Years ago I pulled mine and when re-installing, I didn't aline the UJ's correctly (there are a few other topics in here about that)
The caracteristics of the bike changed some what, would fall in to right hand corners and I had to really work it to turn left.
Whilst you note you haven't done anything to the paralever, I am putting forward that there could be wear in it that is causeing the pull to the right.
I suggest that you check everything else first, start with the simple items and work to the harder. (Its not hard to pull the drive shaft though)
