89 FLHS, how low can I go without interference problems

I already put a 1 1/4" drop kit ( one of the metal brackets kind that moves the shock back and down ) and I have on order 1" drop (12") shocks.
Any guesses if being this low will cause any motorcycle to other motorcycle parts interference?
With the 1 1/4 drop block, I no longer feel like I am trying to forcibly know the bike in a biblical sense . 30" inseam to the stock height was simply uncomfortable but, the full 2 1/4" drop I think will look sweet and have my feet planted nicely on the ground.
I am still getting used to riding again and know that I have yet to used to getting the sides of the bike as low as it could be in turns but, that is not the question now ( feel free to throw in 2 cents on that also ).

in my experience around 2 inches is were you start draging when you corner plus the bike will ride like a mule. but then it depends on how you have the bike set-up, your weight, 2up or not

you'll have fun gettin a jack under em:witsend:

This is most likely my favorite comment; "you will have fun experimenting with it!"
I ride by myself, not by choice, wife issue. I guess I can afford to have the shocks sitting around or resale the the lowering block if I decide not to use them. So for I like the big touring front end with a slight more rake and I think that maybe it crosses the lines on the freeway with less "wobble". I may have to put 2X6s under the tires to get off the jack with the next drop.
Ok, lowering shocks next in the rear and then decide how I feel about the handeling.
Croosh:witsend: , is how I describe the noise my old FXD used to make when it kissed the ground, never flipped me or made me loose traction.
