Default New 18 & 21 on my 2009 Glide. somethings wrong!!!

So I finally completed my new wheels, tires, and fork springs. Went with 21 front, 18 rear, Progressive Drop In Kit springs, overall ride height is the same as stock. Bike is horrible!!!!!!!!!!!!! It feels like a snake at 65ish. I don't know what the deal is, very unnerving feeling!!! To me it almost felt like I was running 20 lbs pressure in the rear tire.

Rear 18x5.5 with 200/50 ZR18 Metzeler
Front 21x3.0? with 120/70-21 62V
Progressive Drop In Springs

Thats is, bike went from super stable to feeling like crap. The best way to describe the feeling is that it feels like a snake going down the road. It doesn't feel like my old RG that caught every groove in the road, still seems to go straight over grooves etc, just slithers down the road like a snake. Any suggestions?

since it is the same height, go back to the stock set up. those drop in kit springs are way too stiff. i had them in my softail and did the same thing.

Did the wheel switch on my 2009 street glide and left the suspension alone. Bike rides straight and true. No issues other then it leans a bit when on the stand.

I went with 21 and 18 combo as well on my 2009 Street Glide, BUT I went with the Progressive monotube cartridge lowering kit that lowered the front end a full inch and a half and it is perfect! You need to swap the front fork springs to the cartridge monotube spring kit that lowers the front forks and you should be fine.

I have the 21/18 setup on my 09 Glide and I used the HD lowering springs and it rides great, Im thinking that something isn't in alignment.

I have a 21 with ABS, don't think that really make any difference at all. My problem is the rear tire, new tire is on it's way!! I put the stock back on and it rides perfect!!!

I have a 21 & 17 (200 rear) with ABS and mine rides and handles great. I didn't lower it because it's fine for me. It's kind of hard to not have the rear aligned correctly because of the cam welded to the axle. Maybe the nut isn't torqued down correctly or a spacer is missing.

Why would it be the rear tire? What signs are pointing to your rear tire? By the way, what year is your bike?
