Thanks for the opinions JNS. This was really getting to me after I put on the mids. Although everything is connected to the fairing stay, I can push it back and see how it will look. The fairing stay is held up with 4 brackets which can still be modified or redone. I can drill a bigger hole in the bottom brackets and try to drop the bottom of the stay to see if it changes.

About the mids and lowers, look at where the mids of the 1k end, it covers till where the clutch line starts at the clutch cover. Also where the mids start is where the lowers will meet, I think its gonna cover the front tire too much don't you think? I think it will definitely need a pull back, about 2 inches. I am still waiting on the windscreen though, and I will get a better view of where its gonna sit. Thanks for the help guys.

I took this picture right now of how far the mids are from the frame just so you get an idea. On the 1krr the mids are flush with the frame/tank, ofcourse I dont have a 1krr frame but I dont think the angles are very different.

Actually, what I'm saying, is that in my opinion, how far "forward" you've got them mounted, looks pretty spot on - if you look at those photos for comparison, it seems that the distance between the forks/levers to the upper fairing, is very much the same on your bike, as it is on the 1000RR, the only thing I noticed that might be off is the angle, which like you said, could be adjusted a little... not seeing the brackets you made, I can't really advise how I would do it, but if what you made is what I envision, just slotting a couple of the holes would allow you to "tilt" them, so to speak.

Regarding the tire coverage, if you look at the 1000RR, there is some tire coverage; the reason it seem like yours will cover so much of the tire, is due to the change in rake, from your forks being so high in the triples - I think if they were set closer to standard front ride height, it would be very similiar to the 1000RR.

Honestly, if I were you, I would try to get the bike's geometry back to stock, or at least closer to it, by dropping the forks in the triples and removing any lowering link in the rear, but that's just me. With it sitting that low, and with stock shock springs (very soft) and stock 5W oil, you run the risk of smacking your fender on your rad if you get them near bottomed out. Also, when you get those lowers on, they are going to be perilously close to the ground!
If you do keep it that way, I would definitely go with stiffer springs and/or heavier fork oil.

Now how you ride, and how you want it to look, is all that really matters, I'm just giving you something to think about, besides, for all I know, you're only 5' 3", and really need it that low!

Anyhoo, if you do decide to make any changes in ride height, now is the time, before the fairing work is done!

Actually the angles are more different than you might think - the RR's upper beam arcs back in toward the steering head much sooner than the F2, but it's fine, you'll be able to make that work.

Bear in mind, that tab the fairing is touching in your last picture, is for mounting the OEM F2 uppers at the rear - if you are 100% certain you are never going back to stock plastics, you could cut that off with a Dremel, and touch-up the paint, that might allow the fairing to be a bit more flush.

Wow you definitely solved this problem JNS! I never realized that the pictures for the 1krrs I've been looking at are at stock height. I guess I will just slot the whole for the bottom brackets where the fairing stay mounts so that I can run it more back from the bottom only!?!? Correct? I guess I can look at how it turns out from there.

By the way I'm 5'7”, but something about lowered bikes calls for my attention. It might not be an excus but there are no twisties around here. I use this bike to get me to work or a cruise with the wife. I have daily riden an 06 600rr and I didnt like it either, I have to tip toe or lean one side in every red light and thats not too comfortable, then you say why do you have an f2 right, well I love the seating position on these. The 600rr rearsets are higher in position, meaning your in an uncomfortable position. I love my f2, but shes just a show stopper, with no chrome.

Also on another note, I've been thinking how I'm gonna cover the infamous subframe, the part that always shows in every conversion. I was think about getting the side tank panels from a 600rr, why the 600rr, becuase the 1krrs side tank panels are integrated to the tank shell and the 600rr's are not. Take a look and let me know, I think I'll make them work to cover atleast something.

The 600rr side tank panels, the black ones.

The 1krr tank shell. As you can see its also red and is integrated to the shell.

Yeah, that is the main gotcha" with the tail swap, which is why when I get around to that on my street bike, I'll be using an '03-'04 vintage 600RR tail, so there's less "uncovered", though, if you get those additional panels, either one will work.

That said, I'm not going to be mounting the plastic, but rather cutting off my subrame, and welding new mounts for the entire rear-end assembly from that year/model, so there won't be an issue anyway - it's more involved, but that's the route I'm going.
Even with some of the newer models, there are bits of the subframe showing, like on the F4i, but I like the more "clean" look, with all of the subframe hidden.

Once I've ironed out the process on the street bike, I'll be doing the same to the race bike... it'll be in the future, though, too much to do before this racing season!

I would have to agree that cutting the subframe and welding a new one ia the way to go. Though I dont think I have the welding skill to weld on a new one to my frame. Thats why I went this route instead.

On the lowered topic, I found this 600rr with a before and after picture of the drop. The front tire is pretty tucked.
