found some bigjim info on clutchless shifting but majority of info was for racing bikes and even they get there trannies rebuilt read below:

BTW the 5 spd can be easily driven without a clutch, just that you have to shut off the engine to get into gear when stopped. Shifting is simple, run each gear to 3k and then apply pressure to the shifter to pull it out of gear, then let off the gas, when its ready it'll pop right out of gear, then give the engine a good rev and apply pressure to the shifter to push into the next gear, it'll go right in like you used the clutch.

Although I'm sure this comment will make Terry cringe, clutchless shifting is even easier than you described. Done properly it can be nearly as smooth as when using a clutch. As you let off the throttle, pull the shifter into neutral. The shifter will pop right out as you remove the engine load. If you are upshifting, as soon as the shifter is in neutral, apply gentle pressure toward the next gear and as the engine speed drops to match the correct road speed, the shifter will slide right in. When down shifting, you must gently rev the engine to get the engine speed to match the road speed needed for the shift. The key is that the two rotating elements in the trans that you want to engage must match speed. If they do, they will slide together easily. If they don't, the slight pressure you are applying to the shifter handle will not be enough to allow the shifter handle to move. Once you know how, it is nearly as easy as using a clutch.
Since the consequences are disasterous if you mess up, I'm not sure that I would recommend doing this unless you have someone show you how.
By the way, a large share of 18 wheel drivers seldom if ever use a clutch. Because of the very low gearing even the slightest movement is usually enough to engage a gear without a clutch even from a dead stop.
Clutchless shifting is a nice thing to know in case of an emergency, but otherwise is is really nothing more than just a parlor trick.

Re: This gear thing is getting to me! PLEASE READ

i have a 2000 svt and i love the way it shifts if im traveling real slow (rush hour traffic) i fell the lurch your talking about but to me its no bad enough to warrent any change.... when moving all gears seem to just fall into place i mean to me there perfectly spaced and the clutch just works
either way if its really a bother to you try some of the fixes here or see if ford could help but to me its really not that big a deal
and about the clutchless shifting its actually quite easy and i do ocasionally in the svt (normally as im coasting to a stop slowly accelerating from my home)
To a stop: just pull it out of gear pull it towards the next gear blip the throttle and it will pop right in gear no grinding or anything
Accelerating: speed up pull it out of gear pull it towards the next gear wait a moment and it should pop right into place as you drive
now of course this is a personal driving method i dont recommend it to anyone i personally just use when im being lazy or if my left foot is comfortable as is.
Clutchless Shifting
Mastering the art of "Clutchless Shifting"!
One of our secrets as bike racers is "clutchless shifting". You can
actually shift gears up even without using the clutch. This will
enable you to shift rapidly on hard acceleration so that you can
jump ahead of everybody. You may notice that racers shift in rapid
succession in a race. Pulling the clutch simply slows down the engine
RPM in between shifts, losing you precious RPMs.
Here is how you do it: Pull away normally from a complete stop
using the clutch. Accelerate with a full twist on the throttle,
and apply a little bit of pressure on the shift lever. Quickly flick
the throttle to off and JAM THE SHIFT LEVER UP and twist to full
throttle again. The gears will engage because of the momentary
relaxation of the transmission from flicking the throttle to off.
Gears will engage even if you don't engage the clutch! Do this
on every succeeding gear, like a GP rider! For sure the bike will
accelerate hard and jump at every gear change.
Dear MMSC,I just got a brand new Honda CBR 600 F4i a week ago. I am still at break-in period. I have a question regarding gear shifting techniques. When I rode my previous bike, I used to using clutchless gear shifting technique to shift up gear and it went smooth. Except the 1st gear, from 2nd to 6th gear I always engage the gear at certain rpm w/o pull in clutch lever. However, since this is a brand new bike and need some break-in process, I was wondering am I allowed to use that technique as well during this break-in period. If I use clutch each time when I shift gear, I hear some click sound on each gear shifting. And sometime it did not go as smooth as I engage gear w/o pull in the clutch lever. Can you tell me why does that happen? If I use that technique on new bike break-in period would that damage the transmission or engine at all? Also, to keep bike operate smooth and last longer, what is the best or appropriate methods to break-in new engine. Thank you very much for your help. I appreciated in advance for your professional response.CurtisAnswer #1Use the clutch. That's why the manufacturer put it there. Pauline FraslAnswer #2Smooth, skilled throttle and shifting needs very little action from the clutch. However, remember that racers (who shift without it all the time) also rebuild their engines between races! I personally would put as little stress on the drivetrain as possible during break-in: use the clutch, especially during that time. The CBR is nearly bulletproof, but you still want to make it last as long as possible.There are several different "takes" on breaking in an engine properly. For warranty's sake, I advise you to stick with the manufacturer's recommendation. However, I have heard that running the engine GENTLY up to redline (no load) several times in the first 600 miles or so is another method, and it has its merits, according to an engineer friend of mine. (In 1st and 2nd gears, roll the throttle very slowly all the way through the rpm range until the red line.) I'm not advising this, it's just something I heard. I also came across this just yesterday:

You need to look up and read about "constant mesh" transmissions. One of the great things about motorcycle transmissions is that they'll shift quite nicely without the use of the clutch – at least the good ones will. The gears are always meshed and are locked or unlocked from the shafts by sliding dogs -- this is best accomplished (for most people) byusing the clutch to cause a "break" in the power delivery to allow for unlocking one and locking the next. And, really good transmissions will do it without the "break" in power flow -- but there's risk involved. So, to answer you question, "depends" -- depends on the bike (how good the gearbox was designed), your skill level, and how much you want to risk the performance / longevity tradeoff. As for break-in, it's almost a non-issue nowadays. Most new bikes need only a short period of normal use (see the manual) to be ready for anything – especially anything you should be doing legally on the street.John Atkins -- MMSC Instructor
