I remember on my ninja and m2 you could speed shift without using the clutch, but I tired 1 time on the Xb12r and got the "clunk" effect. I guess this is due to the flywheel. So now I need to adjust my shifting for maximum performance. I notice if I do the standard pull in the clutch and shift method the bike slow getting up to higher RPMs. What kind of shifting do you recommend on the Xb12r. I'm starting to play around with coming on the gas a littler earlier before the clutch is let out all the way and that gives me a little jump.

Tatsu, I did some speed-shifting with my 12R and didn't get the clunk, well one time, I quickly figured out the right timing. Fell right into gear, no problem. I did it accidently one day then attempted it on purpose with no problems. I only did it a couple of times. It's not something I like to do. Anyone know what you need to do in order to reverse the shifting process, one up, four down?

Signguy.

Right now I'm on the street, but I am quickly warming up for a track day. There are two types of track days here. One is the circuit and the other is a 1/4 mile. The circuit appeals to me more, cause there seems to be more technique than the 1/4 mile. Not to offend those that run the 1/4 mile. I just like the ideal that at stock and given how short the course is, I might be able to hold my own. SouthernMarine I think you need a GP shifter or something reverses the shifting pattern. I need to read up more on this.

Do it all the time on the street on my SV, I also do it on my S3 but I have to get the timing just right or it will miss the shift. The SV is much more forgiving for this. The second to third upshift is tricky on the S3

The VROD "speedshifts" better than any of the other Harley/Buells I have ridden, XB's included.

Just put your boot under the shifter, put a little pressure on it, quickly go off and on the gas and up to the next gear it goes, repeat as necessary. It works best at the upper rpms.

The blipping on downshifting is the thing that still gives me fits at track day speeds.

Changing the shifter to 1 up 4 down is a small 5 min operation.
Remove allen bolt from top of linkage adjuster bar and let bar and pedal hang loose, remove allen bolt from spline linkage. Carefully pull off spline linkage and rotate anti-clockwise approx 190-200 degrees and replace. attach linkage bar to spline linkage and check operation, removing and realigning spline linkage if needed. use adjustment on bar for smaller adjustments. Finally retighten the 2 allen bolts.
See pics below.

Standard (ish)
Before
1up4 down
After

Wow that's sweet Beast! What the advantage of reversing the shifting, besides really messing you up the first few times out?

I frequently skip the clutch when running hard through the gears on my 9. It is much quicker and smoother. I never have a problem as long as I am over 4500 rpm and blip the throttle slightly. There was a pretty good article in last month's Sport Rider about that very topic.

Keep throttle WFO And IN ONE QUICK MOTION!
pull in clutch the same time you are shifting up and just at the same time you foot makes an upward motion relase the clutch.
; )
It makes for some intresting straight line runs!

If it works??
you should be ok as long as you adjust it correctly, make sure the foot lever doesnt come into contact with the primary at its extremes.

Been riding round like this for weeks now had no problems.

Have a couple of old velocettes 1 up 4 down shifting so my buell aint the "odd" one out no more.

Okay, but can someone tell me the advantage to 1 up 4 down as opposed to stock.

That's the whole point, you don't HAVE TO USE THE CLUTCH at all, just do everything spidy just mentioned but FORGET about the clutch. Don't even look at it.

When you put some slight upward pressure on the shifter, just a slight unloading of the driveline by going off/on throttle quickly is enough to get it to the next gear, no clutch necessary.

The latest Sport Rider, as mentioned, has a good how to article on this topic.

If you have to upshift while leaned over hard left, the GP pattern helps. It's also easier/quicker to stomp an upshift. Downshifting you usually have plenty of time to get the toe under the shift lever. Stomping down on the lever when speed shifting works very well for me. I'm not shifting at much below redline though. Might not work too well if you try it much sooner. Chop the throttle off/WFO and downshift simultaneously.

The advantage of "GP" shifting is that its faster/easier to push down on the shifter than to pull it up to upshift, particularly in road racing.

Let's say you're hanging off the left side of the bike, and if you would have to get your foot UNDER the shifter while hanging off the left side of the bike while exiting/accelerating out of a turn at race track speeds, while the other rider who only has to TAP DOWN to upshift while hanging off the bike coming out of the turn and accelerating will have an advantage because he does not have to keep his foot under the shifter.

Blake got me by a few minutes.

Okay..thanks for the explanation. How long did it take you guys to get use to the reverse shift pattern?

I've been working on an up-shifting technique I was introduced to at Jason Pridmore's STAR School; 1) on the gas 2) put pressure on the shifter (up for standard shift pattern) 3) feather the clutch which will unload the tranny gears enough that you upshift 4) keep pressure on the shifter until you know you're safely in the next gear up.

When I get it right it works really well for me, and is a very smooth way of shifting.

Took me a long time. The std pattern is still ingrained into my subconscious.

I'll tell you one thing surprising though, the GP pattern is no good for drag racing. Upon launching it's more difficult to push down to up-shift without upsetting the bike.
