Jerky motion from going 1st to 2nd gear upshifting

[Mancitygoal]

Hi everyone. I have noticed when I am riding there are times when I go from 1st to 2nd gear up shifting that my real wheel does this jerk like motion , I have tried this in a control environment( parking lot) it works fine but when I am on the road its when it happens, what could I be doing wrong, am I up shifting at higher RPMs on the road, am I letting the clutch out to fast. My definition for the word Jerky is this( the backwheel sort of stopping for a half a  second like a burnout then going back to normal, as if something pulling you back then letting you go). It is driving me crazy, it draws my attention away from the road. Any tips are gladly welcomed.

You just need to relax and practice being smoother. You'll get smoother with practice. 

What's happening is you're not rev matching well enough and in the lower gears, i.e. 1st and 2nd, its way more pronounced due to mechanical advantage. If you are near the upper or lower extremes of the rev range in lower gears, <3000 or >8000 rpm, you'll notice this jerkiness more if you're not spot on and smooth with the rpm's and the controls. 

Try to keep the rpm when you start your shift closer to the rpm when you finish your shift. So you have to be smooth and deliberate when shifting, no hurky jerky, no pause for effect. So like start a shift at 5500, finish it at 5000ish kinda thing.

It's a long way (or at least always seems like it to me)  to  shift from 1st to 2nd  vs the other gear changes since is also has to skip through neutral.  If you're getting back on the throttle a little too soon (before the gears have fully engaged) what you're experiencing can happen. It's just something else to consider.

As @mossrider said it'll most likely go away with practice. 

Good Luck and stay safe out there.

Once you get smooth with the clutch, shifting quickly into second and letting off will help because the engine doesn't have much time to rev back down to idle.  It only gets part way, which is close to where 2nd gear wants to mesh anyway, then your letting off the clutch more quickly as well, making for a smooth transition.  Be careful while you practice that.  Once you get proficient, it's easy.

Get a 2WDW tune. Cured.

Thank you everyone, very helpful information Im enjoying my FZ07 very much.

I'll probably get trolled. LOL. But I only pull the clutch in to get started in first gear and to down shift. When you get good without the clutch it's smoother. It takes practice but now it's normal. I was taking my daughter for a ride and she even noticed how smooth the transition is through the gears.
