Clutchless upshifting
 
Followed a piece of advice I was given in "how many fingers" of how to change up gears without the clutch.*
Really liked it.
Did everyone else already know about this? What else am I missing out on? What other priceless gems of advice do you know?

Oh, and will this damage my bike?

*Put upwards pressure on the gear lever and ease of the throttle** - it just slips into the next gear. **Only works when you're accelerating

Works going down the box as well, but not for novices ;)

I won't be doing that then....
Maybe someone can loan me a bike to try it on :wink:

Most racers use clutchless upshifts. The key is to match the revs to the gear your in before you change up. IE riding along fairly briskly if you want to shift up do so at the higher end of the revs otherwise it can be hard to get the gear to engage which can then harm the gears. Just back off the throttle a tad and knock it in then accelerate..

Doing clutchless downshifts isnt recommended as this can harm the gears. Being a v-twin it is best to use the clutch as this will also help if you then realise that you have gone down one gear too many as you can slip the clutch manually!... :shock:

Stu, I'm in the same boat. Read the same bit of advice & figured I'd try it.

Seems like it only works above 6k rpm on mine, and 6th didn't like it at first. Having said that, the gearbox is new, I've only done just short of 900miles, so that could account for it.

In response to the "fingers" thread, my answer is now "3 when going down ;) otherwise, what's the clutch do exactly? (2 on the brakes)"

Also, I've started to get the hang of the front brake hill starts :) Wouldn't recommend it on a big hill, but it doesn't take as much movement on the throttle as I thought.

What's the big problem with rear brake hill starts?

Yep.

I usually use the slipping the clutch method anyways rather than the bleeping method and has save me a couple of times. You can just about feel it as you are letting it out and all you have to is hold station or pull in a wee bit while still retaining drive.

Thanks for the 'professional' view.

The hendon shuffle. But no seriously, I've only done it a few times (front brake), and pretty much accidentally did it this morning when I set off. The road was more of a flat than a hill, but let the brakes off & it still rolls backwards. Was shocked I'd done it without even thinking about it :shock:

(I then may or may not of hit around the 8k rpm mark to wake up my future in-laws neighbours on their quiet little suburb estate :evil: )

I wouldn't do it in the lower gears. All feels a bit to mechanically unsympathetic (sp) to me
