Ooops....Thank's for pointing that out.
Clearly I didn't understand. :oops:
Is it too late to claim undiagnosed dyslexia????

I happen to be a driving god! NOT
How would one go about getting that 20% more chav added to one's score?

That's the downside of written language. Look at it one way and it can mean one thing, look at it another and means something else, read it too fast in the wrong mood and it can get the blood boiling...

Today on my little journey out i thought about blipping the throttle, did it a couple of times and if im honest, it just doesnt feel right, either that or im absoulty s**t at it and cant do it properly, so i dont think ill not bother and just carry on as i am :p

yeah if you get it wrong it can upset things - upset the suspension, snatch the chain, etc.

I'd recommend, if you still want to give it a go, to wait for some better weather. Stick with what works for you at the moment.

I do it all the time (and not for the noise).

It took me many attempts to get ok at it, do it now without thinking, not all the time tbh but most.
I found for me it stopped being thrown forward a bit with me feeding the clutch out on downshifts and not matching the gears to revs etc

Don't think i've ever done this before so thought i'd try it on the way to work this morning.
First couple of times that i remembered to do it was neither here nor there but one time i got it bang on and it sounded superb...after that i could not hit it again - even on the way home - and it just messed up my braking distances, made the ride much more jerky and took most of the enjoyment out of the ride.
I should add that I was also trying out two fingered braking for the first time today as for the last two years of riding a Bandit and now an SV i have been grabbing a handful of front brake and not known any different. But i don't believe that had much to do with the "blipping" problems though as i seemed to get on ok with the two fingered braking on its own.

It's just how to ride the SV.


Ditto,

But for any bike. 2nd nature now

Always been a blipper.

I rev match too!! ;)

i have been meaning to learn to do it properly as i feel it would help smooth downshifts just waiting for better road conditions to try new things on.

The dog teeth just go together much more smoothly when they're rotating at a similar speed rather than several hundred (or thousand) rpm apart.

I learnt to do it when learning to drive a car. It's just smoother and easier on all the internal components - I think it's known as 'mechanical sympathy'. Believe the technique itself dates from gearboxes without syncromesh, when you had to double-clutch and rev-match on each change - or it simply wouldn't go in. I used to have a '72 Triumph Spitfire as a weekend car, and that had no synchro on 1st gear - so you had to double-clutch and rev-match when you went down into 1st.

Great theory, and I agree with the notion of "mechanical sympathy"... but unfortunately the crash box theory doesn't quite work for meshing gear (dogs) in an MC gearbox because of the nature of the selector drum mechanism. As soon as a gear is disengaged the next gear is being engaged and the neutral period is in the fractions of a second and no control is available to the user. A blip during this neutral period isn't going to do much even if the clutch could be effectively timed.

Blipping shouldn't make the slightest bit of difference to gear engagement. The only area where it does make a difference is on the clutch release, by ensuring that the engine speed is a reasonable match for the gear and road speed eliminating most of the need to use the back wheel to accelerate the engine, the associated jerk or clutch slipping, and reducing the imact as the drivetrain backlash takes up.
Even with a synchro box a cage will benefit from a blip on the downshift just prior to clutch engagement, but it is not the same as double de-clutching a crash box.
