Jerky Throttle Response

Hey everyone!

Is anyone else throttle on/off jerky?

For me it’s really bad at low rev ranges and low gears, but still noticeable at higher rev ranges and higher gears.

Is there a way I can smooth this out? It’s nearly bucked me off in a couple corners now

Cheers
Josh

That doesn't sound normal. Could your chain be so loose that you have too much backlash between the transmission and the rear wheel. In theory, that could cause the effect you describe.

Thanks I’ll take a look and report back.

Looks ok to me, within the 2cm each way

I’m wondering if it’s the throttle position sensor?

2 cm up and 2 cm down? That is
4 cm total. It is too loose. Total should be 2.5 cm - 3 cm.

Hi! I'm having the same issue. Seemed like it was at the same time as I changed my brake and clutch leavers. I did however check my chain and it's adjusted correctly.

Did you find out what was wrong with your bike?

I am having the same issue. I only have a little over 1000miles on mine and for a while thought it was just my wrist twisting the throttle too much in either direction. But starting a couple days ago the engine died. Then on my way to work today it died again. It will restart but it's more than a little unsettling to have the engine die in the middle of rush hour traffic. I'm taking it to the dealer after work. It does not replicate easily so I am hoping there is an engine code or something the mechanic can pull from the computer(s).
