Throttle Sticking?

Hi all, just jumped on my bike to head home after work today and got to the traffic lights and realised that my throttle is sticking solid. I have to physically turn the throttle off or it will just stay where it is. Is this an easy fix i can do myself or should i take this to my mechanic? I'm just a bit timid on doing things to the F4 myself after my last little incident haha

I would suggest take it to a mechanic. It must be the wire running all the way down to the butterflies.
A friend of mine thought he could fix it and while on a ride his throttle grip got stuck at 260km/hr. He spent 4 months in the hospital. These kind of things (safety related) I always say take them to the mechanic

before you go to the mechanic try loosening the bar end via the Allen bolt. Over tightening causes the bar end to push against the rubber grip and therefore throttle gets stuck

I had exactly what Adam suggested. It just started sticking one day and I'd never adjusted anything. It was only after I'd disassembled the whole throttle control assembly, found nothing and reassembled it that I found that as soon as I put the bar end in it would stick again.

I had a similar sticking throttle problem on my 748 once which would only happen when the bike was hot, and that was that the butterflies were sticking open in the throttle bodies and I had to loosen them on their spindles and re-centre them. (That was a scary one actually as the first time they stuck open I was approaching a corner and desperately trying to slow down..)

Had the same throttle problem. A slight turn of the Allen bolt on the bar end fixed it immediately.

losing weight

me i'd move the throttle inboard a mm or so to avoid the issue entirely......
then again i don't like bar end weights any way, so i just use plugs

i had a handlebar go through the back of my leathers and the liner, if the angle was a little steeper i wouldn't be typing this.....so i never go without bar plugs....as for the 'vibration' never paid attention to it....want my weights?
