750's don't vibrate.....much

My GTF just vibrates backwards on the centre stand whilst off the bike gently revving the throttel , good for accurate parking 😊
 
Problem solved. 2 leds for $8 free delivery. Don't tell tom, I think they're made in china.....

"gently"?
Mine aggressively bounces and makes tracks in the concrete with the centre stand, I try only to start it when off the stand with me sitting on it to keep it under control with my mass on the seat and the front brake to stop it moving. Perhaps the balance factor is very different between the SF and the GTF motors?

The GT crank is heavier ..... presume GTF is same. Also the variations between bikes is quite extreme. My first SF I owned in the early 80's would move sideways quite quickly when on the stand. Near identical model I have now hardly moves at all.

My GT doesn’t vibrate at tickover or leap around, I remember strobing a Norton Commando and it ran off! I think the round mudguards on the S/SF models aren’t as rigid as the squared type will vibrate more- this may contribute to tail bulb failure, mines been in since at least 1986.
I also Set the tickover so the engines all running in one direction - 490rpm tickover is going to shake the snot out it .
 
my (bought new) SF1 didnt move around on the stand for the first few years of ownership, and it would also only idle for a few seconds at red lights (maybe 20) and then die, every single time bar none, unless I blipped, which I of course did, then I learned that balanacing the carbs with instrumentation was highly desirable, so equipped myself with a set of four gauges, and balanced away, I had to use a rope around the forks, tied to a bench leg, to stop the bike walking backwards and maybe damaging the rear end on the wall, but OH BOY! had I missed out on a smooth and willing motor before I did this, it was very different, would rev off the clock and tickover for decades. I even reduced the rear sprocket by one tooth (39)
