I have been fettling the GS in an attempt to improve the running[1]
since I put the K&N filter on and have a little issue with the engine
not slowing down very quickly when I close the throttle. I am fairly
confident it is probably running a bit lean but could this be the cause
of it? If not then what, the sliders seem free enough.



[1 ]Finding out one of the coils was a bit iffy certainly helped the
poor starting issues.

If the slides are free then it's definitely mixture - lean running
usually causes the revs to rise (eg if you leave it on tickover with the
fuel tap switched off, if fitted, the revs will rise before it conks out.)

Isn't that the sign of an over-rich mixture?

Which is almost certainly not standard. That much I am sure of.

The LHS particularly had been well ****ed about with before I got the
bike and most of what I have done since has been putting it right rather
than trying to improve performance.

The only thing I am not too sure about is the head on the fuel supply
and how much difference it would make. My temporary rig is gaffer taped
to the bars and so is a foot or so higher than with a tank on, which
would tend to make it rich.

I just want to make sure it is as right as I can get it before I commit
to putting the tank back on. It is far too much faffing around to be
taking that on and off a dozen more times for bugger all improvement.

And air cooled engines don't like running for too long while you play
either so it is short bursts of annoying the neighbours and many tea
breaks, which don't help. Colostomy bags don't come cheap.

One was but has been retired. The three I have left are all fine as far
as I can see.

The throttle cable is sticking.

I don't think so but it is only single cable operation so I cannot be
sure. It is just like a sticky slider but it ain't that, which is why I
am asking if extreme mixture could be the issue.

If your float valves are working OK, it shouldn't make any difference (for
all reasonable values of head of fluid). Until the fluid pressure is enough
to overcome the float valves, the float level will be unaffected. It's not
a linear thing.
