Changed all filters and plugs.

Any ideas please?

Check for vacuum leaks, especially the the main "Z" hose behind the TB assy.

Check the four rubber caps on the throttle bodies too.

Another common possibility for air leaks is the boots between the TBs and the cylinder head getting old and cracked. By now, they are 25 years old and have been through a lot of heat cycles.

A simple test is to take the LT left lower off and spray one of the following around the boots below the TBs: fine water mist, propane/butane, starter fluid.

If the idle decreases with the water mist or increases with a flammable product then that's where you issue is. They're not that hard to replace.

Disclaimer: IF you use something flammable use caution not to start a fire and have a fire extinguisher handy just in case. (That said, I've done it with starter fluid many, many times and never had an issue so there's no need to be paranoid about it, just cautious.)

Thank you for tips.
Clarification - I can get away if I give it lots of revs.
On easy throttle it stalls.

Checked contacts at coils - ok

Minor air leaks can temporarily seem to "cure" themselves as RPMs increase because

a) the volume of air leaked in is a smaller percentage of the total ariflow

b) the increased vacuum can close up the crack that is causing the leak

Just leave the second gear in and pull the clutch. As long as you pull the clutch in time, nothing stalls. If you are lazy, you can also start from the stand again in the second gear.

[Al.]

Don't get that.

Could it be caused by breather pipes connected to air box.
The little short one is covered in oil..

I notice now it's inclined to cut out whe I stop.
Haven't had time to seriously investigate.
Only driving around the road to test it
The pressure regulator is buried under the box too

Now I have acquired a gift of a Suzuki Burgman 650 so the
garage is kinda full.

Drove 120 miles on it today taking it home.

Decided to have a look this evening and run the engine.
Funny thing happened.
When I turned the handlebars to the right it cut out!!!!!

Check out wiring to ignition I guess.

I have read of others having switch wires with internal conductors broken where the loom flexes near the headstock.

If it cuts out when turning the bars, then have a look where the ignition switch loom is tie wrapped to the frame. The constant bending can cause internal fractures, but the insulation may still be intact.

Try to tug the wires apart one by one, sometimes that will be enough to see the broken one stretch.

Waggeled wires at thd bottom of the switch and it cut out.
Will I havd to take it out to fix wires.
I'd say it's broken at the switch.
New switch??????

You probably just need part 3 in this diagram
