Good evening. I'm Alan from South Yorkshire and have several GT550s and a Kettle.
Lots of experience on here and other places, but we like a bit of intro and history first.
Think of how stupid the average person is, then realise that half of them are more stupid than that.

Drain oil, pop clutch side cover and take the clutch plates out, clean them , oil them and reassemble. That's it.

Moisture got in there plates are corroded a little. Not hard to do but no other way I know to get clutch free and working on all disks. Expect that you will need a new clutch cover gasket. Oh, get a good Phillips impact driver for it's best to loosen the Phillips screws for their heads strip easy. Male sure you use the larger Phillips head bit (#3?). You may get a way with brand new sharp hand driver but again it's the larger Phillips head and if too small you definitely strip them. Push in and give a quick twist to loosen.

What do you mean getting a little tingle from plug? Is was not sparking so you had the kahonas to grab the plug electrode to see if you would get a zap!

Good batt. good points, proper gap, condenser, good wires cap, coil and plugs you should get quite a jolt!

There is a slight difference between JIS & phillips screws. All of the original screws on your bike are JIS. Its why so many screw heads are messed up on these old bikes. JIS screwdrivers & impact bits are worth every penny if you are going to do much work on these bikes.

Vessel Megadora screwdrivers & a Vessel impact driver are good choices.
You can get them via eBay. Hopefully one of the UK members will provide some other choices.

+1 Everything Vintageman said on the clutch plates and +1 everything Jabcb said on the JIS screws. The JIS screw thing is something I learned about 5 years ago...and wished I'd known the previous 40! Good luck
