I've done the above, works a treat

Bonus - any pics for people who reckon electrickery is the work of the archdaemons of Ohmland!

These may help. Direct alternator wires to reg/rec plug, and new negative and positive wires to battery from reg/rec.

Piece of cake if you have patience, a good soldering iron and a wire/spade cutter/crimper

Maximization of the efficiency of the thermal connection between any rect/reg and its chassis mounting surface will extend its life, particularly the older SCR type that tend to run hotter than the newer FET type. Rect/reg size and number of fins are not necessarily an indication of superior perfomance.

Still curious as to what an earthing kit is?

I do agree, however the R6 shunt-type units have deep cooling fins on both sides, meaning that very little heat can be shed through the subframe. The extra cooling capacity of the fins (must be 300% more surface area compared to Honda unit?) probably really helps them.

Jo: Magg makes a good point, if you need to replace the reg/rec (again!) go for a newer MOSFET type, they're more reliable and efficient than the traditional type. They wire up differently but it's not hard.

I suspect that the finned all over rect/reg is a FET shunt type and therefore runs cooler, hence no flat surface considered necessary for extracting heat to the chassis.

Older type can be reliable just need to take care with mounting, flat surfaces and thermal transfer compound to maintain good heat flow.

Any news on what a earthing kit is.

Rick O provides (4?) handy leads which can be used to improve the bike's earthing points (between battery -ve and frame, coil etc).

It's only going to help if the existing earths are insufficient, though at 20+ years old and a questionable electrical system from the factory some have found that it helped their issues.

Cammo, none of the recommendations in the links IMHO have a sound engineering basis.

Wires added between ignition coils and chassis serve no purpose.

Any added between engine and frame would be equally ineffectual, unless all the engine mounting points are non-existent. Similar comments apply for wire added between stater motor and chassis.

Unmodified OEM wiring loom integrity should be ok no matter what the age, poor earths can/will cause electrical system problems. OEM design deficiencies can cause less than ideal battery charging and headlight performance but these issuses will not be remedied by adding a few earthe wires.
