Evaporust breaks the chemical bond between iron and oxygen, it doesn’t turn the metal black or any other colour... The only thing you must do is rinse thoroughly with water and then (for tanks) immediately dry and slosh some 2t and petrol in there to prevent flash rusting, which will occur whatever technique you use if you leave untreated after rinsing.

Electrolyte works well but can be fiddly fashioning an electrode and an insulator, currently being discussed on another thread... Recently i have used “evaporust” to good effect. Pro’s its re-usable and can be used on any ferrous items.. con’s its a bit expensive at 30 odd quid for 5 litres.... magic stuff though, not acidic at all....works by breaking the iron - oxygen bond, clever stuff.

Yep.... i left mine overnight, although i must admit i was a bit nervous of leaving it... The amount of crap and rust that came off was amazing though..

I have used this technique in the past with great success... But watch out, last time I mentioned it on here i had one of the resident “experts” telling me it didn’t work... even though it did 😄

Sye... whilst power divided by volts indeed gives amps it’s not the full story when resistance is then bought into the equation. Your post fails to explain why lamps brighten as you increase the voltage - which you’ll know from 1st hand experience. The current (A) actually increases as you increase the voltage through the filament...the power rating of a lamp will be only be valid at the stated voltage .
Anyways, please don’t take my word on it, but rather google the explanation.
Yea, Deltarider, horses for courses. I’m gonna take a punt on the LED headlamp bulb, and will report back in due course. They annoyingly come in pairs... so if fail early I’ll have a spare 😂.
Trig... you say you’ve got LED replacement ‘globes’.... how are they performing?
I have had the cob type fitted to a 750 and a 550 for about a year or so and the 750 is just over a couple of thousand miles, since fitted with no problems. They are white light and not the yellow light you get from basic H4's.
I bought a trade pack of them and they worked out around £3 per bulb. I am no expert when it comes to electrics and can't understand why some of them have a cooling fan (which will not fit in the headlight bowl) and the cob type don't.

I bought some of these bulbs by following the link that trigger posted.... that particular item was sold out but i did manage to find an exact same item for something like £1.98 each iirc. So i bought 3. They were due to arrive in mid sept but actually turned up in about 3 or 4 days, so i fitted them yesterday and they work and look great. I put one in each of the yamaha’s but kept the third as a spare since it wont fit in the Honda as it is still running the original sealed beam type unit and i would need to buy a replacement shell to fit it... prefer to keep her original if i can.. But if and when it ever fails i will definitely go with the leds.. at 6 quid for 3 bulbs its a no-brainer!

He does say “not a rebuild or restoration” and then goes on to list the extensive restored and new parts …

550 looks nice, especially with that delkevic pipe, the new owner will be well chuffed

Some interesting links there trigger and lobo. I will certainly give the led bulbs a try.. The reason i said “they’re expensive” is because i have tried cheap led’s before (although not that type) in the car i used about 6 bulbs in the rear lighting, 3 of them failed within a day so i took them out and wrote the idea off...but at the time i did notice that branded equivalents were much more expensive. I will try the bulbs in triggers link..on the CB and RD250 which is especially poor with a std bulb.. cheers.

Has anybody fitted led bulbs to their sohc bikes, i don’t mean replacement light fittings, I mean replacement led bulbs in the original fittings.... I believe they are available, they are expensive but will definitely look good and give the charging system an easy ride... If anybody has I would be interested to know which bulbs and where from.

Had a run over to the inlaws caravan on Spurn Head yesterday. I intended to video the run back but forgot to turn my camera on when I set off, i realised this and pulled over in Skeffling to turn it on... Then my battery ran out just as I was leaving Hull... here’s the movie, nothing too exciting I’m afraid... a steady two-up ride https://youtu.be/KPWb8Xvh4po

A nice looking survivor...I do like to see honest unrestored bikes. As has been mentioned recently on a few threads, you could try reversing the coils so that the leads exit from the rear and thus get less wet in the rain. Failing that I would imagine that a replacement set would probably sort the problem...
