Sounds interresing this, but for me it comes down to what the cost will be. Turns out noone here in Sweden does Nikasil treatment, they send th barrels to the UK or some other place in Europe. And sending this 9 or 10 kg lump back and forth won´t be cheap.....But then again nothing is, so....:(
Have a look https://www.revaltec.com/en/
they do it for iron bore , but no idea fro shipping cost.........
 
I would agree regarding the Taiwanese Hepolites. I put a set into a T150 a few years ago & as always I measured & weighed them first. They were all the same dia. to within 0.0002", all the same weight & also beautifully machined. The rings on the other hand were crap. The engine smoked badly so I fitted a set of rings from Norman Hyde, Goertze I think, & the smoking stopped.
I sold the bike to a friend & it is still running perfectly after many miles.

this has been found by others...change the rings for better quality before use!

as martyn said and in France some people use Goetze with a very good feedback ......sometimes ago B.Bogus said he had good experienvces from them and could give us any suppliers in UK.....
