[QUOTE="timetraveller, post: 7815, member: 456"] I'm light man, I,m light, or do I mean Je suis ligere, mon ami? The question that arises from all this is why do some bikes suffer from this and others do not? Clearly some bikes have all bronze seats and some have hard inlets and bronze exhausts. Round here all the local Vin riders have had to replace their valve seats or do not use their bikes over significant distances. I would typically cruise at about 3,500 rpm with odd bursts above that for overtaking. Bill was about the same. I do not want anyone to incriminate themselves but I imagine that in France one is using about the same engine revs. So why the difference? I know that my diesel cars seem to go better on French and Spanish diesel than they do on supermarket diesel here. Could there be a difference between French and English unleaded? With the insular UK view it is generally assumed that French petrol is inferior to UK but really this dates back several decades. How about now? Do we have an expert in the club on the quality of various fuels and if so will they let the rest of us know what is happening? We are looking for facts now chaps, not opinions. :) [/QUOTE]
