hang on...what about the reason why, you were a bit over anxious that you didnt get an immediate answer doring a working day? cant you see what Drewpy meant?
I'll say it again, nobody knows the answer or you would have got one...that is no reason to put up posts like'????????'...an obvious sign if impatience and frustration and it's un-called for. Its a modern bike and there is no expert posting here often about this bike, if you learn something perhaps you fill that space
You say you expect help after all the help you have given...you only made 9 posts FFS, you tell Cynic to get off your thread...let me tell you that Guy has helped hundreds of people but doesnt suffer fools for long
I can tell you a member here is is very up to speed with these bikes, a German member goes by the name X FISH
