The current software is becoming a real pain in the behind and there are some manuals that will not download. If that happens, send me a message and I will send you a direct link. Please do report WHICH manual can't be downloaded, preferably with a link.
In the meantime I'm going to make a planning for next winter to change and upgrade parts of the website. It'll be a helluvalot of work, so please have patience.
And I also will have a small holiday and will acquire a new motorbike at some point... :D
