Sven....... My comments were not to you.
Your bike is exhibiting symptoms of running rich. The thing that normally
associated with an overly rich mixture is deteriorating performance with an
increase in engine temperature. Perhaps the situation will present itself
when you can ride the bike under hot conditions and park it until you have
time to pull the spark plugs and inspect them. If they are dark.... at least
you know what you are looking for. Being injected complicates the issue of
proper mixture because by design it is supposed to be self adjusting.
