That is probably it.
I don't know very much about the bike because I just got it. I rode it about 200 miles before it gave up the ghost.
It is a 2009 gsa with 10 kmiles ..... so the previous owner did not ride very much at all.
What I do know is that on my 1150 gsa with 40 kmiles the injectors were clean.
Thank you very much for your replies.
