In the meanwile I made a big tour with the R65, made 2000 km on the bike to france and it runs great....
I have solved the tachometer problem an other way because I got no responce from KOSO.
I got a new project a Kawasaki and the Tacho meter works wel on that bike..so I bought a new odo meter (small one with no tachometer) for the R65 and it looks great for me...
There was an question about my exhaust, I will make an other toppic of that...
