Hello ladies and gentleman, my first post here, been reading the forum for years. English is not my best language but i try my best. I have a question abaut first generation f800r, so here goes: when you turn the key, warning lights light up, everything comes to life, all is normal, but both needles twitch a little before you fire it up (maybe even when engine running, not sure)? The self test is fine, both needles go to full position and back. After that, when engine is running, if i rev it, also the speedometer needle goes up to like 20, 30 km/h. When i release the throttle to idle it comes back to 0. The RPM needle is ok, moving with engine RPM....but why the hell is speed needle moving if bike is stationary?? Fact is battery is old and weak, can that be the problem? Bike has both wheels on the ground, no centerstand. So basicaly why do needles twitch when you turn the key and why is speed needle going up when revving when the bike is not moving?
Thanks a lot for your answers.
