Hey guys,

I just picked up a booster 90. The previous owner said it was recently serviced back in Germony and has 0 hours on it.

I went to start it yesterday and it's acting a bit strange. When I connect power the micro GSU says " Jetronic VX .4.12" It then starts flashing "Jetronic VX 2009" and that's it....

I can can enter the setup menu and did the throttle programing but the main screen is just the flashing Jetronic 2009 screen.

if I disconnect the battery and wait a little bit and re connect I get a memory error and it says to hit set button to reset. I the. Loose all the throttle settings..

Does anyone have any expierence with this??
