i've been meaning to post this for some time...
Has anyone using the 9:1 Malossi gears noticed that the bicycle engage button is very difficult to press in? Also that to disengage the button you have to manually turn the rear clutch?
I remove the plastic guard, and use a rubber mallet to engage the bicycle mode button.
Both my 12.25 : 1 stock gears and the Vespa 9.5 : 1 racing gears work just fine with the button...this problem is unique to the Malossi gears.
