Vespa Maintenance Guide


Having a good tool set is essential to fixing your bike with minimum effort. I have outlined a few of the essential tools; there are others that you will need as you repair the engine. I will post these tools used when i get around to rebuilding my engine. These basic sets will help you tackle most frame, headset, electical, wheel and carburettor problems. A torque wrench is not essential, but it will save you having to break out the helicoil set to re-thread your engine case. As a rule of thumb, if you dont KNOW the torque, tighten the fasteners until they are SNUG or until the lock washer is flat, overtightening aluminum is really risky, less is more in this circumstance.
