Why does my VESPA Scooter have excessive oil consumption and exhaust smoke?
- T
  Timothy MaloneAug 4, 2025
  Excessive oil consumption and exhaust smoke in your VESPA Scooter can stem from several issues: incorrect valve adjustment, which requires proper valve clearance adjustment; overheated valves, suggesting the need to remove the head and grind or replace the valves; misshapen or worn valve seats, indicating a head unit replacement; worn cylinder or piston rings, advising replacement of the piston cylinder assembly or piston rings; oil leaks from couplings or gaskets, necessitating a check and replacement of gaskets or restoration of the coupling seal; a worn valve oil guard, which means replacing the valve oil seal; or worn valve guides, potentially requiring a head unit replacement.

  Insufficient lubrication pressure in your VESPA Scooter can arise from several causes: a By-Pass that remains open, suggesting a check and possible replacement, along with careful cleaning of the By-Pass area; an oil pump with excessive clearance, indicating the need to perform dimensional checks on the oil pump components; an oil filter that is too dirty, advising replacement of the cartridge filter; or an oil level that is too low, requiring restoration to the correct level with the recommended oil type.

What to do if my VESPA Scooter has insufficient braking?
- B
  Brittney MorrisAug 16, 2025
  If your VESPA Scooter has insufficient braking, check the pad wear (minimum 1.5mm), inspect the brake discs for wear, scoring, or warping, ensure the correct fluid level in the pumps, and change the brake fluid if needed. Also, check for air in the circuits and bleed if necessary. Finally, verify that the front brake caliper moves in axis with the disc. Fluid leakage in the hydraulic braking system can also cause insufficient braking; in this case, replace any failing elastic fittings, plunger, or brake pump seals.

Why are the brakes overheating on my VESPA Scooter?
- G
  Gavin TaylorAug 22, 2025
  Brake overheating on your VESPA Scooter can be caused by a defective plunger sliding, which requires checking the caliper and replacing any damaged parts. Other potential causes include a brake disc that is slack or distorted, which can be resolved by checking the brake disc screws are locked and measuring the axial deviation of the disc. Clogged compensation holes on the pump can also lead to overheating, requiring careful cleaning and blasting with compressed air. Finally, swollen or stuck rubber gaskets should be replaced.

  If the clutch on your VESPA Scooter is grabbing or performing inadequately, check that there is no grease on the masses. Also, check that the clutch mass faying surface with the bell is mainly in the centre with equivalent characteristics on the three masses. Finally, ensure that the clutch housing is not scored or worn in an anomalous way.
