More info

Scootopia made Lambretta 185 barrel & piston kit. Well finally, it's here! Our 185 barrel kit has been faultlessly used and abused by our awesome race team in our endurance events, we have also had input and test development from Allstyles Scooters in Portsmouth. The kits used for the race team have been tuned by JB Tuning, the kit on sale here is not as tuned and is more of an around city/town kit with plenty of torque, this is not a kit that will give you the fastest scooter on the block.
The barrel is Aluminium and nikasil plated with an Aluminium head (there’s no need for a head gasket for the kit).
This kit is can be fitted to any Lambretta Series 1,2,3 OR DL/GP 125/150 & 175 engine case. We have developed it with the
Scootopia 22mm Carb  Scootopia GP150 Inlet Manifold and Scootopia 42mm Clubman Exhaust in mind (Standard GP Crank is advised but not essential). The kit also comes with High Tensile Cylinder Studs, Exhaust Studs, Inlet Studs, Nuts, Washers, Cylinder Spacer and Gaskets. For oil we reccommend Silkolene Classic 2 Running in, we suggest 300 miles (checking plug colour regularly) using an NGK B8ES Spark Plug.

Fitment help –

  •          Firstly, make sure you have your stud and gasket kit that comes with the barrel
  •          Install studs to barrel and replace cylinder studs
  •          Modify inlet and base gaskets if desired
  •          Install the inlet manifold
  •          Install piston with rings ensuring the arrow on the head of the piston points to the exhaust and that the rings are positioned to the piston ring pegs
  •          Add base gasket to case
  •          Carefully install barrel (we find rubbing a bit of 2 stroke around the piston and down the barrel will help)
  •          Install cylinder head using supplied cylinder nuts (torque down to 15-18 lbs)
