In the world of scooter tuning today there's a wide selection of tuning parts available. This may leave you a little confused when choosing the right parts to make your scooter more useable. So, we've put together a few suggestions for parts that can be used reliably if you use your scooter daily on the road
PEUGEOT VERTICAL AIR COOLED ENGINES
For two-stroke Peugeot vertical air cooled engined scooters like the Peugeot Speedfight, Trekker, Vivacity etc. the tuning process should be approached slightly differently due to the engines being a bit awkward to set up.
Cylinder kits: The Polini cast iron 70cc kit gives good bottom end power and will work well with most exhausts. The only other alternative is the Athena HP70 which is an aluminium kit and will produce more power than the Polini.
Exhaust systems: Again the Leo Vince TT is the best budget exhaust in terms of power for money. The Doppler RR7 or the Polini For Race 3 are the best performing exhausts available but at a slightly higher price bracket above £150.
Variators: The Artek K2 or the Doppler S2BR variators seem to work better on Peugeot engines in our opinion. A contrast spring and three sets of rollers are included so you can play around with the transmission to get your scooter set up correctly.
Carburettors: On Peugeot engines we recommend doing away with the standard inlet and carburettor. Replace the inlet manifold for one that accepts a push fitting for the carb like the Top Racing aluminium inlet manifold. Also replace the reed block for an Enki R2 aluminium reed block then finally a YSN 17.5mm or Polini 19mm carb.
