My first PPG engine was Vittorazi Easy 100 assembled with frame from Fly Products. I bought it used condition and I was flying it more or less successfully for over three years before selling it in 2019. During this period I naturally encountered some problems I tried to find solutions on the internet, but the owners’ community of these engines is next to non-existent. The available information is scarce and scattered so I decided to gather everything I know and write it down; some needy soul might find it usable.
So called Fly 100 engines have several versions:
- Easy with belt transmission, propeller rotates counterclockwise,
- Evo with gear transmission and centrifugal clutch, prop rotates clockwise,
- Evo 2 and Easy Plus which seem to be face-lifted versions of their respective predecessors.
I gathered here all documents about these engines available on the Internet. I won’t repeat information contained in them, browse them first then read this post.
- Owner’s manual
- Easy 100 dimensions and mounting
- Easy 100 exploded view new and old
- Easy 100 parts list, to be used with the exploded drawing
- Evo 100 parts list
Replacement gaskets can be cut from sheets of gasket material. I have measured the thickness of some gaskets. The names mentioned below match the names in parts list document.
|cylinder gasket||0.3 mm|
|carter gasket||0.5 mm|
|carburettor gasket||1 mm|
Bearings and seals
All of these are standard components and can be replaced by parts obtained in any mechanics’ shop. I list the components originally mounted by Vittorazi for reference.
- crankshaft bearing (code A003 on the parts list):
FAG 6204 C 2HRS C3
- crankshaft seal 32/20/7 (A004)
LYO 20383 TC 20 32
- piston rod bearing (A008) - needle roller bearing, 16.2 mm width, inner
diameter: 14 mm, outer diameter: 18 mm, no markings; replaced with
BARIKIT METAL 14X18X16
- belt transmission bearing (A118):
FAG 6004 C2
- small transmission bearing (A108):
SKF 608-2Z C3
No visible markings. I was told by the dealer that this very same coil is used in some Polini and Simonini paramotors. I also found it was used in Tomos A-35 and Tomos A-55 mopeds. The coil has two windings - the one wound with thick wire is for battery charger, the one covered in black insulation tape is for driving the ignition module. In my case the ignition winding was partially shorted, causing erratic ignitions. Healthy coil has following resistances:
You may look for the coil and CDI modules with following search queries: Iskra A-35, Iskra A-55, Tomos A-55.
IDM 54 2523
Apparently the same CDI ignition system is used in Tomos A-55 scooters. Detailed information about CDI ignition system used in Tomos. The CDI module may be different but the general idea is the same. Probably you can use any other CDI module with two pin input.

Original piston has following markings:
ASSO 2167. I haven’t been able to find replacement piston
so I bought genuine replacement, including rings, pin and clips, at dealer’s shop. This one is
manufactured by Meteor. The label says:
PC1591B PISTONE VITTORAZI 50 SEL.B Ring S0500010021030KB2249 Pin SP140420090H Clips AN0B1410
Dimensions: length 41.5 mm, diameter 14 mm.
Piston ring 50 x 1 mm, chromed
No further information.
Original cylinder has no markings. I heard some rumours that it’s possible to adapt cylinder from some
Peugeot scooter, but I didn’t manage to find matching cylinder at Peugeot’s dealer. Replacement
CLN: 000481 written on it.
