Complete liquid-cooled engine delivered assembled and ready to run! We have equipped this engine with original-type crankcases and a DOPPLER crankshaft. For intake/carburetion: ATHENA aluminum reed valves bonded with fiber reeds matched to the engine, 19mm angled intake manifold with flexible mounting (you can remove parts from the pack to add other parts to your cart, but keep the screws that have the correct quantity and dimensions).
It is equipped with a genuine DELLORTO PHBG 19mm flexible mount carburetor
For the ignition part, we install a MORIYAMA electronic ignition system properly timed with this configuration; it is a high-end MORIYAMA type ignition with a forged rotor center.
For the top end of the engine, we chose the DOPPLER liquid-cooled 50cc with its cylinder head!
The engine is supplied without a spark plug; in the basic configuration, we recommend a B9HS for adjustments and break-in, then a BR9HIX.
Technical advice:
- Engine needs to be broken in for 500km.
- Use 100% synthetic quality oil at 2.5% in SP98 or SP100.
- To be fitted with the original motor spring (not supplied) and the original spring paste (supplied).
- To be used with an original or racing CDI unit (not supplied)
- To be fitted with a free-flowing original exhaust or a sports exhaust (highly recommended, not supplied).
- Remember to use a good quality belt in good condition! (not supplied)
As an option, we offer a Stage 1 preparation for the cylinder and piston. This preparation involves modifying the exhaust port by increasing the port timing and improving the flow, thus increasing the cylinder's performance. Skirt modifications are also included in this service. Please allow a little extra time for this preparation.
