Complete engine POLINI 70cc liquid for Peugeot 103 SPX, RC X, MVX, CLIP ... (flexible assembly)

For quality reasons! We do not sell this engine with the first price original type ignition, we impose the assembly of a MVT PREMIUM!!!

This engine for PEUGEOT 103 liquid cooling offers more performance and reliability than the air version, liquid cooling allows more ignition advance, to run with a leaner and more explosive air / fuel ratio, and allows a rate of higher compression, this engine is complete and very well equipped, it has:

MVT PREMIUM ignition set at 0° (choose electronic cone)

-Kit 70cc aluminum liquid cooling with cylinder head, 6 transfers, mono-segment POLINI W (prepared or not according to your choice)

-Carters POLINI large valves built-in support

- 21mm flexible intake pipe special POLINI casings

- POLINI carbon valves (you can place more efficient valves in your basket if desired)

-Carburetor PHBG 21mm SOFT pre-adjusted

MALOSSI E12 filter

-Reinforced bearings C3 polyamide cage

-Reinforced crankshaft full masses POLINI (the most qualitative on the market)

- Crankcase screws, cylinder head, studs ... High quality

POLINI motor spring

POLINI launcher pedal

The whole is equipped, assembled according to the rules of the art (squish, volumes, improvements in the greasing of the big end and connecting rod feet, etc.), and checked. To better support this complete engine, you can install the new POLINI exhaust or another model.

Clearly it is still evolving but already very powerful!!! If you want to install a decompressor, plan to buy it because the block comes with a plug!

Give it a good run-in for 400km, and gently put the power on while adjusting your variation to try to exploit the 9,000 to 10,500 rpm as much as possible over the entire climbing range. And check your carburetor settings. 100% synthetic oil MOTUL 800 ROAD strongly recommended, 3% during the break-in, and gradually reduce (from 200km) to 2.5% or even 2% (too much oil lowers the octane rate and therefore engine performance, too little risk of tightening and too rapid wear)!

As an option, we offer an engine preparation, it allows to operate a speed of around 10,000 rpm against 8,500 for the stock version. This preparation includes a modification of the diagram and the exhaust channel, a slight retouching to increase the admission diagrams (lateral), an improvement of the admission on the piston and the rear cylinder skirt, a general improvement of the piston. An improvement of the group pipe / valves. To be accompanied by a good motor / variator spring adjustment to exploit the 10,500 rpm!
