For quality reasons! We do not sell this engine with the original first price type ignition, we require the assembly of a PREMIUM MVT !!!
This liquid-cooled engine for PEUGEOT 103 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 lower fuel consumption rate. higher compression, this engine is complete and very well equipped, it has :
-Kit 70cc aluminum liquid cooling with cylinder head, 6 transfers, single-segment POLINI W, automatically, with STAGE 1 preparation
- POLINI housings large valves incorporated support
-21mm intake pipe special flexible mounting
-Adaptation wedge for AM6 / DERBI intake
MALOSSI VL18 valves
- PHBG 21mm DELLORTO flexible carburettor pre-adjusted
MALOSSI air filter specific for SPX / RCX / MVX / CLIP
-Reinforced C3 polyamide cage bearings
-Reinforced crankshaft solid masses DOPPLER ENDURANCE
-Crankcase screws, cylinder head, studs... High quality
-Motor delivered as standard with a small paste to take the mainspring of the SPX / RCX / MVX / CLIP, you can buy a DOPPLER mainspring in your basket, in this case, we mount the spring and remove the small paste! But be careful, on these machines, with special housings, it may be necessary to purchase an SP spring for the front mounting and an SPX spring for the rear mounting!
Everything is equipped, assembled according to the rules of the art (squish, volumes, improvements to the head and bottom end lubrication, etc.), and controlled. To even better accompany this complete engine, you can install the new POLINI exhaust or another model.
Clearly it is still scalable but already very efficient!!! If you want to install a decompressor, plan to buy it because the block comes with a cap!
Give it a good break-in of 400km, and slowly increase the power while adjusting your variation to try to exploit as much as possible the 9,000 to 10,500 rpm over the entire climb range. And check your carburetor settings. 100% synthetic MOTUL 800 ROAD oil highly recommended, 3% during break-in, and gradually (from 200km) down to 2.5% or even 2% (too much oil lowers the octane level and therefore the engine performance, not enough risk of tightening and wear too quickly)!
As an option, we offer an engine preparation, it allows you to operate at a speed of around 10,000 rpm compared to 8,500 for the stock version. This preparation includes a modification of the diagram and the exhaust channel, a slight touch-up to increase the intake diagrams (lateral), an improvement of the intake on the piston and the rear cylinder skirt, a general improvement of the piston. An improvement of the pipe / valves group. To be accompanied by a good motor spring / variator adjustment to exploit 10,500 rpm!
*Delivered without anti-parasite
*Delivered without spark plug, b8hs recommended for break-in and adjustments, br9hix recommended after break-in and adjustments!
*Delivered without variator, the Doppler ER3 is a very good variator.
*Delivered without belt, bring a good quality belt like the DOPPLER
*Delivered without mainspring, the original Peugeot fits well, but a DOPPLER is a real plus!
*Delivered without exhaust, you can accompany the engine with a POLINI , DOPPLER , MVT SP2 or other
*If your original 103 is 6V, provide bulbs and a 12V voltage regulator to go with your MVT PREMIUM ignition
