Large crankcases with large intake and support in "bare" version for your 103!
Here are the world famous casings from POLINI for PEUGEOT 103 sp, mv, mvl, lm ...
Attention, they do not fit on PEUGEOT 103 SPX/ RC X/CLIP...
You can also have machining for long stroke crankshaft, just go to the bottom of the description, the option of machining crankcases for long stroke crankshaft will be offered to you!
These casings are made for you if you want:
- Pay less
- Install higher-end bearings as on the packs we offer
- Install studs and a more upscale launcher pedal like the MALOSSI
- Install better quality oil seals
The admission is therefore quite large, it will be able to accept a 21mm carburettor without difficulty, the admission on the crankcase side is micro blasted in the rules of the art and the crankshaft passage polished correctly.
The architecture is reviewed and corrected for better delivery/diffusion, more pre-compression by filling in dead volumes... Of course, the casing transfers are planned to be associated with a large kit.
The pipes are however polished on the inside and not micro-blasted, something that a good preparer will review with micro-blasting before assembly!
The valves are mounted with 2 slats with a division of 0.35mm thick fiber, they have stop slats unfortunately not drilled. We will greatly appreciate the engine support incorporated into the casings and mounted on rigid silent blocks!
Power level, with a good kit, a good carburation and variation, you might as well say that there is enough to fly you away compared to the original crankcases which have a very bad architecture, sweeping and admission because poorly studied.
We will regret a rather fragile alloy, do not hesitate to go there with care during assembly / disassembly!
We recommend at least to accompany these crankcases : reinforced crankshaft with normal bristles, racing cylinder/piston/cylinder head kit, 15 to 21mm carburettor, racing spark plug, racing air filter...
