PINASCO 25011840 THERMAL UNIT CYLINDER KIT

Racing Cylinder PINASCO 102 cc for Vespa 50/PK50/S/XL/XL2 for Vespa 50/PK50/S/XL/XL2 Ø 55,0mm, aluminium, 6 ports, stroke 43mm, with cylinder head, M6 exhaust studs, SPORT-TUNING, high-performance& roadworthy For race use only. Not admitted in the area of the German StVZO! On the lookout for something more exclusive? PINASCO is the highlight in the 102cc category. This is a top-class, high-quality aluminium cylinder. The 6 transfer ports provide a clean purge, and ASSO as the piston supplier score points here as well. PINASCO’s nicasil lining and the high quality of the well-known cylinder foundry GILARDONI round off the picture. Thermally less sensitive than anything else available in this category. Our additional recommendation is to spray the cylinder itself with black thermolac. A matt-black surface gives off heat more intensively than a bright surface or a polished one. The PINASCO is certainly suitable for long distances and ideal for 2-person use. Somewhat more down-to-earth than POLINI and MALOSSI as far as power is concerned, but provides long service life. Conclusion: Our touring recommendation for the 'from 100 cc category'. Flawless finish, high-quality aluminium cylinder and the only one that you can ride for long distances and/or long stretches at full throttle. The right ignition and carburettor settings are a must. The primary drive should always be adjusted. Aluminium/ 55mm bore/ 6 transfer ports/ 102.16cc Aluminium cylinder, stroke 43mm, 6 transfer ports, consisting of 2 side transfer ports on each side and a boost port divided into two, pistons with 2 piston rings and plane piston head, 6mm exhaust studs, original PINASCO cylinder head included in delivery, incl. gasket set. Jets should be adjusted. Fits all Vespa 50/PK/XL/XL2 models, except PK automatic. Transfer ports match the originals, engine case can but does not have to be modified. SIP-TiP: Adjust the main jet and install new spark plug, of course. Changing the transmission is a must here, min. a 3.00 primary, max. 2.86 with reinforced clutch and/or stronger springs. Racing crankshaft and carburettor size from 16/ 16 recommended, preferably a 19 carburettor with intake manifold. You can easily make the cylinder happy with an original exhaust with a wider manifold or the SITO Banana###25011840 (PINASCO)
