Puch Moped 43.5mm 65cc Cast Iron Metra Kit Puch 43.5mm 65cc Metra Kit

BACK FROM THE DEAD

puch 65cc !!nikasil!! bore cylinder kit new in box with all gaskets ready to be mounted on any puch moped including but not limited to : Puch Maxi, Magnum, Dart, Cobra, Swinger, Pinto, Freespirit, Newport, Kromag; E50 (one speed) or ZA50 (two speed) engines. Some two speeds may have a tiny metal nub in the case that needs to be filed down in order to make these kits fit. It's super easy. For superior performance skip the bing route and use a dellorto 19-21 phbg on these to make them beastlike. Intakes usually available for one speeds, OR save some cash and take an old exhaust header from a tomos or italian bike and chop it off and make it the perfect o intake. If using the dellorto intake we sell get the clamp style dellorto, for the exhaust header intake use a rubber mount style dellorto. dreamy. Using a 19-21 phbg brings these kits to life and increases power throughout the whole range, no loss at all. plus we all know bings suck and are fully overpriced, hmm. no more cast in studs thank you based god.

product description has not been changed to retain the vintage lingo circa 2007. enjoy

***UPDATE 7/23/18 these now come from metrakit with an improved piston!! the locating pins are correctly pressed into place. the overall quality seems to be on par with that of the airsal replacement and should be great for many miles of ripping. please double check the ring gap n have no more worries! be free!***

gaskets included may differ from the ones depicted in the photos!

need a perfect head for this? look no further
