45mm 70cc reed valve cylinder for various Puch mopeds like the maxi, newport,pinto, swinger, murray and many others. 70cc size will increase power dramatically. "No replacement like displacement!"
With reed valve technology this helps provide best throttle response through all RPM ranges. Works great with either clamp on or rubber manifold mounted Dellorto PHBG carburetors.
24mm intake mounting diameter works perfectly with Amal/Arreche or PHBG clamp on carburetors
Currently does not come with gaskets. Link below.

Cheap Puch reed bang for buck!
"the best budget blaster kit" 50MPH at 10K RPM (16x40) and it climbs hills too on stock port e50 with roller crank, 45mm low-comp head, PHBG21, de-baffled estoril, and tuned clutch. Requires 3+ mm of base spacing to clear exhaust at BDC and decking or counter-sunk head to get the squish back in spec, resulting in some extreme port timing. Rings need gapping. Wrist pin clips are made from paper clips, replaced with malossi units. Replaced steel reeds with carbon for safety. Details here: http://www.mopedarmy.com/forums/read.php?7,3839377
