Athena (070100) 47.6mm Diameter Aluminum 70cc Sport Cylinder Kit

This cylinder I don't care what anybody has to tell you is just as good if not even better than all the big name brands like polini malossi etc etc if u at the very least put a 17.5mm carb a yasuni r the big valve intake with V-Force reeds and a crank The only other thing that would touch you would be the Athena hyper race and then of course you know then you get into the exotic stuff like 2fast that produces a 70cc engine that have tuned properly makes 33 horsepower to the rear tire on the on the dyno that is absolutely unbelievable how that is even achievable on oh and by the way it was 110 octane gas it wasn't no methanol or alcohol or nothing like that it was 110 gas making 33 horsepower yeah you wouldn't stand a chance against something like that with this cylinder or nothing like an RC1 by malossi basically I can't personally tell you of any better of a cylinder than the Athena hyper race and maybe and that's a big maybe the MHR replica

Much better than the cast iron cylinders. Increased power right out of the box

Athena Minarelli vertical cylinder kit, open box sale, has signs someone opened it and greased it up, chamfered the ports but clearly had never installed or ran it and returned it..$69, my last Athena Minarelli cylinder cost me around $100 more. I've bought 3 for this price, two were like new.

These ports are huge and they're super clean great little top ends Athena Rocks

Excellent!!! Very pleased. I put on 86' Yamaha Jog CE50. Vertical Minarelli. Install was easy, but I needed to order larger intake manifold. Went with Stage 6 intake kit w/ larger valves, larger Jet. (From #85 to #95 jet)
