Aprilia SR50 LC 70cc Cylinder Kit Mineralli LC

All 50cc Yamaha/Minarelli type liquid cooled engine

Air Cooled engine also can upgrade to this liquid cooled cylinder kit

This is Hi-End Aluminum Nikasil- Ceramic Racing Big Bore kit (70cc)

(47mm water cooled cylinder kit)

When upgrading with this to LC engines you must increase jet size and/or get a larger carb to help gas flow to keep engine cool.

A larger 70cc Exhaust is suggested to push the hot air out, if not and you use stock exhaust you could damaged your engine or if you use a exhaust that is only a 50cc upgrade you get same result.

Since engine is mineralli style we have plenty of carbs, jets, air filters and pipes to complete upgrade.
