Gilardoni 47mm 70cc cylinder kit for the Minarelli RV4 engine.
Large 'W' port exhaust and loaded with ports. This cylinder will make serious power for anyone lucky enough to own an RV4 powered bike.
The included intake has an ID of 18.5mm and an OD of 23mm.
For the hackers out there, the RV4 is a very popular kit for swapping onto other bikes. The stud pattern is very very close to Puch and Minarelli V1 and the RV4 engine has a 42mm stroke.
Does not come with a matching head.
Comes with cylinder, piston, rings, pins/clips, gasket kit, and intake.
