If your OS 40 4 stroke goes for a fortune and that gets you going on working on that stuff please put me on the list for a Adjustable Lanova chamber...... I have some engines I want to convert and see no point in making my own Lanovas if you are going to do them...
Treven.
There are not enough to put adjustable lanova camber in 4 stroke engine, you must remove material in cylinder head to increase compression ratio and shortening push rod and drill a bit deeper in the seat holes in the crank case (valvelifter) for push rod cover to fit between cylinderhead and crankcase.
