Title: simple modifications to increase power of engine.
Post by: conntech14 on February 06, 2021, 04:56:28 pm

i have heard that a few engines are the same except for the addition  of restriction on the intake, carburetor and  or exhaust. is this true and are there any simple mods that increase the performance of opposed twins. as an example i remember reading somewhere that a 16hp and 21.5 hp engine was the same except for an additional plate in the carburetor that reduced airflow.
