i have a set of cylinders that are 198/130 (were ported by a local). I want to know if they just widened the exh/transfers or iif they actually changed timings.
Not asking for any secrets here, just stock port timings on 06 non powervalve cylinders

Most people don't have a way to properly degree a 2 stroke's ports...You might have better luck just checking port heights. Measure the height of the exhaust and transfers from the top of the cylinder and post it up in millimeters...as long as your cylinders haven't been "decked", this will give you the info you need.
