RE: Brand new 30.5cc big bore stroker motor
To begin with I´ll use my FG performance pipe. I suppose the engine could use a slightly larger pipe so maybe I´ll enlarge the FG pipe later, weld in a piece of pipe at the thickest part to increase the volume. I haven´t made any calculations yet as to how big it should be, all that is in the future.
An over the counter option is the RN Tuning fat pipe, from what I´ve seen it looks like a perfect match for this engine..
