[QUOTE="Razorback, post: 658774, member: 32956"] 1. What is a flywheel? What does the weight mean? What is the purpose of the weight change? 2. What is a reed cage? The flywheel is attached to the engine crank,it's job is to keep the engine running smoothly.A light flywheel will allow the engine to rev faster and give it burst speed like you would use in motocross to exit corners and clear jumps.When you let off the gas the engine will quickly lose power and may stall without quick and effective use of the clutch.A heavy flywheel will keep the engine running at low speeds without stalling and it will also make the engine not rev so fast making it easier to handle in slow terrain.The Steahly flywheel weight comes in 7,9,11,13 oz's. for the 02 KX250.It is a bolt on item that attaches directly to the existing flywheel to increase the weight and is easily removed. The reed cage is an assembly that directs the air/fuel mixture into the cylinder.It's located between the carburator and the engine cylinder .I can't describe exactly how it works but the flow change will also change the power output of the bike.The Delta Force gives the bike more low to mid range power with a little more on top but I don't have to use as much throttle to get the meat of the powerband.The installation is quick and easy on the KX and replaces the original reed cage leaving the stock one intact. I'm still using the stock carburator jets and needle position even with the new exhaust system and reed cage.The bike runs very clean and sputter free. I don't think having your engine ported is a good idea at this point.The change would a permanent one and if you don't like it your stuck unless you buy a new cylinder.Riders with a lot of experience know exactly how they want their bikes to perform so porting is a way to achieve their goal.
