For the TSR engine cover pricing, I paid around $800 for mine. It came with the water pump and hose too. Pricing varies depending on the Austrailian exchange rate. One thing important to note is that the clutch cover is unique and not the KX450 one so order extra gaskets from him unless you want to pay big shipping and wait several weeks when you need a replacement or have your own made. The material is not strong and tears easily too.
