Received the Adige DU-112 clutch kit today and the dimensions are correct for my basket. It is listed as an original replacement for 2004-on 620,696 and 800. While you're here am not sure if the seller was BS-ing me that this motor will go 12k miles between valve adjustments. It has over 40K on it and is within 1k of his recommended interval and it runs strongly. What is your advice?yeah, it smelt a bit like sellers bullshit to me too, but you never know. maybe it has 88mm pistons in it?
