Installed the new vaccum release plate and seal on the weekend. Fits well and works perfectly. No noticeable difference to the OEM job. I am going to monitor the wear rate to establish whether (and when) I need to get a spare to keep handy but I suspect and would hope it will last well beyond that of the OEM one. Above plate was from here and was in my mailbox exactly 14 days after I ordered it. http://www.ebay.com/itm/271403088616?item=271403088616&viewitem=&sspagename=ADME:L:OC:AU:1120&vxp=mtr And the seal for it was from here: http://www.showandgo.com.au/ My bike is now running the best it ever has. Incredibly smooth and the power delivery is just awesome from right down low. What used to feel like lugging the bike in top gear at town speeds (60-80km/h) with road gearing is now just perfect and I am not having to chop up and down gears all the time. At 100ks an hour and beyond, it just wants to keep pulling further than what I am game to go because of the 'law'.
