Advice please on rebuilding a 2005 Monster

[dacs]

Hamish, welcome. I'm not that far from you, in Aylsham. You don't say whether this is your first Monster so the following may be superfluous but the hardest thing I found when fiddling with (sorry, maintaining) mine was dropping the assumptions that come with working on Japanese motorcycles - the design approaches are culturally different.
This link may help https://www.ducatiomaha.com/pages/ducati-oem-parts - drop down the page until you find the appropriate year and model for part numbers/exploded diagrams to supplement the Haynes manual.
Be aware that buying new Ducati bits will avoid the minefield of trying to find second-hand stuff on Ebay, which will fit A Monster but not necessarily YOUR Monster (don't ask how much I spent finding that out).
Ask on this Forum if you have a problem, there will always be someone who can give an answer in my experience. Best of luck with the 4 boxes of bits, I look forward to photos of the completed build.
