@ThatAnton Those Jasil/TopRacing crankshafts from PJME are excellent, trued and ready to fit and seem pretty good quality. I used one to rebuild my '93 without any real issues, TBH I only rode the bike a few times before selling it but the new owner seems very happy with it 12 months later.

They only fit the DTR but if you have a DTRe, a company in France makes a shim to get the flywheel in the right place:

@Calum Thanks bud 👍

@mbmO8 This explains the YEIS box between the carb and reed valve better than I can:

When working around that area it's not that difficult to remove as long as you have a decent pair of pliers to squeeze the clip on top of the reed block, just stuff a rag in the hole until you refit it. The one behind the carb on later bikes, I've never owned a DTR with one of these fitted so maybe someone else can help out explaining this? I see a lot of people blank these off with the lid off a Coke bottle.
