Never had a problem with DVT after changing belts. Just take the same care you normally do. I do check the live camshaft readings but it's always been OK. Probably make an arse next time I do one now
I do check it before and afterwards (via Texa) but it’s a bit belt & braces. However, as their someone else’s bike I’d rather be 100% right, plus I have the diagnostic tool to do it. I’d recommend getting a crank locking tool though and something to lock the vertical intake cam.
