Yeah it's worth checking that first. I haven't done a set of DT cases for a while, I've never done 200 cases.

Less is more then cheers guys. It’s the reason I used hylomar red before, it’s easy to apply thin and evenly… I’ll get out the black mechanic gloves and dab on some RTV…

Yeah, a closed void would be subject to repeated heating and cooling stress. It’s also really handy for helping get the cases split I remember that I crapped myself when I first found it. I covered it with sealant

Typically what are you gaining on a two stroke with engine braking... It's not like a four stroke. When down shifting I always blip the throttle, to both rev match and maybe give it a squirt of oil. I certainly wouldn't be going down a big hill engine braking the whole way at high rpm on a two stroke. Nice blips on the throttle and a high gear to keep the RPMs down. When it comes to competition bikes, well reliability is all out the question and if engine braking does even a fraction of slowing down then it's worth it, but for road going use I only engine brake in an emergency.
