At VMD so include those too, gotta work on 2020 rules so I'm trying the quick version rather than reading the rulebook myself
V2, F500, V3(bump). 350 is pretty much open for V2 now, Rd400 last I checked was more "supersport" limited.
The RD350 was limited to stock 28mm carburetors overboard to a max of 29.3. Looking at the rule book now it doesn’t say stock jut 28mm bored to 29.3.
