A major change in technical rules usually triggers a freezing of any existing UIM speed record.
An increase in minimum weights is normally introduced to reduce top racing speed. For example Bob's previous world OSY.400 record - with no minimum weight - was 72.03 mph, but his recent attempt achieved only 70.12 mph.
