I am converting my wideline cafe racer from road to race, and reading the ACU regs no. 14.13 regarding rear mudguards, I cannot find a single picture of a Manx Norton which would meet the 20 degree rule, they are more like 50 deg from mudguard end to wheel centre. Is this reg widely ignored by scrutineers, or might it fail ? I don't want to risk it, but would not like the look if the mudguard came down that low at the back. Any experience of this please, and advice. Thanks, Mike.
