Just an update on this thread - now that the bike is rolling I've bolted the guard up tight and the guard is 'twisted' . When I've checked the upper m6 bolt hole to m8 side bolt hole dimensions and they are 10mm out (comparing left to right hand sides) - so will have to take the welded on captive m8 nuts off the inside of the guard, and elongate the holes to equalise them, then fit loose nuts - thats tpmorrows job
