i also fitted rectifier side today. good quality carbon but i had to fettle the piece where the centre pushes in. also as you say the standard bolts are m6 and i had to run a m5 tap through as was not cleared through. i think some resin was left in there. look great but lacks the centre. going to get one of those.
good choice of colour. can i borrow your red lol.
finally fitted tail tidy and the sent bolts the 2 front ones are at least 5mm short. 10mm short on instructions. they have been informed but it fits great and looks great. raised my termis up to secondbolt level now.
