Yep that's the old one, I'd ignor those, also remember you measure a countersunk bolt from the top of the head to the bottom..
Shit completley forgot the mrs dragged me Xmas shopping! I can check when home from work mate, I will be back about 2.30pm
cheers bud, they must be different. mine is 25mm. BUT BIG BUT it's a M5 tapered nut that is machined down to a M4 thread. Just spoke to Harris who told me the size and how they have to make the thread smaller to fit the bike but larger head so it fits properly So sorted and many thanks all
Oh FFS, nuts arrived this morning, took some time to arrive and guess what, fecking won't fit. they have mad the thread at the bottom of the M5 Nut a M4 size but not the whole thread. So it won't fit!!!!!!!!! phone call Monday to Harris I feel. and Surprised they did not know thsi as they make the fuel caps!!
