hey there dude, your in the same boat as me, i´m 6´4" and i´ve found the same problems with my ZXR H1( same colour scheme also). i fixed the prob by installing shorter linkage arms to the swing-arm shocky linkage ( just 5mm shorter as clearance is minimal between shock & swing-arm bracing) also i installed a hyperpro progressive spring. also make sure the ride height adjuster is set properly ( dot on drum in line with slot on clamp)
