Finally got the er6n swing arm bolt out last night with the aid of a friend, compression stabiliser (release agent), brass drift , 4 pound hammer and a bucket full of choice words. It was rusted into the spacer tube. I've realised tonight after cleaning everything up that the versus swing arm outer roller bearing had collapsed, the bottom shock mounting bolt is longer for the versus and I have to make spacers for the rearsets to prevent the bolt linking the rear brake lever to the master cylinder rubbing against the swing arm. Are the seals & bearings etc the same as for the er6n swing arm ? Anyone here have the sizes for aftermarket replacements or genuine part nos. Also got the zx10 front end in and busy fitting zx6r race fairing and seat. I will change the front brake to a brembo one as the feed from the remote reservoir is from the side giving better clearance. The racing is on hold at present with this Corona thing.
