they should be speacial snap off bolts, if they have been replaced then someone must have put cap heads in them, then take the other out and let me know what size it is, i'll drop you one in the post.
Don't forget people there is more to the zxr400 than this forum... check out www.zxrworld.co.uk also.
right, thanks. Ill have a go at taking it off, to be fair I did have an attempt but it is a bitch to get to, like my hand doesnt really fit in to that gap. Ill have another go I suppose.
right, Ive found out what it is. Its a torx M6,, you need a female torx (which I couldnt find) to put it in, and the end snaps off once its tight enough. Well put an M6 caphead instead... seems to do the job. So if the bolt falls out thats holding the ignition barrel in.. its an M6...
Well, I went and bought the part from my local kawa place £1.20 for a fkin bolt, but didnt have the tool to put it in, so I went to the techinicians area whilst I was in uni, and looked in to their stores, compared the thread to an M6 and was prefect match,even tried on an M6 nut on the bolt I bought and was right, so I just shortened the caphead and tightened it in.
