Cylinder head bolt lengths

[The Gatekeeper]

Hi guys
I'm no stranger to working on engines generally but it's my first zxr400 HG replacement,
After removing the head I noticed that two of the head bolts are about 6mm longer than the others
Can someone please tell me which number holes they came from as I thought they were all the same and didn't make a note

Have a look in the manual....................

Thanks for the link, but I printed out the manual before i started having looked at the appropriate section I cannot find any reference to these two longer head bolts (section 4-14) any other info would be greatly appreciated though
Cheers Darren

If you look at the exploded view here http://www.zxrworld.co.uk/Manuals/H%20M ... er%204.pdf it shows 6mm and 8mm bolts. The 6mm seem to go in the middle of the head with an allen top to them.

Is this what you were looking for?

Thanks for the reply but no, there are 10 cylinder head bolts that have a 12mm hex head, two of these are slightly longer than the other eight but I'm not sure of where these two longer bolts fit
I hope this makes sense

That's what I was looking for, I couldn't find it as its not in the H manual and as mine is a H2 I hadn't downloaded the L supplement
Anyway thanks very much for the help !
