cyclinder head.

Does anyone know if the FZR 600 cylinder head, will fit the FZS 600. I have really had some bad luck with broken downpipe studs. Or has anyone got a good FZS 600 head with all exhaust studs by chance. Many thanks

You shouldn't have any grief with exhaust studs if you are removing them the right way

Why do you need to replace the head? I had two snapped flush and just took the entire engine to my local engineering shop and they drilled them out and re-tapped all for like £30

I had 6 snap flush, and a new head (including valves, springs, shims, buckets, cams) was only £50, getting them drilled/retapped was quotes of £150 onwards everywhere I looked

Wow, thanks for the help, will drop engine
and get them drilled and tapped, many thanks.

Ah, that's fair enough - expected a second hand head to be a lot more expensive to be honest

Its a pretty easy job, did it myself in a day back in January when it got dark at 4pm :P

Putting it back together is a bit more fiddly but managed to do it again in a day with the help of Exupnut as well. Its a good learning experience as well

I hope that wasn't a skilled mechanic who snapped 6 studs in a row?

It wouldn't have mattered who done it - They were soaked in penetrant for two weeks, there was very little of the exhaust nuts left before the procedure even started. I'm not sure what they're made out of on the fazer, but it's most certainly not standard. I kept some of the nuts in a bag to show people, if you press them between your fingers they actually crumble.

I know plenty of skilled mechanics, and I also know the procedure very well - they wouldn't have done it any differently. The best chance to remove them successfully would have actually been to dremel the nuts off, but due to the awkward frame of the fazer that's almost impossible.

[Dead Eye]

Agreed, mine were like cheese

I actually snapped 7 or the 8 but only 2 snapped flush with the head. I was able to remove the others using a stud extractor and an impact driver

Ive had them out of a 95,000 fazer before they were rusted to high heaven. I heated them up until they were glowing orange. I didn't have an issue with them to be fair. If I had snapped one. Engine would of been out and on the bench straight away. If one snaps generally you know what your working with then.

Seems pretty lucky then, were they definitely the original downpipes? Unfortunately there's no way to get the engine out of the frame with the downpipes still attached as the center two go through the frame (unless you take the pipes off with an angle grinder, I guess)

What really hacks me off about this is when I replaced my exhaust last year I managed to get all the nuts off ok. I reused them knowing I'd need to replace them. Yesterday I set about doing this. Stupidly the first one snapped because due to not much sleep the night before and not thinking I forced the nut off without easing it back and forth to loosen it. The second one, well that would have snapped anyway I think. Another one was so badly rusted it unscrewed the stud out of the engine. Not so much of a problem.

To remove my broken ones I'm going to cut a slot in the end of the stud with my dremel. Then heat the head with a blow torch to expand it away from the stud to loosen it. Hopefully this will work as I can't be asked removing the engine.

I have several heads with good studs

Hopefully you'll get it sorted.

Use copper grease on the studs next time and you'll never have a problem. I've had my down pipes off a few times to clean them and the nuts come off easily.

I use copper grease on almost everything on my bike now.
