Refitting cylinder heads

[Demongroover]

I have removed the valve blocks / cylinder heads to get the exhaust studs drilled out.
They are back now, all done and I am ready to refit (with shiny new exhaust).

When removing I zip tied the camchain to the cam sprockets and undid them, so the sprocket could not move in relation to the chain.
The sprocket is indexed to the cam so timing cannot go adrift.

My question is, before I attempt to reassemble, is it easier if I loosen / remove the camchain tensioners, and refit them afterwards?

Yes is the answer Take them out - you usually take them off before removing the cam sprockets anyway. Having said that - I've never tried to reassemble with them in. Try it first and see.

No, makes no difference, apart from giving yourself extra work .

Thanks StepToe!

Well, cylinder heads back from engineers, new exhaust studs fitted.
I have new head gaskets, new rocker covers, gaskets and head bolts.
Exhaust downpipes are polished, new collector and shorty, new (full size) panniers.
Handlebars, yokes, mirror stems and headlamp brackets repainted and refitted.

Now to find some ManCave time to get it all back together!

can you post the details about cost and where you got the studs done. I need to do mine, hopefully the exhaust isn't going to fall off until the end of may, when I want to do it.

I took the valve blocks to Service Exchange Parts - SEP Engineering.
It cost £20 per stud plus VAT.
Worth it after all the buggering about I did welding on nuts and struggling with stud extractors.

Here's progress so far...

Valve adjustment and new rocker covers to go on yet.
