iv asked this question before but I'm added a picture so you can get a better idea what is on about, i want to take the pipe off were iv circled in red , ( what is this called ) i need to take this off so i can change all the o rings in the sliver pipes which carrie oil up to the cams,
i just need to no if i take this what pipe of is there gonna be any gaskets im gunna have to order because there might be a chance of ruining them, I'm sure there held on with 8mm bolts each side, thanks,

thats the coolant pipe.

Thats a good start :) thanks , do u no if u take it off do I need to replace any gaskets ?

You'll need to replace the o-rings. probably.

Make sure you tighten everything back up to the specified torque too...

I already answered this before

There are four o-rings.. one on each end of the metal pipe and one under the metal block that the pipe bolts into.

If you remove it you should replace the o-rings.

You need:

2 x 91301MB0000 for the metal blocks the pipe goes into
2 x 91301147023 for the metal pipe itself

They'll be all old and hardened now due to engine and water heat over 20 years.. if you remove them they'll most likely disintegrate. i've always replaced them as its false economy not too for the hassle of having to drain the coolant to remove that pipe.

And if the other o-rings on the bike in that area are failing then they wont be far behind

David Silver Spares are really helpful, if you phone them up and talk to them they will tell you what part numbers you need if you don't know.

i no you did neo but i rang DSS and i didnt have a clue want i was talking about so i just wanted to post a pic to get name so i have a better idea of whst im on about, thanks,

i think as well when i removed the oil pipe, i only replace the o ring on the top part bolted to the cylinder and because i never changed the over end i took off its starting to leak oil, just not got the room with that water pipe in the way
