Question


Do the camshafts need to be removed from the cylinder head in order to access the bolts which will allow the head to come away from the main block. The Haynes section on this is poor. It kind of skips the Cylinder head cover removal and illustrations are poor. I know there are some ZZR lovers here. Any help would be great

you would need to remove the cam-chain to remove the head.. so i would think so...


here is a diagram, from the looks of this the bolts (B),© are between the camshafts...

Thanks. From the looks + haynes there are 10 bolts that go down into the body. You can get at 4 of them but te other 4 are half underneath one of the camshafts:(


Thanks for the link should be usefull

if you look at the gasket there is a bolt on each side of the pistons = 10, and to get at would need the cams out... just be sure to lay everything out and put bits together that should be together, i'e no1 valve with spring, and no2 with bits, etc, etc, makes it easier on re-assembly..

just remove the cams its only a two minute job and would make things a bit easier :?


but then you would have to remove them anyway to release the cam chain

havent had to remove the valves +springs. removed the cams. cam chain, tensioner and such. taken the head off now exposing the pistons. the engine running has a knock he thought it was from left side no1 little end moving from side to side. unfortuantely on inspection there is nothing obiously wrong with any of the pistons, gudgion (spelling) seem ok. Job for another day though is removing and examining them. Any obvious things to look for?

Posted

i would have checked everything externally before removing the head, like exhaust headers, and anything bolted on.... one of the guys on here was chasing a noise and it turned out to be an exhaust clamp under the bike.....

Posted
Dont worry the obvious was checked before the head was removed!!!!!! Any hints on what to look for re.faulty piston

 

scoring of the cylinder bore and/or bust rings would be the obvious choice.. colour/soot another.. also irregular movement of the conrod..


sure its not a bust valve??

I am now trying to put the top of the engine back over the pistons. ie. get the pistons back in the barrels. This is proving tricky, Ive been told this is a fiddly time consuming exercise but does any1 have any tips, first time ive done it so dont have a nak for it yet. At the mo we are packing under the pistons with a rag to keep them stable and trying to compress the rings one at a time with our hands to get the pistons in the barrels when we lower the head back on. any tips would be great

you need at least 2 piston ring clamps and a mate... one of you lowers the head the other offers up 2 pistons, then offer up the other 2,

piston ring clamps compress the rings to enable them to slide into the bore.

Cyberwolf/Chris, I don't think your post helps this thread and might be better in entertainment/humour.. it just clutters this one up.

Thanks Walkney

Hadnt spotted those on ebay, just the ones which dont open out fully and therefore be trapped on the rod. Have purchased 2 and will give it a go next weekend. Hopefully can get it done as this is messing up our momentum a bit.

Mightycaz I live in north wales on the way to the ponderosa. Close to the liver in if you know it. Ill be lucky to get out to work tomz

Thanks for the help ill let you know how we get on
