I think I've done something wrong!

That’s be grand, sure! 

I’ actually off to the States next week so I’m going to see what I can find there.

There is a cheaper one. What do you think of the wear. Or is this the one you ordered?

He actually had 4 of these on his website - 400fourbits.co.uk. The one I was going to get (at £60) turned out to have a chunk missing, rather like mine.

I have found another which looks better. Just waiting on response to my offer.

Hi everyone,

I'm back from Belfast, N America, having covered some 14,500 miles on my 750 K2. There were a few hiccoughs along the way but the old girl made it. She has a, now, serious oil leak from, I think, the cylinder head gasket joint That I will have to sort out before continuing in NZ, but that's a story for another day.

So I'm back to Rusty and her top-end. I've installed the new camshaft and sprocket. Because the washer thing I mentioned earlier was warped a bit, and Because N Julie said it was absent on all but the latest F2s, I decided to leave it out.

Sprocket was successfully attached, but I noticed there was a bit of lateral movement after torquing the bolts - about 1-2mm. I don't think this is because I omitted the washer, but what do y'all (American influence  ) think?

I went ahead without the washer/spacer and put the rocker cover on.

Even with a;; the tappet adjustment screws fully out the cover didn't sit flat on the cylinder head, and when I rotated the engine, it moved, rocking  :)up and down a bit on a L/R axis.

Hand tightening the bolts, just until they touched stopped this rocking, but I was hoping for some reassurance, before tightening everything, that this was normal.

You need to be careful that nothing has snagged when the rocker cover is placed on, some using elastic bands to hold rockers in better positioning to facilitate.

I don't think there's any point that will have ALL the cam lobes pointed downwards away from rockers , which means as you tighten the bolts down to close,  then you'll be compressing at least some of the valve springs. This will make it sit up until fully tightened.

Thanks,

I spent an age trying t0 see if something had snagged, and then some more to make sure it wasn't the tacho drive not meshing properly. Then I tried with all the lobes pointing not-up, as far as was possible and this improved things a bit.

With the bolts in place, it is looking better and so tomorrow the plan is to tighten it all down.

I'd like to get it running before I head back to France on Thursday, so fingers crossed.

A little difficult to describe remotely,  but the snag comes usually from the tappet screw face that touches the valve tip "catching" on that tip as it comes down into alignment with the case/cover closing.

Diligence in looking at all of the valves at that location to see that it's not happening should let you gently close the cover by going around equally with the bolts to evenly bring the two surface together.  If that makes sense

I've become a little confused as this thread started for a 400F now it's presumably talking about your 750 K2 oil leak.

I know nothing about the 750s.
