Big thanks to Jonny who sent me a boot divider panel that was missing on my car :thumbup:
It fitted like a dream.

Although it's freezing cold here I spent some time in my workshop. With some double layered clothing and an electrical radiator it is just fine.

Checking the camshaft timing and the valve clearances was still on my to do list.
As the VHPD uses solid lifters the cams has to come out to get access to the shims hidden beneath them.

Valve clearances before adjustment:
cylinder--------1-------------- 2 -------------- 3 ------------- 4 ----
inlet ------ 0.16 0.16 -- 0.16 0.18 --- 0.14 0.20 --- 0.20 0.20
exhaust - 0.24 0.24 -- 0.28 0.26 --- 0.30 0.28 --- 0.28 0.28

Dave Andrew commented over at seloc that the clearances are 'just about tolerable'. I decided to adjust them anyway as one of the camshaft seals was leaking and needed to be replaced.

The procedure is as follows:
- measure the clearances before disassembling
- disassemble the cam ladder and remove the camshafts
- measure the existing shim
- calculate the new shim size to achieve the required clearance (0.20 mm inlet, 0.25 mm exhaust)
- order new shims or try to re-use some of the old ones
- reassemble the camshafts using anaerobic liquid sealing
- measure the valve clearance and hope that it is fine. Otherwise re-start again :-(

I ordered shims which are used on KTM motorbikes. They come in the required diameter of 10 mm and in 0.025mm steps of thickness.
Unfortunately some of them were 1 to 2 hundreds of millimetres thicker than stated.

Valve clearances after adjustment:
cylinder--------1-------------- 2 -------------- 3 ------------- 4 ----
inlet ------ 0.22 0.22 -- 0.21 0.21 --- 0.22 0.19 --- 0.18 0.18
exhaust - 0.28 0.27 -- 0.24 0.24 --- 0.24 0.24 --- 0.27 0.24

Although it's not perfect I'm quite happy with the result. As you can see on the inlet valves of cylinder four
just dis- and re-assembling plus new sealant may change the clearances although the same shims are re-used.

Cheers, Klaus

Merci Julien :)

I'm still chasing my slight stuttering problem and so I checked the compression today.
With warm engine, all plugs removed and at full throttle I measured the following values:

1: 16.50 bar
2: 17.0 bar
3: 16.5 bar
4: 17.25 bar

I'm surprised to see such high values. Almost Diesel-like. Is this common on VHPD engines?
But most important the values are pretty close to each other.

I start with some white spirit to remove any surface dirt and grease. Then I'm using 1200 to 1500 grit wet and dry paper together with 3M Finesse-it compounding paste as the wetting component. This helps to flatten small scratches and marks. From my experience the anodizing is quite robust and does not suffer from the very fine sanding paper.

The 3M-Finesse-It is my personal cleaning wonder weapon. I use it to clean a lot of stuff including all sorts of plastics and painted surfaces. It doesn't contain any silicon and is easy to wipe off.

But I'm sure there are plenty of other good ways around to clean the chassis.
