Ok need a bit of help.
Some say de CB650 valve springs are a bit of an overkill for my cam/light cam followers, and that I can get away with
single springs with that cam and light parts. (TP type 1 lifters, Webcam 86b)

So would this be a n option than?
https://www.csp-shop.com/en/engine/valve-springs-109-623-010jpm-24961a.html

Other question can I get the spring pressure up by shimming the valve springs to the correct spec for the cam?
Help appreciated.

Ok got Al the parts now.
Went with JPM single springs + Titanium retainers, on advise of Johannes.
Busy with cleaning of the case.
The case / heads are ready to be machined.
Using the heads of 2.0 engine, only 10.000 km on them.
Valves were not leaking... Never cc the heads, did this now they are off...
They are all 45cc just what I was told when I had them built for the 2.0 engine. Grin

PS I now this is not the correct way to cut the cylinders, but this is the test cylinder.

After some info and advice, I am going for heads 113mm and case 107mm (106mm).
So Cylinders will be 0.2mm less.
Removed a little bit to much from bottom... but this is the test Cylinder.
And haven t decided yet if I go 107 or 106mm..

Ok a small question, on a carb engine when do you need a bigger fuel line, when is the original 6mm fuel line not sufficient anymore?
Is there some rule of thumb?

I know for Injection you need a bigger one plus return.

Ok will try to route a bigger Fuel line from the front to the back...

The parts are out for machining, but I don t think I will have the new engine ready before season start,
so decided to put my old engine together, with some standard CU heads.
Had some extra stuff laying around like H beams.
Crank rotates smooth in the case, camshaft also..

Am curieus what this will bring. A little modifications to my old 2.0 engine.
Using the heads for the 2.4 engine build.

Throw in some parts I had lying around.
Lighter H beam Rods, standard CU heads 39 x 33mm valves, new valve guides, a few new valve seats, lapped the valves and valve seats,
flycut the head 1 mm, deck height on old engine was to big... so set deck height now at 1.25mm this will bump compression to 1 : 9.7 now.

Fingers crossed it will fire up.

Well if you clamp it like this in the vise of the lathe it leaves marks you can not hone out.
But this being a test cylinder it did not matter.

Ok did some mileage on the engine. (EBI about 800 km trip)
Found out some interesting stuff.

This is the 2.0 engine minus the heads, so same engine as before but with standard CU heads (using the other heads for the 2.4 engine)
So standard 39x33 valves.
Deckheight now 1.25 mm compression stayed the same 9.5/6 static.
First things i noticed it does not like a lot of advance of the distributer, had to turn it down from 31 to 28degrees..
You could feel it pinging on high RPM s.

I use Porsche swivel feet….. damn those are hard to adjust...for some reason it is difficult to put the feeler gauge between the valves
and the swivel feet because of constant moving of the 'head'... but ok..
Did a few 100 km then adjusted them to 0.10 mm … well for some reason the engine does not like this…
not pulling strong anymore…. feels very lazy.. so did put the back to 0.15 and power was back....
A bit strange for me that this small adjustment had so much influence..
Using alu pushrods… so thinking they don t like tight valve clearance on type 4 engines.

And how did it pull, well it is pulling as hard as the old engine in low RPMs, only lacking the power above 5200 rpms, than the power is gone..
It is moving to little air I think with the small valves to keep pulling till 6500 like with the old heads..

It is a very nice bottom pulling engine now...
Ooh it is also a lot quitter..  

Enjoying it this summer, building the other for next year...
