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?

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

Had some time to go to my friend, he has a ships engine repair shop.
Made the test deutz cylinder to the size I wanted.
1 step closer to building.

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..
