Opened up my engine to inspect it, and all looks good.
The valve springs seem a little weak, and will probably limit the RPM of this engine......but that is just my guess...
8000 is the max reccomended stated in th emanaul anyway...
The engine is timmed at 6/12 o`clock.
But, the valve clearance is no good from the factory....or the lack of it.
Both my lifters where pressing slightly on the valves, where there should be slack/clearance.
So I took my saito feleer gauge, which I think is at 0.10mm and set the valves to that.
Be careful with valve clearance.
On engines like this one I always set valve clearance close to zero (no clearance) but avoiding pressing the valves, when engine is cold.
Best regards
