Thanks...tmansk

When it has stalled how do you get it running again, does it start up again OK?
Could be that the vent hole in the fuel cap is blocked, there was a Honda mod to drill a second vent hole 180 degrees opposite the original so that the rubber / cork seal can't block both holes at once.

Try running it without the fuel cap or loosen it after say four minutes and see if that helps.

If you have pipes on the carburetor overflows take them off. My CL would run fine for 5 minutes then act like it was out of gas. I don’t know what the relation was but it now run fine without them. YMMV. Good luck.
