14° before top dead center with around 17 thou of inch point gap is where you want to start for coolest temps if running a kit (but if you’re backfiring ba you could be really retarded) adding timing only if it runs cool on prolonged full throttle runs,
What is the head temperature when it does it ? (don’t say you’re running a bike without a head temp gauge because that’s a no no)
Is your plug cap low ohms ? (O to 1k ohms is best for points ignition and 10k cap is a no no)
Are plug wire and ignition wires all in good shape no loose connections?
Very dumb even to think of running a bike kitted or not kitted without servicing the magneto area first so if you are running the bike without a temp gauge, without servicing the magneto/setting the timing do not run the bike no more!
It’s easy to service the magneto by Removing the flywheel cleaning/derusting the cam and lubing it and point pivot pre-loosening Stator and point setting screws so they won’t strip when you set gap and timing through the flywheel when it’s back on, then setting point gap correctly, find top dead center and set timing with a timing light at speed (3-4K rpm),
I didn’t write this, someone used my words but it may help you with finding top dead center and timing points ignition on a puch
