Hi guys. I've been posting here lately in order to get done help rebuilding this old bike. I promise that in the end I'll post photos. No worries.
So, my problem now is that it starts, but very hard. It can take 5min and cables to my car in the end. Once it starts it's ok. When it gets hotter it starts well too.
Aldo, when running does some backfires.

What's new: spark plug
CDI
Stator generator ( 300ohms)
Starter relay
Battery
Air filter
Carburator.

So, why ?

Check valve clearances.

Adjusting the valve lash will require you to confirm the top end is properly timed to the crank.
You have fuel, fire so the timing (engine adjustments) need attention.
