Need help with cold start issue
Hi all,
I really need help with my 78 CB750K not cold starting. I've been restoring the bike over the last few months and it runs well but won't cold start for shit. The list of what I haven't replaced is shorter than what I have. Everything that has to do with fuel delivery and spark has been replaced. I've rebuilt the carbs twice and cleaned them 4 times. Fuel flows and the accel pumps work. Ive synced the carbs 4 times I have 2 brand new agm batteries. New plugs new coils good compression (120 each cylinder). I'm really starting to get discouraged as I've sunk so much money into this bike and it still isn't reliable enough for me to just get on an go. Any info helps, thank you.
