Hello!
My CB750F Supersport 1982 wont pass 5000rpm.
I bought it in July and restored it entirely. Turned it on a month ago for the first time and since then just low revs to adjust cabs, leaking, etc.. all good so far.
Toke it for a ride today. I don't know how to define what it does but feels like she is choking when I try to pass 5000 rpm and it wont pass by any chance. It runs perfectly fine under 5000rpm, but wont pass.
U guys think it is an ignition timing issue? Or it is more likely to be the carbs not delivering enough petrol? Or lost of pressure in the intake rubbers? WHat is the most common cause for this kind of issue.
I have attached my timing. I did it static, don't have the strobe tool.
