Hi,
My 79 sr500 has no spark over 4000rpm.
At 4000 rpm floods and then backfires, in all gears and won't go over 4000.
I bought a timing gun and realized that there is NO timing advance as I increase the rpm. At 4000rpm the spark stops and on deceleration only comes back around 2500rpm.
From what I have seen the CDI either works or doesn't work. Is this correct?
The bike has a new spark plug and rewound stator.
Thanks
Quentin
