Hi All,

Completely stumped by this one.

Bike revs completely normally all the way to redline in neutral or with the clutch in. Take it for a ride and regardless of what gear the bike is in it bogs at 4,000rpm to the point it wants to cut out. Whether throttle is slowly opened or moved quickly doesn't make a difference. Carbs have been ultrasonically cleaned, bench synced. Waiting on a manometer to properly sync.

My thoughts are leaning towards ignition? I've replaced the coils and am waiting for a new condensor to show up as I think this could be causing the issue? It appears after cleaning that my advance mechanism is working well so I don't think this is the culprit.

Has anyone else had this issue? I've been chasing my tail around this one and its getting the better of me.

Thanks in advance guys.
