This is the third start, the radiator was removed to retighten the exhaust and redid the valve clearance.  Thank you zggtr for all the helpful advice and technical information. 
Bike is using ZX11 pistons (2 mm overbore) on 1989 ZX10 rods, Vance & Hines ignition advancer, GPZ900 cams and carbs with a Dynojet stage 3, Supertrapp slip-ons.

Nice! Sounds and looks good.

I thought the first year of the Concours was 1986.

You're right!  Opps 1986
