2100 EFI - First impressions

Well I been driving the 2100 for three days now and it copes fine everything I've thrown at it. It had a wierd airlock issue where it sat at 100deg for 20 mins before I could stop and check the coolant - opened the cap and it burped and went to 80deg immediately.
Power and torque is excellent - pulls well from 2000 starts really building at 4200 and is bonkers at 5500-6000. Should go to 7500 but need to check it over, retorque and do the tappets and get another 500 +miles on it before a real flogging.  Exhaust note is very Nigel Gair PLL110L so mission accomplished!! That was the inspiration back in 2004
