The ECU flash has been done and a couple of runs on the dyno to fine tune. Remit was to sort out the snatchy throttle and on the evidence of a short test run it has sorted that out and also improved what I thought was excessive engine braking when letting off throttle at speed. I can now use 1st gear throttling on and off without looking like a bucking bronko.
Extra 4 hp and 5 buckets of torque as an added bonus, thats on the standard exhaust.
Longer test run required but so far i think its a success.
Thank you Bob Scott Bikes in Glenrothes.
