Well gents, at the suggestion of Ringfad I took a little run down the road to his place to try out a standard chip. Spent a couple of interesting hours chewing the fat and comparing buikes. Simon changed over one of his spare Motronic units with standard chip for my one with the Harmann chip.
I then took the bike out for a run out the country, the difference is incredible. When warm the bike idles nicely at 1000rpm instead of the old 1200. The fueling at low revs is so smooth that it completely transforms the bike, the transition from throttle off to throttle on is no longer snatchy and the bike will pull smoothly from 1000rpm in fifth gear without hesitation. I can't notice any real difference at higher revs.
Over the next week or so I will check out the fuel consumption to see if it improves.
Simon....thanks a million, i'll give you a shout towards the end of next week and we can strike a deal.
