Coober ECU issue
I bought a Coober secondhand off eBay the other week for my new shape 390 Duke. It's made a huge difference to the tractability of the engine, and has extended the rev range of the gears in both directions (ie it's less fussy what gear your in).
However, every now and then it hesitates, as though the chain's knackered, or even the cush rubbers are knackered, but both check out. It only happens at lowish speeds, and it kinda stalls momentarily and then gets on with it.
Any ideas anyone?
ETA: I use Shell V Power as a rule (99 RON, IIRC), and use 95 if the 99's not available
