Have a 800ssie and there is an annoying snatching when at low speeds and when i'm n & off the throttle. it a problem with low speed tight long bends when you are balancing the lean withe the throttle (if you know what i mean) and need a smooth throttle. chain is adjusted correctly. its a 05 bike with 3800miles. its most apparent when carrying pillon when you don't really want full throttle of corners. I suspect its poor fuel mapping on the ecu but anyone else had problem and found a cure with out a power commander.
