I have had my 998 for just over a week and it is incredible. I am still getting a feel for the bike. One issue that concerns me that sometimes the bike will suddenly surge ahead, but I have made no change in throttle input. I am worried I will be coming out of a corner and it will hit. It is as if the bike suddenly gets more fuel. Disconcerting to say the least. Has anyone seen this behavior before? The bike has just over 15,000 miles with a power commander and FBF pipes. One if the exhaust canisters does seem to have a leak. I know several of the fuel lines were recently replaced. Thanks for your thoughts!
