Hi: I am new to the forum and would like some help. I have a 06 Streetbob with 19000 miles on a stock 88 engine. It has developed a vibration that causes my feet t o become numb while riding on the highway, also a knocking sound from the front cylinder. I have an extended warranty and the dealer replaced the front motormount. No help. They now say my front cylinder is leaking somehow, even though there are no visual signs of anything. They are also checking the lower end for problems. The warranty company has approved the work, so all I have to pay is $50. Anyone have somthing like this before? I don't care if they gut the motor , I just want them to fix it right.
