Has any of you lads ever had or heard of little ends knocking on a YB, as ive had my engine rebuilt because of a knock and guess what its still there. The only parts used from my old engine was head and con rods, and the little ends wasnt changed. After it was done i took it back and was told it must be the tappets as every thing else was new so changed the tappets along with new cams and still no good. Ive now took the engine back and asked the bloke who built it to check the little ends but he said theres no chance it could be them as he has built 100's of ybs and never had to change them. I dont wont to say who built it as hes got my engine now and may be sorting it, but lets just say hes one of the best engine builders in england and it cost 6k. What do you lads think ?
