i have bought 2 new motorcycles in my life ( the rest were all used) and broke them both in the same way. my 72 has 112000mi on her and i have never been below the heads in the engine, original rings, pistons, bearings, nothing below the heads has been touched. i will tell you the same thing the guy who sold me that bike told me, ride it like you always will, except for 500mi or so dont hold the throttle in one place to long. i ask about what speeds, he said after 100mi, whatever speed you want, just dont hold the throttle in one position to long. i said...aahhh ok?? well i did that and she held together pretty good i think. so i did the same thing to my 02 and we shall see. another one is, a friend bought a 84 firebird new, we, within a wk., took that car for a 4000mi trip. there were long streches of road that we run that car with the speedo buried, that car had over 200000mi when he sold it and it was still runnin strong???? that is what i have seen in my experience if that helps???? hahahahahahaha
