I recently got my bike back from a complete engine rebuild. The mechanic that did the work on my bike told me it was the piston that failed. The nickle plating flaked off the piston, resulting in the oil burning up and the bike siezing in a matter on only about 15 minutes. From full power to seized solid before i even noticed a problem. Oviously it was a bad piston that cause the failure but he also asked me about my riding style and suggested that I modify my bike to better fit it. I was told that the YZ450F is a great platform for all riding styles but not always in its stalk form. It can't be riden full out top gear for more the about 10 seconds at a time like an endro can and it can't be riden slow thru the bush all day either. Not stalk anyway. These are both things that I do from time to time on my old bike. (very old bike haha) So I am wondering what I can do to make my YZ more trail friendly without losing its race bred style. I love to play in the sand pits on the big jumps, and tare up the ditches around my place in the country so I need the suspension that can handle it. But I also often that the bike into tight brush trails where I don't get higher then third gear all day. I am thinking a heavier flywheel will help the low speed riding, and I always run a quality full synthetic oil. Are there any other suggestions for keeping the racey style of the yz bike for a guy that will probably never take the bike to the track?
