  1. I'm new to the thread and was hoping you guys could help. I bought a 03 yz450. Its my first 4 stroke and I'm looking to get back into racing after a long absence. It will be about 50% track and trail. What do I do about the tall first gear? How should I change the gearing so 1st isint so wide and stalls so easily on tight nasty trails? It has ti FMF powerbomb with Ti4 muffler. It pops really bad (loud) when engine braking. Is this normal or a jetting problem. Supposedly the dealer I bought it from checked the valves. How reliable are these motors? And finally, where online can I get a printable manual? Ive looked and looked, and dont have the money to buy one. Thanks ahead of time, and man these things rip!!!!!!!
