I just bought an 03 wr450. I was wondering about the titatanium valves compared to the steel ones on my 99 400. My old bike is so reliable it amazes me. Should I focus more on maintenance and valve adjustment with the 03? How would I know if the starter upgrade has been done on the 03? I ride on Atka island (Aleution chain) I have the only 2 wheeler here with only 60 people on the island. Plenty of open riding on volcanic mountains with no trees. Does anyone want to ride here?
