I recently picked up a 2001 yz426 in june and have put about 20 hours on it since. I have been great about maintenance on it since I bought it and decided to check the valves for the 1st time. I1 .068 I2 .102 I3 .102 E1 .178 E2 .178 What would you recommend I do. Reshim them or replace the valves over the winter. I have no clue about how many owners on the bike of previous doings. It rode solid and I love it.
