I bought a new leftover 05 WR. I broke the motor in changed the oil and then went on a 30 mile ride very easy one (with daughter on her new quad) after a few days in the garage with the heat off about 30 ish degrees I flipped on the heat and checked the valves. I found that the intake valve on the left side of the motor(cam gear side) is a little tight.I could not get A .004 feeler Gage in but could a combination of .002 and .0015 . should I worry about it or not? Do you think the motor being 30 degrees has any thing do with it? do you think at 75 degrees it might have enough clearance.I put it back together and thought I would just check it again after a few more rides. Or should I reshim it now?
