Ok so I dug into my YZ for a maint check on the valves.... Almost everything is in spec, below are my findings.... Specs EX.10mm---.15mm IN .20mm---.25mm my bike EX .20mm IN .076mm EX .20mm IN .10mm IN .10mm My question is since I'll be adjusting one of the intake valves, should I adjust everything to the middle of the spec? Or just fix what needs fixing? The bike fires on the 4-5th kick when cold, and 1st kick when hot. The bike runs strong, no complaints. Thanks for any input.
