I have an 07 CRF150RB that has limited adult riding time on it, maybe 15hrs. The last 2 times I've pulled it out it would not start. Drained gas/carb checked spark and tried again. NO go, not even a hint of starting. Pulled valve cover and took following readings: Intake Spec .006 +/- .001 Left Intake = .005 Right Intake = .004 (.001 out of spec) Exhaust Spec .010 +/- .001 Left Exhaust = .008 (.001 out of spec) Right Exhaust = .009 Would a .001 out of spec intake and exhaust valve create a no start issue with this bike? Pretty bummed they are already out of spec and this bike will not start. Thanks for any input.
