Rebuilding an older 4-stroke ('90 DR350) and some of the inspection tolerances are crazy -- like 0.0004" for the rockers, 0.0006" for valve stem wear, etc.
The OEM tools are crazy expensive, about $850 for dial calipers, $300 for 25mm microm, obviously not buying them anytime soon.
I have some cheap digi calipers that have pretty good resolution but I don't know about the accuracy at that precision.
When you guys are rebuilding/inspecting what kind of tools do you rely on? Do you just do visual inspection and replace with new valve stems/etc., or send to a shop, or do you have the tools?
I guess I'm wondering specifically if there is a good dial gauge, micrometers, dial calipers that you actually rely on for these tolerances without dropping over $1k.
