I looked back a few pages for several searches and did not find my answer.

My question is, how serious is Suzuki about torquing head nuts every 3500 miles ( I think my owner manual says that, otherwise its 4,000 miles) forever.

I saw one member fixed leak by tightening nut between carbs. Fine. Others had to crack the nuts loose with wrench then retorque. If they resist then let go with snap, aren't they tight enough? Or are we correcting for bolt stretch and gasket flattening? Others had cracked head castings.

If mine don't start their offwards spin easy, and it does not leak which it doesn't, can I just visual confirm no leak and be happy every 4,000 miles?

Or even better can I just wait for leak then retorque?

I don't really know, but it might also be to keep the bolts/nuts from seizing.  Dissimilar metals can cold weld if left like that long enough.  I figured that's why they suggested it at least for the exhaust.
