re-torque head (cap nuts)
Hi,
After a complete tear down, the parts have to find there "place", and indeed the gaskets are suppressing a bit. Also the rings underneath the nuts deform under pressure (that's why you can say that they are used), and the nuts are deforming a bit. All these parameters working to one side (getting less pressure on the cylinder / head), and that's why you have to re torque. Some nuts go 45 degrees, 90 degrees, some 180, and some more. (btw, why not use the specified torque on the m6 nuts ?) Jensen assembly of Japanese motorcycles requires great peace of mind (Pirsig)
Hola Steve,
I'm so sorry, I forgot that there are no tool shops on the isla. And using a common wrench with an simple hand scale isn't available ? Torque (Nm) = distance (meter) * force (newton or kilo's * 9.81) wrench = distance, force is measured by the scale, and there you go.....

I know this will not help Steve or anyone outside the US, but for what it's worth, Harbor Freight (fine tools made by prisoners in China) sells a digital scale that is great for things like measuring torque and other force related stuff. I initially got it to set up the steering head bearings on my road racer. Suzuki actually gives a spec measured off the end of the handlebar. Since then, I've used it for torquing bolts where my torque wrenched could not go and more mundane stuff like mixing things by weight. I've checked the accuracy and it dead on. It is bascially a digital fish scale.
Jensen could check his next weed purchase to assure he is not being ripped off. regards, Rob
Hi,
A hand scale is a meat or fish scale, a simple scale with two hooks, bases on a load cell, and of course digital read out. I use this for years now (my wife is still wondering were it is). Steve, specially for you, a few pictures from our typical Dutch landscape, maybe this will inspire you a bit. Jensen assembly of Japanese motorcycles requires great peace of mind (Pirsig)
