At this point I can't even remember the details of the forum discussion that brought about my particular motor oil choice, it was a long time ago but I seem to recall that the decision was based on the motor Delvac having the highest zinc content. None-the-less I have been using it in my 2002 SV650s (Newbike) for years without issue and it is around $13 for a gallon which is a good price.
Once that is done you thumb the starter switch to turn over the engine and until the gauge hits it's peak, and record the number. Then you release the pressure with the valve below the gauge.
My Left cylinder was 100psi and the right was 110psi the rule of thumb is that they should be within 10-15 lbs of each other I need to do some asking around to see what the lower acceptable limit is for the bike though but those numbers seemed acceptable to me so I figured I'd have to look elsewhere for the cause of the smoke. I still would like to do a leaks own test to see how well the cylinder holds it's pressure and for how long, if I can find the equipment to do that it will be the next thing on the list to do.
Check back for an update soon, I have a few to crank out and this is the first installment.
