remember I said that the owner said it was down on power, well I just checked Tappet Lash, here's the numbers
Both Exhaust Valves .008,,
right side Intake.... 003,,,, '
left side Intake.... .006,,,
I don't know about Saito, but on my Magnum 180 4St I had to adjust the Tappet Lash 4 times when braking it in, .004 or .005 did make a difference in power,,
also, I found that one of the Threads in the Head for a Rocker Cover screw is stripped, I don't know if a longer screw will work, I will look into that later on, but never the less that will drive me nuts the rest of my life knowing that, that thread is bad
