Re: Can you lift your front tires now?

I'd like the gauge sent to me as well. /forums/images/graemlins/smile.gif

I found it easier to access the lock nut and set screw by first removing the knob, boot and shroud. The shroud is held on by three 13 mm bolts.

I turned the set screw in 1/4 turn which, according to Spencer's experiment, should equal 125 psi more.

Ok, here is some info.

If you are really talented you can adjust the setting without taking off the metal valve cover. if not, you will need some bendy tools to get at the screw on the side of the cover.

Using a 1/2 in wrench and allen wrench at adjustment point.

First reading. Note, the instructions call for running the engine at a high rpm (2600 I believe). I found that running and testing at this rpm produced a spike in pressure of an additonal 300 psi which then bled down quickly to the relief pressure. I tested mine at my usual operating speed of 1500 rpm and got the same reading without the spike. Test yours as you see fit.

After adjusting down from 2100 psi. Ooops, too low !
