Just thought I would share what Mark Zimmerman wrote in an email about the JPaige method:

Mort,
I've been checking push rod Triumph valves like that for years, and think it's a fine method of obtaining the correct clearance, whether you're adjusting tappets, valves or lifters. I didn't realize Volusia guys were doing it, which just goes to show you there really isn't anything new under the sun. Thanks for sharing the tip, it's a good one.
Take care,
Mark Z

Throw away the feeler gages, back off 1/8 turn for intakes, 1/4 turn for exhausts.

If you do the math, you convert the pitch of the screw into degrees of rotation.

.75mm pitch = .02952756" per revolution = .000082" per degree
intake .003" to .005" = 36-60 degrees (call it 45)
exhaust .007" to .009" = 85-109 degrees (call it 90)

Sooo, to achieve the clearance for the intake valve, loosen the lock nut, screw the tappet down until it touches the top of the valve, and then back it off 45 degrees (1/8 turn) Same thing for the exhaust, back off 90 degrees (1/4 turn).


Ride Safe,

This is the way we did the Moto Guzzi...However, at least we could get to everything really easy!!! We didn't have to do it that way. Feeler gage fit easily with those Guzzi's!!! :wayhappy:

My brother and I are heading for Deadhorse Alaska, taking the entire month of July and then some. Heading up the west coast to Washington, then cutting inland to Seattle to see my aunt. Then north to Vancouver B.C., Taking the eastern route up thru Dawson city, Watson Lake, Fort Nelson, The Klondike Highway to Dawson Creek, Top of the world highway. Stopping of for a night with Wild AKMoose just south of Fairbanks. Then 4 days up and back to Deadhorse, 400+ miles of gravel each way, 300 miles above the artic circle.

Deadhorse, also known as Prudhoe Bay, is the farthest point north you can travel by "road" in North America, on the shore of the Artic Ocean. This is the northern tip of the Tip To Tip Ride. The other tip is Ushuia, Argentina, the most southern most point you can go in South America. But that's another trip... and a couple of years away.

Then coming back thru Anchorage, and taking the western route thru Whitehorse, the Steward highway down to Prince Rupert, and taking a ferry to the northern tip of Vancouver Island. Another Ferry at the bottom end of the island to Port Angeles. Tour the Olympia Peninsula, then head for Portland, OR. From there, head for Lake Tahoe. Then on to Yosemite National park. Another stop in Squaw Valley, and a final push to my brothers home to Temecula, CA. 8500 road miles, averaging right around 300 miles a day. Approximately 1500 miles of "unimproved" roads. Should be a nice little trip.

-edit-
Actually, I'm going to start a new thread, and end the hijack here.

Man! If I ever found myself unemployed, that's exactly the type of trip I would take. Unfortunately it'll be another 12 years before I get that much time off in a row at my current employer. :roll:
