Valve Adjustment Notes

Good for you, Sprite. The next time you will complete the job much faster, since you are now more familiar with the entire procedure.

I find a soda straw in the spark plug hole works really well to judge what stroke your on as well, you can see it rise all the way to the top on compression and you know your at TDC. Get the flexible end type and bend the top at an angle to prevent it from falling all the way in. The rocker arms should "wiggle" a small amount when you rock them side to side. This is how I check the Guzzi valves without pulling all the rubber plugs to find the index mark.

Shifting to a high gear and using the rear wheel (on a stand) also makes it easy to cycle through strokes.

The timing marks also look like a good technique.

Here's a good video of how each stroke works for those who are curious or don't know already.

I say this with all respect: Atta girl, Sprite! Good for you for jumping in and taking care of it.

Way to go Sprite. And for future reference, I'm retired and have plenty of time on my hands, so would be happy to help any time you have the need.

One of my intakes was leaking turns out you can install upside down.

And you can't swap intake cover for exhaust cover if memory serves me right. I marked mine before I took them off the first time, always put them back on according to that and they have never leaked. rj

In addition, eventually the O-rings will harden, leak oil, and need to be replaced.

I thought both valve covers were identical, but I guess not. They definitely can be installed upside down. The bolt holes are oriented different on each side.

How many have found that their valves were unchanged from their previous adjustment? No adjustment required.

With 14,000 miles on the odometer, I have adjusted the valve lash about six times. Perhaps once the valve lash was unchanged from the previous adjustment. That's why I check the valve lash every 2,500 miles, as originally specified by CSC.

That's normal. There is no smooth cap on our plugs. It just sits on the threads.
