Thread: How to shim valves for sr20ve

Interesting, how would you go about checking the lash for the high low when it is constantly in contact with the rocker pad, sort of like Honda's loss motion system?

I don't think the factory specify checking the clearance for the high lobe base on what I have seen from the FSM.

LOL... can someone explain to me how to adjust the small lobe lash independent from the large lobe lash? lol

Saw?

I know how to change the lash from the large and small lobes.... but it has nothign to do with the rocker arm...

Typically with feeler gauges.

I will probably build a tool to push down one valve at a time that way I do not need to remove the cams. I would just push the valve down then grap the shim with a long magnet meanwhile the other spring will be holding the rocker arm up out of the way.

On second thought I dont know if I want to use harley shims. My car may suddenly break down or start leaking for some totaly unrelated reason.

Ok, I was hoping for more details.

Using a feeler gauge is a little basic for me.

Very true

Don't worry about using using the V-rod shims. The V-rod is not a traditional(push rod air cooled) American engine. The engine was design by Porsche. That's why the shims are in metric. You're good to go.

What I do is engage the VVL "latch" (for want of a better term) with my finger, and then push down on the high lobe rocker with a large flathead screwdriver. With the right amount of downward pressure it'll hold the latch in against the spring.




I'd like to know too! In the post you quoted, I said how to check the clearances for the two lobes independently... adjustment is something else!

Well, your original post makes it sound like you could independently adjust the lash between the high lobe and low lobe. That why you went through the trouble of checking the middle lobe clearance.

As you have found out, you can't.

By opening up the clearance of the middle rocker with the high lobe, you will also open up the lash for the small lobes. They are tied together. The only way to adjust them independently is if you regrind the base circles, not something you could do with a feeler gauge.

Keep in mind, if you open up the clearance between the high lobe and the middle rocker, it will be harder on the valve train and results in a louder running engine.
