So my M2 started sputtering - carb fart at around 3K pretty bad. I noticed that the idle changed a lot when i pulled off the plug to front but very little for rear cylinder. Also there was a time when there was a lot of ticking come from the head.
I changed the intake seals twice and checked for leaks - none that I could find. so I pulled the heads just to see, the valves do not leak - heads where done about 3 years ago. Swapped plug wires. I am wondering if I have bad tappet causing intake not to open all the way ? anyway way to tell ?

I'd change the plugs first.

Then I'd run a couple of ounces of clean tranny fluid through the oil for 100 miles or so. Then change the oil, run it for another 100 miles and change again.

Keep us posted.

Sounds like what my ironhead does when the points are fungled up and lopsided.
It may be worth a look at your timing cup/sensor.
Perhaps something obvious&easy in there?

Did you do a compression check?
