I'm having issues with this rear shock because the seal head apparently has a retaining clip on top of the head and the bottom of the seal head, can't get it out. Also the seal head from All Balls was wrong even though the package states that it's for my bike and year. The shock shaft is "NOT" a 14mm shaft but a 12.5mm shaft. WTF really !!! I guess they weren't supposed to be serviceable .Any help would be good.
The Shop
I measured everything up, and then removed one 1mm shim from the left side of the governor (see pic above) and put it on the right side of the spacer. This effectively moved the spacer that the linkage fork sits in over 1mm. It made a 5-6mm difference to the height of the linkage going up to the power valve. This "lengthens" the linkage and brings the groove in the linkage anti-clockwise back to the hole in the case.

Also, i get my spokes zinc plated. Its cheap and gives them the OEM look. In fact, grab all your hardware, chain adjusters, axles, nuts and bolts, everything and take them to a zinc platers and get the lot done as a batch. Bike will look like new and cost is minimal.
You will probably find that your puller is an 18mm x 1.5 pitch
So, i played with the shim stacks on the governor. It only takes moving a 1mm shim from 1 side of the groove that the linkage sits in, to the other side to make a massive difference to the linkage. As you can see in pic, you need to align the slots, so that your powervalve is in the correct position at idle and then slowly gets pulled down (linkage moves up turning power valve anti clockwise a few degrees). By playing with the shim stack, you can get your linkage back to where it should be. This worked perfectly on both my bikes. I have not even bothered using the new linkage.
If eric decked your cylinder, it will affect the linkage adjustment slightly, but you do have some adjustment on the linkage. Make sure you governor is in good condition, bearings, shims, spring etc, as any slack in that will get transferred as slack in your linkage.

This is the damage .
You can run separate covers. If they were sold in pairs then no, but as separate part numbers, no problem. I have several K and L engine case and i pick and choose between different ones. As the bearings are an interference fit, warm the case up in your oven and then gently tap out all your bearings.
Below is a pic of some cases i picked up. Have a look at the left hand case which is the same as yours. It has been welded where one of the gear shafts fits in.
