SP2 swingarm alignment

When installing an Sp2 swingarm, should the pivot bolts be screwed into the frame equally on both sides?
I noticed when fitting that the left bolt went in a lot further than the right but none of the guides / manuals specify exactly how they should be adjusted...
I've just re-riveted the chain and want to make sure everything is correctly aligned.

Anyone able to shed some light on this?

TIA
Stu

Stu-

You want to adjust in on each side until you have contact evenly on the conversion sleeves from both sides.
This should put the bearing bosses equally positioned between the frame and engine cases. Double check back and forth as you adjust and turn the adjusters in.

The swingarm pivot adjust bolts will apply force through the bearing collars and onto the engine cases. The bearing collars are what centers the swingarm axially with the engine cases.

The right swingarm pivot adjust bolt is torqued and locked first, as that's where the pivot ball bearings are located to position the swingarm and control axial and radial movement.
Then the left pivot adjust bolt is torqued using the swingarm pivot bolt, and then locked.

It's all in the procedure in the service manual.
What might occur is the pivot bolt may be corroded and hard to remove if it's never been removed before. That was my case.

I used a rubber mallet and drift punch to gently hammer it out, then cleaned it all up and applied grease to the bolt prior to installation.
Had to clean up the adjust bolts as well.
