How to adjust Spring Preload - Rear end 82 750J Maxim

SO I have my owners manual in front of me.

I wanted to adjust my shocks/ride for a test ride with my wife on board (first time).

My damping force (top adjustment on rear shocks) was already on 3 which is the suggested number for passenger with luggage installed.

My spring pre-load should be C-E. As best as I can tell it is on A. I can't figure out how to adjust it. Do I insert an allen wrench into the boss that is stricking out and spring the lower end to C? The manual has no info HOW to do it, on what to set it as.

I'll search thru the Haynes while waiting for a response.

 

you want to get some oil on the collar first then get something that fits the hole in the boss nice and tight, if it's loose and slips out it'll bugger up the boss, there is a tool kind of like a big spanner wrench but a screwdriver cut off to about a inch stub works
put it on the center stand, wrap a rag around the spring, grab the ends of the rag , pull up on the rag and twist the collar, don't lean on the seat

 

I'm finally gonna get around to this, this week.

Unfortunately it's cold and dark and wet out now.

My maxim has the solid looking shocks w/o exposed springs.

Hopefully it goes smoothly Wed or Thursday and/or others have more tips.

 

The "solidness" is just covers. Underneath is the same "ramp" preload adjuster as any other shock.

If they're calling it A through E, fine, most standard shocks have 5 preload positions so that makes sense.

On all of my bikes, which encompass original Yamaha shocks, Progressives, and 30-year old aftermarket (Mulholland) shocks on my Norton, they all adjust the same direction: Clockwise (viewed from above) increases the preload. And not in little "clicks" more like big "clunks." You'll be able to tell, trust me.
