Adjusting rear shock?

Need some help from the forum members. As I understand it Triumph went with two different rear shocks on the 900 in MY96. Earlier models (same year) are adjusted on the shock itself. Later models have a spring tightener screw under the seat. Mine is an earlier model with the adjustment on the shock. How do I adjust the shock for two up riding? I would like to increase the preload a little anyway and more so for two up. Looking at the shock I can see an adjustment collar. Don't know what it does and getting at it looks difficult and what do I do with it if I could get to it? Haynes manual not very helpful as it's only recommendation is to consult Triumph or a Triumph dealer. I figure you guys and gals know as much or more than any dealer so here I am hat in hand needing some advice.

Thanks, Rick

Figured it out. It is an aftermarket shock of unknown brand. I'll take it out this weekend and either add a heavier spring or replace it completely.

I changed the original rear shock with a Wilbers shock last year, and its a totally new bike to ride. I got the shock pre set to my weight and rider style. But if you put on a stiffer spring in the rear end, you just have to replace the front fork springs too, or the nose dive will be too much.
I put in wilbers progressive fork springs at the same time, I could gone with an even stiffer spring in front, but its much better than original. Even with two up and full luggage.

Thank you. Very good point. I weigh 230 lbs and the rear shock is nearly at it's preload limit. The front is a little soft not terrible but I understand your point about the relationship of the two. I'll address both.
Thanks again,
Rick
