Progressive suspension front springs help wanted

Now I got the Progressive Suspension from springs (11-1145) and also the preload adjuster for my curvy model 2001 registered on 2002.

Went trough the installation instruction.
Generally the preload required is 3/4 ->1" 1.9 - 2.54cm OK
Calculating the spacer length if the fork cap is longer than 1" which is the case with preload adjuster (those are in garage so i can measure them right now) Instruction. On pics the spring with the spacer levels to the top of the spring housing. If i deduct the extra length that the preload adjuster brings and shorten the spacer it will be OK?
Oil level seems to have changed 2001/2002 2001 104mm and 2002 115mm. I take that mine is 2001 since i have to buy the preload adjusters.

Oil i habe 15wt but the original is 10wt.
Myself i am 90-94kg of a rider.

Any hints from experience?

Cheers

Trim the spacer so that with the fork legs extended the washer sits level with or just above the top edge (NB THIS IS FOR THESE SPRINGS ONLY!). Put it together and try it out. Trim off more rather than less spacer - you can always trim off more. Make sure you cut them equally.

Although you say you have progressive springs I've seen them in three flavours, some are two stage,some three and others true progressivly tightening, which do you have (Oh and Progressive is also the name of a company making all of them).

I'd disregard the spacer length info and workout static sag (checkout racetech's web site/or do a search) to get the spacing right, the preload adjusters should be about halfway out if you want to use + & - on them when you do your calculations.

I wouldn't worry to much about switching between 10 & 15 weight oil, as to levels, I really can't remember, but take the K2 air gap.

Cheers Mark.

Even with the preload adjusters?
They are significantly longer than the cap and will go much deeper in.
With those i can do some adjustment without removing the cap.

Hmm, I have Progressive springs on a 1999 bike, not sure of the model no. though. Wind the adjusters right out before fitting the fork tops. Give it a go and measure the sag, then if the adjusters don't have enough range, trim the spacer tubes. I'd use 15W or 20W oil for your weight, stock air gap.
