DL1000 fork oil question/theory

I posted this over on the VSRI, but since the gene pools are slightly different I thought I post this here too.



I'm not happy with the stock dampening effects on the stock forks of my 07 DL1000. They seem to have a very harsh initial dampening, but get better with a harder hit; IE, deeper in the stroke. The rebound seems to be okay. It's just the initial hit, like most road imperfections where it gets dicey.

I will leave the spring rates and fork braces for another discussion, since everyone seems to agree that it's too soft.

I've read and spoken to other big strom riders that have switched to a 10w fork oil with mixed opinions. AFAIK, stock oil is 7.5w.

My question/theory is actually switching to a lighter oil. Say 5w or even 2.5w, which AFAIK is what is used in most cartridge type of forks. That would allow the oil to move more freely through the valving in the problem area of the stroke. Yes, it could have a negative effect deeper within the compression stroke and in rebound, but since I ride mostly on the street, those areas are used much less than the first couple of inches of the stroke.

Any knowledgeable opinions?

Oil level/ air gap

I'm not a suspension expert by any stretch, but you might try taking alittle oil out of the forks to increase the air gap (air spring). this may help the jarring alittle. I did the .95 springs and the gold valve thing with 7wt oil. it definitely made a difference, but I don't think I'd go as far to say that it was night and day yet. haven't got enough mile on yet this spring to evaluate much.

I came across this info on suspension tuning a few days ago. Lots of info on oil, springs, etc. Maybe you'll find it helpful
