Firebrand forks air gap?

My 2000 firebrand forks are weeping, anyone know what the air gap should be when refilling the oil is? Also what weight of oil I should be using?
2000 rrx model forks I'm sure!

7.5 - 140mm

Have a search as it's been covered before with a few different recommended variations.

Er correct me if I'm wrong here chaps but Grumpy said they are Blade forks RRX ???

So the air gap may be different...

"Firebrand" I blame predictive typing...

So it might be a question better placed in a 'Firebrand' forum

You need to check the air gap in your head, Stuart, Firebrand ffs

Having played with various air gaps on USD Blade forks I've tried some internet-recommended air gaps, the opinions on various forums seem to vary quite a lot, and not much consensus.
I tried a 90mm air gap but it's like riding a road drill, 110 seems ok but I haven't yet tried 120mm.
I've been using 10 weight oil throughout.
I'm currently using 9kg K-Tech springs, gold valves, 110mm gap and 10 weight oil.

But I expect with a bit more playing about it could be improved a little.

What I don't understand is why people don't just try different settings- how long does it take to whip the wheel off, mudguard and legs, then drain and refill with another setting?

That way you end up with something that suits you and your riding style,useage etc, not to mention body weight.

For example, i like to sit forward, keeping lots of weight over the front end. It works for me, but other riders prefer to get their r's back on the seat, and keep weight over the rear. You'd benefit from different fork setups- quite a bit of difference actually, with both choices.

I spent a weekend draining and refilling rwu Storm forks five or six times to get an air gap that i liked, then tried different weight oils at that air gap.
Time well spent.
But then I sold them and stuck on some Blade USD ones, back to square one....
