RE: Forks
Thanks, I have the manual - doesn't say anything about fork oil change, - probably cause it's so easy.
It's only taken me more than 2 years to work out how to take my visor off my helmet.
I'll get some oil. When I replace it, I will leave the tops on at the start, measure what comes out, I'll have the bike blocked up and I'll do it on the neighbours front lawn as not to make a mess.

RE: Forks
Though 20 wt was suggested, I would caution you to use that heavy of an oil. Most fork oil is either 5, 10, or sometimes 15 wt. 20 is really thick and could cause the forks to lock, which is worse then having them soft.
Remember that in a corner you are using a multiplier because of the fork to ground angle when you are leaned over. So 400% increase in static oil thickness could multiply out to over a 1000% or more with the lean angle. That would be like having no travel at all and hitting a bump mid turn could have a serious negative effect.
Since the recommended weught is ATF (which is effectively less then 5 wt) I would start at 10 and see how that works for you.
Depending on how much you want to spend, racetech makes1.0 kg springs and both compression and rebound cartridge emulators for the 1000f. This is really the way to go for the best possible solution.
With those installed you can experiment with different weight oil to really dial the front in.
Oh and don't forget the rear. It also effects dive and how the front feels too.

Yer ... the 20W is the absolute limit ...
As I mentioned trying the 10W is what Mark should do to start with ..
He is trying I think to stiffen up his ride while avoid the cost of new progressive springs...
I have never tried it myself, but I have read that 20W does work , but yer , a last resort

RE: Forks
I brought some 15w oil, mechanic recommended it, he said start there, and you can then chosse upor down afterwards.
he said to add spaces into the forks, or replace the springs.
he said try measuring the travel, take 20mm off and that should be the thinkness of the spacers, maybe I should just buy new springs

RE: Forks
Yer ..15W should be a good start if you want to firm up the ride Mark
Dunno about the spacers though ..?? I know some guys do that , but I think if the oil does not help mate , that a new pair of progressive rate springs may be easier .. and a better bet ..
I am not too sure what they cost here ..?
