im getting a lot of dive on the front end when i brake hard .on my gixxer you could adjust it on the bottom of the fork leg. were do you do it on the 999
The technique for checking the front forks is to put a tiewrap around one leg and push it up against the oil seal. Then go for a ride and when you stop you will hopefully not have the tie wrap right at the bottom. If it is right on the bottom of the leg then you have run out of suspension and need to sort the preload (big adjuster nut at the top). The RATE of dive is controlled by the compression though, which will be on the bottom somewhere.
if it's like my 1 good luck, I think it's the spring, Ive tryed the rebound,it helps but the forks go down in the end, I think I need a more progressive sping but I will try to adjust it for a bit longer befor I pay out for some springs
