[bradders]

have been out today and the cable tie I fitted is right at the bottom. I know its not sliding down, you can see where the slider is going to, I am just using all the travel!!

so how do I sort this? bike seems to ride well, and is super planted even on the bumpiest roads, but need to get some travel back, so is it up the preload, or stiffen compression, or both?

there is too much sag, so I will be upping the PL anyway, just want to know if I need to do more

thanks

Stop using the front brake

Stop trying to keep up with me

Get a slipper

Hope you had a good day and you've left enough tread on the tyres for Germany

cheeky...both of you constructive, helpful comments always welcome too

set of diablo sc2's going on tuesday...1 qually session on a british ssport bike for a bargain price! cheap enough to chich away iof needed when we get back

i dont think it would be of any surprise to suggest you may need bigger front springs.........but why not try a turn in on both the front pre load to see if that helps....

[bradders]

yep, thet'll be the first go, get the sag right. Then see how it goes from there. Trying to see how good I can get it before I spend money...as cash on mods means less cash on fuel!

[NBs996]

yeah sorry me old mate.

Thing is though, when you're transferring a lot of weight through heavy braking, to stop the forks meeting the stops you'd have to firm up the springs/preload. Then this would have an adverse effect on the damping over bumps.
Not sure you can have it both ways so i reckon leave the springs in and firm up the preload a bit, and don't brake so much... braking only slows you down anyway!

at my speed I dont have to brake to much anyway havent been too heavy on the brakes, no more than normal and not as if track riding

Adding preload to the spring will not stop it bottoming out, all it does is change the ride height and stops the initial high speed dip on the nose, the spring will still compress the same distance wether you preload it or not.

If the springs are the right weight for your given weight then decrease the air gap by adding more oil, but before doing any of the above, check that the sag is correct first.

cheers, saw your other post...

I'm going to set teh sag right then dial in a couple of comp clicks see how that goes. Its a great bike to ride tho, the front end is spo planted I just want to ensure I dont do too much damage with my ham-fisted attempts at setup!!
