Bloody hell Simon, how the Devil are you? Been a long time but good to see you are still in the Land of the Birds
Differing opinions re your question (isnt there always?). Most peeps I know who have used the Jaws springs/spacers say it's marvellous, just a few I know have said they're not.
Some have splashed out and put Ohlins in ....the difference apparently is fantastic. ( I tried aj's Bird withnew Ohlins F&R and 'twas like riding on a Maglev)
Me, Ive put Hyperpro progressive springs in and even though one or two
suspension gurus say its a waste of time I notice a marked improvement.
However...back to basics. How old/mileage has your Bird done and when did your forks get a good overhaul? A thorough strip, clean and rebuild with new oil will make an immediate improvement.
Anyway, nice to 'see' you after so long Simon.
