Lovely yellow paint job there!
The reason why I and many others opted for 15W oil is to increase the damping response. The Guzzi spec of 5W to 20W is a huge range. The reason for adding more oil is to increase the air-springing effect as the forks near full compression, not to affect the damping. Adding an excessive amount of oil could ask a lot of the oilseals, but reports of up to 500cc being used make that volume sound OK. Just the same I'll stay with 450cc.
Reading this thread reminds me that since my Breva is just over four years old it's time to change the fork oil again. One wet day in the near future looks like the go for that so I'll buy some oil. This time I'll try to measure the oil level after adding 450cc of oil to one leg and match that for the second leg because that method is preferable to measuring just the volume when refilling after an oil change.
As an experiment I tried 500ml of SAE10 fork oil. It didn't work as the front end was wayyyy too harsh - so I took the front end apart and went back to 450ml. Haven't had chance to ride it yet, but I've got my eye on one of the Matris FM100KE kits if I'm not happy......
I've got a feeling I won't be....
