15W Fork Oil. Does it make that much difference?

Best way is by measuring the air gap at the top to make sure they're both even.

You need to be careful showing that picture because the air gap and oil levels are different for forks without adjusters compared to ones that do have them.




98/99 models (without fork adjusters on top):
475cc oil
121mm air gap


00-03 models (with fork adjusters on top):
465cc oil
132mm air gap




Just for the record, i am of the opinion that the fork adjusters do absolutely sod all.
When i had them on my forks they were always screwed right in to attempt to firm up the front end but with little effect.
Due to another issue i changed my forks for an older set that didn't have adjusters on then put the 15w oil in and there was a very nice difference as far as handling was concerned, and it was so suitable for me that i just didn't bother swapping the adjusters back over.
If you ever change the fork oil then upgrading to 15w is a small mod that i would totally recommend without any doubt, that can improve the front end handling of the bike for no extra cost.
