I am a petite 6' and 265lbs and do have a full windscreen on the bike. The progressive springs are now on my want list but being retired it may be awhile before I can come up with the $$$.

Thanks for the info.

I replaced the stock 10w in mine with fresh factory spec oil and the difference is amazing. you should really check your steering head bearings as well. Ehey can definitely cause the problems you describe as well as the previous suggestions offered,

I have used ATF as well and it is usually 10w as well.

If you see it on my bike I did it

When you say that people use transmission fluid, do you mean like Decron 6 or ATF 4? Is one preferred? I put Belray 15w in mine, but I am trying to be as cheap as possible this go around.

Used atf in mine, forget exactly but probably just Dexron 3, store brand even. Almost any atf should be fine, there's no clutches or bands to worry about. That original fork oil smelled horrible, like dead whale or something.

Bike shops didn't have any lightweight fork oil. Atf is supposed to be 20w I think.

I’d still use Bell-Ray 10w. Some things you don’t need to scrimp on, and to me fork oil, which you likely won’t have to change again, is one of them.
If you have a heavy windscreen, maybe 15w.

As an FYI, there really is no standards for fork oil. Some ATF is actually heavier than others, so there’s no definite “weight” between them all, and that goes for dedicated fork oil. One brands 10w might be another’s 7w.
The reason I always recommend Bel-Ray is because it’s become that standard to go by and thus much more predictable.

I also installed Progressive fork springs, and a fork brace, which I think improved greatly the Vulcan’s front end.
