clutch slipping
07 Streetglide, I switched from mobil 1 v twin 20-50 to dexron atf fluid. My clutch didn't feel good with the mobil 1. Well after whe switch I went riding and it seemed fine for a while,( about 2 hours riding) then the clutch started slipping if I put a good load on it.
Anyone else have this problem with ATF ? I have a feeling it may just be out of adjustment.
I dont think the fluid is causing the slip , either adjustment or plates are bad.What do you think?
Byu the way I have 13000 miles on it.

Most likely cause is adjustment. If clutches are just on the edge of being out of adjustment, they usually work well when cold and once everything expands when hot, they tend to slip. Plenty of people here are running Dexron or type F with good results.

Yes, I had the exact same thing happen. I have readjusted the clutch and it is not slipping anymore. I'm not sure about ATF yet. It felt good when the clutch was at the setting where it slipped. Now it seems to grab in two steps. First when Leaving from a stop, I let the clutch and it feels pretty normal as I'm taking off, then it seems to grab again when the clutch is let almost all the way out. I'm sure what is going on is that it still slipping just a little with the clutch leaver 3/4 out and then it grabs that last little bit when I let it completely out, but it is taking some getting use to and I'm not sure it is something I want to get use to.

I just dont get it....why use ATF or mix it with something else that was in the primary before you put ATF in. Friction Modifiers or other additives contained in these fluids affect the clutch friction disc material. Who has extensively tested these fluids and verified their compatibilty with not only the lining material but other components in the primary..like the glue that holds the magnets on the rotor, affects on the chain and bearings?
Saving 4 or 5 bucks per primary fluid change is not worth the risk to me.

Do automatic transmissions in vehicles not have the same wet type clutch packs and similar electronics (sensors/switches/solenoids) in them? They have run countless miles with ATF. Bottom line is you need a little lube for the chain and roller bearing in the primary. The rest is for cooling. If the rotor/stator can survive engine oil or Formula +, I think it's reasonable to believe that they can take ATF as well.
BTW, ATF (especially type F) is designed to work with wet clutches and therefore doesn't have the "friction modifiers" that everyone screams about when trying to say car oil won't work in a motorcycle. Again, FWIW and YMMV as always....
