Default Red Line 42904 V-Twin Primary Case

Who has experience with Red Line 42904 V-Twin Primary Case for Tri-Glide's?
I have recently (2k miles) change to Red Line 58204 Heavy Shockproof in the Trans and really like it. Wondering if the 42904 in the primary would also be a good choice.
On two wheel 96's we ran Red Line exclusively but did not have these kind of temps that the 103 has on a Trike.
Any experience would be appreciated.

Im curious if the redline in the trans helped, or hurt finding neutral? Seems to be a real problem on the 12s! Mine only has 2000 miles so don't know if it gets better or worse from here?

It really helps find neutral. I almost never have a problem now getting to N as a matter of fact you really have to pay attention when taking off that you do not hit neutral when trying for 2nd. Quiets a bit, but Harley always will clunk to gear.

I run RedLine in engine & RedLine Shock Proof in tranny. I tried RedLine primary & my clutch started to slip. I went back to HD Formula + & never had anymore clutch problems.

In my Streetglide I ran royal purple! Seem to work ok? Other than ordering one quart of redline for trans is there a local place, parts store etc.. That might carry it?

Everyone has their favorite. In answer to your question I have used RedLine Primary for years in all my bikes with no problems.
