I have to be honest, I am still suprised at the controversy over the fluids needed and used on everyone's bike's. I just figure they must make grear oil and tranny fluid for a reason!!! I am not suprised by the many various brands used or talked about here but I am suprised at the various weights used. What wieght is it that Harley uses and recomends? I still can't even get an answer for that. I am not going to say anyone is wrong but I do ellect to use gear oil in my tranny. I am also going to try to locate some Red line and start out this spring with that in there. If I don't like, back to Amsoil I go and there I will stay.
I just put redline in my trans over the weekend when I changed the clutch cable. The guy at my local shop swears by it. Only thing it was pretty thick going in. Maybe it was cold from sitting in the garage or is it always like that. Need to check on that.
I just switched to redline with shockproof and it was thick as hell going in. But I love the improved shifting the reduced noise and neutral is like butter. I read alot of posts before trying it and had a local indy shop tell me to use it and I am happy so far. I switched to Redline primary fluid also. Still using Mobil in the engine for now.
The service manual says to use
Formula+ transmission and primary chaincase lubricant.
I am putting royal purple max gear ( 75W- 90) in the tranny.
Is this gonna be ok for the primary?
Ultimate goal is to use RP for all my bike lubricants.
I talked to an experienced hand, and he told me that doping the threads is a carryover from the days when the Harley O-rings were junk from a low bidder.
