I just picked up the Redline oil package, 4qt. 20w50, 1 qt. shockproof transmission oil. 1 qt. primary oil, and changed all 3 holes. Question is, the primary oil seems to be VERY thin, compared to the Syn 3 that was in there. Any pros or cons to the Redline primary oil? I cant tell the difference after a short road test, looking for any long term usage feedback. Thanks.
The V-twin primary by Redline is just their MTL and yes it is a full SYNTHETIC and wet clutch approved...
The label you use is costing you about 3$ more than the Yellow MTL... Read on the Redline site and you will read it is the same...LOOK here;

I use
20/50 for the engine
MTL for the primary
ShockProof Heavy for the tranny.
Did you know that the tranny gear lube with ShockProof DOESN'T allow Metal to Metal contact... NEVER a piece of metal on my magnetic plug EVER..

I used MTL in my 2000 FXDS Built big, using ORIGINAL clutch and put 117,000 miles on it. worked great when sold. 100,000 on the 6 speed using ShockProof... Never any problems...
Just looking on "their" price sheets and it is costing the same.... Look at other places to buy and you can save about 3 to 4 $$ a quart..

The Red Line Primary fluid was causing your clutch to slip????? Haven't heard that one before, and a lot of folks using that stuff.........I'm surprised!

I am a big supporter of Redline in tranny and primary....however I have since switched to the new synthetic tranny/primary fluid put out by harley....I have an08 ultra with 90,000 and for the longest time it was having an issue with finding neutral and even though I adjusted clutch many times I just couldn't figure it out....dealer looked at it and adjusted and nothing. I tried the new fluid at the start of the 19 season, and the neutral problem went away. shifts are way better and finding neutral is excellent. Just had the entire primary off to do a belt replacement and check front pulley. Primary fluid was good and clean, no shavings on the magnet. There are those that say they would never use it but since it is a Harley product I have no issue continuing to use it. Some feel it is expensive but I feel that it helps my bike ride right.

I was a bit put-off by the $20+/qt for that stuff. Perhaps your experience suggests it is worth it. Besides the price, I noticed that Harley now uses 75-140 in the transmission. I have always been comfortable with that and didn't know why so many use 70-90 in their transmissions.
