Changed over primary oil "plus"
« on: April 06, 2018, 04:35:42 PM »

Checked the primary chain tension the other day and found it to have gotten tight again so I did my oil change over a little sooner than expected. When I drained out the oil and removed the primary cover all seemed good. No side movement on the clutch hub or comp. no bits of bugs in the oil just the normal clutch paste.

Changed to ATF synthetic with some ATF Lube Guard Premium.
I noticed a difference straight away. No clunk going into first just a quick click and "N"  is a just a slightest tap to slip in and the clutch drag is all but gone.

Today I was out and started to hear some whining from the primary. Thought to myself that's that chain noise.
I got home and pulled the dobie and sure enough the chain was tight again.

The only thing I can think of is the motor gets a little cranky on starting up sometimes and misfires, not sure why, but I think the misfire allows the adjuster to move up.
Whatever the case I've now ordered up a Hayden M6 BT07 tensioner and get rid of HD stock tensioner.

Other than that the ATF synthetic has made an improvement on clutch drag and shifting so far. I'll see how it goes after I get some miles on it.

No, but it works quite well with wet clutches (automatic transmissions have several internal wet clutches).  I've been running it for many years in my Harley without issue, and as noted in the OP it does improve the clutch drag problem significantly.  Harley only recommends fluids they sell, so just because they don't recommend it doesn't mean it won't function well.  Remember, for many years they also recommended against using synthetic motor oil, implying it would cause bearings to skate and gaskets to leak like a sieve.  Magically they changed their tune on synthetic motor oil the same day they started selling SYN-3.

X-2, Compensators need at least a GL 1 ( extreme pressure )rated lube. Formula plus is GL 3 , Redline Primary fluid is GL5 . The "old " 05 & prior compensators didn't care what you put in because they got oil   As we all know the '06   and later compensators  get virtually no oil and what little they do get you want to be at least GL1 rated, not ATF.

The "old " 05 & prior compensators didn't care what you pit in because they got oil   As we all know the '06   and later copensators  get virtually no oil and what little they do get you want to be at least GL1 rated, not ATF.


The compensator was a concern so in my research of ATF I found the following product would help give the compensator the lube protection

http://www.lubegard.com/~/C-304/LUBEGARD+PLATINUM+Universal+ATF+Protectant

Along with the synergol performance results

http://www.lubegard.com/SynergolTMS.aspx#

As stated the stock compensator is starved of sufficient oil to begin with so this product should help prolong it's life.
I've had my compensator apart and it's in good condition, no ridging of excessive wear just smooth shiny contact points.
I'll give it till next oil change (if it makes it that long) and see how it works. If it's no good it's not a big deal as I'd have to be changing the comp at some point anyway if I was to carry on using the recommended 20w50

It's been over a month now since the change over to ATF synthetic with ATF Lube Guard Premium in the primary.

I find it to be working well. Putting it into first gear is much smoother just a click instead of that heavy bang plus no more forward lounging from clutch drag.
The compensator and clutch are stock from 07 with 21k on them.
I'll see what it all looks like when I pull the primary case off at the next 5k oil change to do an inspection.
I've been told I could go as far as 20k before changing the ATF. Don't know, but don't much care for the idea of that much more clutch muck building up in the oil. Think I'll stick to the 5k change anyway.

Good idea to change primary oil at 5k, lots of particulate there.  Will be interested to read your report on the ATF and on your new tensioner.
