my 09 stays at 230 consistently....

 

Like I said, I have had the stage one download since last March when i bought the bike. Thats 7 months with no issue using the download, and that was during the hot La. summer. The over heating only started after the oil and oil filter change and the trans fluid and clutch cable change that i did the same day before riding.

 

For this you understand that i'm referring to a K&N oil filter, not there air filter. I don't think an oil filter would lean out the mixture?

 

Changed out the k&n oil filter and put an hd brand back on Fri, rode all weekend with no heat issues and might be running a little cooler with the amsoil than the syn 3 but all i know for sure is that all weekend the bike did not start to go into over heat mode.
Could have been a bad k&n filter or the dealer at the Harley store said it could have been an evo filter? It's fixed so I'm happy, thanks for all the help and suggestions.

 

No top grade oil made these days under normal conditions breaks down after 3k, and for sure not any syn. Even HD360 regular oil is good for 5k changes as hd states in their owners manual. If who makes it is the reason to change then do it, but the rest of that info IMO is straight out of a male cows rectum. LOL

 

once again peppi.. you da man!

 

Syn 3 ain;t no true synthetic,MMMMMOOOOOOOO.
I used it for a while and went 5000 miles once on it, did a oil change and the plug had gunk all over it. Went with Amsoil for 9000 miles, no gunk. MMMMOOOOO.

 

Syn3 is not a Pure synthetic. Many Oils are hybrid, partial syn, partial dino oil. I have read many reports and all of the rate Redline, Amsoil or Mobil VTwin as top of the line. They are all pure synthetics, 100%. Syns carry heat and help dissipate it quicker, and they have far higher flash points, the point at which they begin to fail. I'm sure no expert, but have wrenched for years, and don't think the oil itself is the fault of excessive temps. Easiest way to eliminate the oil, or solidify it as the problem, is to change it all back the Syn3 and see if it changes anything. Drain the oil back into something clean if you want to try and reuse it in the event you find the oil was not the culprit. The filter tho will just have to be replace every time you drain the oil. If the oil change makes a difference, its a cheap fix.

I'd speculate its in the computer, one way or another.

 

Heat is the main factor in oil breakdown. Even a good non synthetic oil will break down under stop and go traffic to a point that damage can result. Synthetic will stand more heat before breaking down. I wouldn't use SYN 3 if it was free, it's a blend of fossil oil and man made product.

Item (1) is a Group IV base oil. unable to locate the manufacturer of this base oil. Group IV and V base oils are the only "true" synthetics to the cognoscenti.

Item (2) is probably their additive package (boron, calcium, magnesium, phosphorous, moly), but it is conceivable there could also be some "secret" synthetic oil, maybe an ester type oil, included in it.

Item (3) is a fancy name for synthetic rubber (or elastomer) but this is probably considered to be "synthetic" oil as well.

However, Item (4) is a Group II base oil, namely Conoco Pure Performance Base Oil, either 110N, 225N or 600N. no one is calling a Group II oil a synthetic.

No information on the group number of Item (5), but it is Conoco's Cit-Con 650N Base Oil. It's presumed that it is a Group I oil as it is solvent refined. Most quality blenders are not using Group I oils in their premium motor oils and they are not considered synthetics.

(From the MSDS for the HD 360 20w50 oil: The major base oil constituents in it are the same ones as are listed in Items (4) & (5) above.)

I think the Items (4) & (5) above, are to keep the old air-heads running without bearing skid and gasket leaks. Good for them, but not for us?

Harley-Davidson talks about SYN3 in their advertising as:
"Developed with a proprietary blend of three synthetic base stocks, ..."

Or not!?!

Since there are significant amounts of Group I and II oils in the SYN3, could the MoCo have stretched the definition of "synthetic" a bit further than Castrol did when changing Syntec from a PAO Group IV base to a hydro cracked Group III base?

Exxon/Mobil (Mobil 1 synthetic) lost a lawsuit trying to go after a few oil companies for advertising blends as full synthetic. Mobil lost, and now the oil companies do not have to disclose on the label it contains Group I, II or III base stocks which are all petroleum based.

So it is legal for Harley to market syn3 as a full synthetic, even though it is only 60% synthetic and the rest petroleum based.

 

Like I said, Syn 3 is not a pure synthetic, but rather a hybrid. I don't care what any court allows them to claim in their advertising. Any way you look at it, that is false advertising.
