1. Harley Davidson does not recommend ANY Jaso rated oil. Harley recommends for their engines API CH or higher oil in their new bikes.
2. After a quick search Indian requires an API SM oil, no mention of Jaso.
3. Most metric bikes require Jaso.
4. All the above as far as Harley goes is for engine oil. For the primary I would use Harley products or to be safe something stating its meets Jaso MA or MA2 and Jaso does set the standard for oil friction requirements for wet clutches.
5. Jaso rated oil can be any weight oil that meets Jaso standards much like API oil.
6. The Jaso standard is just something to make you feel safe if in doubt and concerned about a wet clutch, however interestingly I do not THINK Indian states anything but API SM.
Yes they say to use a C rated diesel if HD 360 oil is not available. They also state to change back at the first opportunity to 100 percent HD oil. Only use non HD C rated oil until you get to a dealer to get HD oil. HD primary oil is a 20-50 oil. After market 20-50 oils are fine. HD transmission is a 20-50 oil. Gear oil is a 20-50 oil. So using a gear oil is fine.
Harley only recommends Dunlop HD tires. Will you only run HD tires?
You confirmed in the owners Harley says API C oil is fine, not sure what the conversation is about. Of course they think their oil is best but still still you that API C rating, like Indian gives you that API SM.
I don't disagree with the Primary or Transmission oils being 20/50 since Harley uses that grade.
Using GL5 gear oil is not even close to GL1 which is what motoroil is. GL5 gear lube can be corrosive and it can also affect oil seals. I don't care what the maker of the bike is, why would someone choose a totally different fluid then what is recommended. Maybe that's why Harley got a reputation for oils leaks, people putting in gear lube.
Tires? Your not serious. But to answer your question, I will use the tire size stated for the bike, just like I will use the viscosity oil recommended for the engine.
HD 360 is not a C rated oil. The old HD oil leaks were from the engine not the transmission. GL5 is a 20-50 oil and some are corrosive to yellow metals. Big Twins do not have yellow metals.
Correct HD 360 does not list any API rating, so HD says if you don't use their oil use a API C rated.
Correct again, GL5 is a gear oil, yet Harley and just about every motorcycle maker uses GL1 motor oil in their transmissions, yellow metals or not should tell people something.
Will it make a difference? Most likely not, but one might want to question why do it,
