Mine is shifting hard especially after the 1000 mile check up. Took it back to the dealer they called HD & they said it was because I am using they syn. Next time to switch to a higher synthetic gear oil in your 6-speed tranny? Next week it goes back for the 2500 oil change & they are going to change the tranny fluid then. Makes no seance to do what HD says & upgrade to they synthetic then have problems with it? I am going to see id they will put it in writting (ya right)

I know Shockproof Heavy has a lot of fans around here and I'll probably get flamed for saying this, but it just doesn't make any sense to me to use a gear lubricant with solid particles deliberately added, microscopic or otherwise. It reminds me of the Slick50 gimmick with the Teflon. I'm sure it's safe; everyone who uses it raves about the results. For me, I'll stick to the liquid-only gear oils.

I run Amsoil synthetic ATF in my primary and it doesn't make a noise going into gear. Redline shock proof in tranny. IDS has been in the box for a year and will probably stay there. Maybe I'm lucky but my bike is smooth running and shifting with synthetic. As a side note my oil temp dropped 15 degrees with Amsoil synthetic in engine.

I think he's talking about the famous Amsoil "White Paper" that's being touted as an independent test when it clearly is not. Amsoil is a fine oil, not objectively better than anything else overall, but some have elevated it to a religious icon. That test I presume he's referring to was on motor oils, not gear oil, and was financed, sanctioned, and defined by Amsoil. I've challenged Gary to give reference to his claims but have yet to hear from him.

Anyone who wants to view truly independent tests, there have been three that I'm aware of conducted by motorcycle magazines: American Iron, Motorcycle Consumer News, and Quick Throttle.

What solids are you referring to? Moly? If so, it isn't really a solid, per se, and isn't even large enough consistency to be captured by oil filters. Further, moly is used in almost every major brand of synthetic motor oil, Amsoil and Syn3 being the only exceptions I'm aware of. Anyway, solid lubricants are appropriate for a tranny because there is no filtration.
Like I said, many are happy, it's just not for me.
