At royal purples website they have a "Find a dealer" link, I found three places in my small town that sold it. Napa Auto Parts, Jerrys Auto Supply, and AutoZone. I paid 8 clams a quart, good luck in your search!

I have been running Lucus 20w50 in both holes and i really like it. And it is LUCUS great stuff. Just another Idea.

I haven't heard much about Lucus oil, but a lot of the additives they sell that are supposed to be awesome (like the one with the display with the gears and the oil that reachs to the top gear and looks so wonderful) are not. They cause cavitation like it's going out of style, which means terrible protection.

I have always ran Lucas in all my bikes and cars and have Never had a problem. Took my car into the shop for a leaking timing gear cover and he ask when the timing gear had been changed. When I told him that it had never been changed he was shocked. said with 100,000 miles I should be replacing the tensioners and the chain. There was hardly any wear on the tensioners. I have been sold every since. Just my observation. Lucas fuel treatment is great to.

so amsoil and rp don't have any additives that cause it to be a risk in the primary... what about Mobil 1?  does it have the feared anti-slip or anti-wear agents?
Posted:  12 Sep 2008 14:57 [?]  
If it's designed as an engine oil then yes it has anti-wear agents. They may make something that doesn't have that in it. Check the website or give them a call and they will give you the skinny. Anti-slip comes in gear oils designed for differentials with limited slip in them.

I posted this on another thread but am just thinking it also kinda applies to this thread:

Well, I just opened the transmission up to check it out and although the level looks good, I think the fluid itself is all jacked up.  I've never looked in a transmission before, but the most "liquid" of the substance inside was a true gray color and then there was this greyish yellowish substance more the consitency of cream that was caked on to the inside of the clutch inspection cover.

it didnt smell burned but it sure as hell looked strange and even a little of the creamy part looked a little bubbly so i guess burned.. damn. 

i havent checked the clutch adjustment cause it doesn't "slip" or "drag"..

please help, that just scared me...  I will definetly be draining it and will replace it with some royal purple maxcycle or whatever, but like, since its all sludgy do i need to do something else, like should i wipe that shit off the cover???

prob water in the primary from the clutch adjuster boot. posted in your other thread too.. .
Posted:  13 Sep 2008 14:54 [?]  
Typeones right. Some water got in there and its contaminating your oil. Nothing is probably ruined, but definately should be changed. Get some brake cleaner from the auto parts store and the gaskets to reseal it and drain it, wipe it out, then brake clean it to get out the last of the gunk. Then fill her on up.

will do.  ist that the only place water could/should be getting in from?  the boot?
Posted:  22 Sep 2008 14:05 [?]  
Good discussion here, following with interest. The boot on my XB9R clutch cable was very loose at the top and tight at the bottom, which meant any water just sat there seeping into the cable adjuster and hence down to the gearbox. Hopefully it's now cured with a few wraps of self-amalgamating tape round the top.

On a related note, I asked my HD Dealer for 'Oil for a Buell XB9R transmission/clutch' and he sold me Formula+ lubricant (Pt 99851-05). Now I see the handbook says use Sports-Trans Fluid (Pt 98854-06). Should I take it back and change it or doesn't it matter?

Ralph2, either will be fine.

Thanks Bordsnbikes! Gotta get me that paddock stand and change the oil soonest.
Posted:  23 Sep 2008 19:55 [?]  
what i'm worried about is even though i have the boot sealed now that there is still water in the cable.. not sure why but relubing it just seems like a pain
Posted:  23 Sep 2008 20:08 [?]  
buy a new one, they're better quality now anyway, even different than my '05 cable.
Posted:  24 Sep 2008 04:40 [?]  
The amount of water that could be sitting in that cable is nominal. I wouldn't worry about that.

More Info. I kinda shy away from Amsoil, It destroyed the transmission in my Jeep after a rep told me it was the best thing for it. 
I like the Mobil 1 stuff. Its also what S&S motors uses in their V's.


Mobil 1 V-Twin 20W-50    Mobil 1 V-Twin 20W-50
Formulated specifically for four-cycle V-twin engines. Key benefits of Mobil 1® V-Twin 20W-50:

    * Outstanding resistance to thermal breakdown.
    * Optimized for hot-running, air-cooled engines.
    * Enhanced lubrication for peak horsepower.
    * Protects engines against harmful dirt deposits.
    * Excellent transmission performance.

Mobil 1 V-Twin 20W-50
    Mobil 1 V-Twin 20W-50 is recommended for four-cycle motorcycles that specify the use of a 20W-50 engine oil. It provides excellent performance in motorcycle engines that are designed with a common engine/transmission lubrication system or where the engine lubrication system is separate from the transmission system. In the case of the latter, follow the manufacturer's recommendation for the type of fluid to be used in the transmission. Mobil 1 V-Twin 20W-50 engine oil is also designed to provide the proper frictional characteristics necessary for wet-clutch engine/transmission systems. Mobil 1 V-Twin 20W-50 exceeds the requirements of API Service Categories SH, SG/CF, CD and has been fully tested, both on laboratory dynamometers and in the field, to provide optimum horsepower and acceleration.

Fully synthetic Mobil 1 motorcycle oils are specifically engineered for use in motorcycles. The formulations are based on the proven technology used in other Mobil 1 automotive products, yet they are optimized for the unique requirements of a motorcycle engine and/or transmission. You can use them with confidence, knowing they will protect your bike in extreme situations where conventional motor oils simply can not stand up, including extended high-speed operation and prolonged idling in summertime traffic.

For more information, see the Mobil 1 Motorcycle Product Data Sheet and Material Safety Data Sheet.

Gator Buell i also use mobil 1 V-twin in my new buell but don't you think your transmission going out in your jeep could have just been a defect,ect. or just one of those things? Its hard to go wrong with today's oils they came so far in the last 10+ years. I've put 100,000 miles between 3 bikes using 20/50 castrol oil GTX with no oil problems and there's better oil out there. Sometimes i think people make to big a deal with today's modern oils.

It was not until a few months later that I found out why the Amsoil destroyed my tranny. It was the High pressure additives and phosphorus in the oil deteriorated the yellow metal (brass) syncro gears in a matter of 8 months. It is a GL5 hypoid gear compliant oil and not to be used in older Asiain AX-5/15 Jeep transmissions. The rep should have known that it was a GL5 and not backwards compatible to GL3 oils.  When I asked the rep he said that oil was the best available for my year, make and model Tranny.  Live and Learn, at least now I know how to rebuild a 5 speed transmission....

Si is the amsoil ok? I've run it for about 3500 miles now and I like it.

Yea you will not have a problem in the Buell. Im just a little pissed at the company is all and I like Mobil 1 stuff so thats the direction I go.

Sorry to hear that gatorbuell, i'am pretty sure that GL5 hypoid gear oil 75-90wt. used in a buell or sportster will do the same deal in the primary. It eats away the yellow metal (copper)on the stator. I can see how that could happen with amsoil's anybody can be a instance distributor/dealer plan.
