    I just wish to ad that in the 70's GTX was different, and from memory they did something to fix it as the word had got around about the problem with wet clutches. I think today some people still call it GTX 2. The damage had been done as many switch, and continued to use Valvoline XLD in our Honda 4's and so on.

    Sounds like a lot of us are in agreement.

    One note I'd like to drive home on using synthetics versus whatever,...

    Imagine the end of a steel alloy shaft and the surrounding softer bearing material...
    In an ideal world, the metal surfaces do not physically mate. At operational temperature, the motor oil provides a pseudo solidus material that prevents metal to metal contact.
    Engine oil, dependent of each unique type of engine, will provide an ideal viscosity to maintain an ideal separation between metal surfaces. Synthetic oil does not necessarily push out oil changes. But it provides robust viscosity at high temperatures where other petroleum products might fail. Maybe, because of the lack of "break-down" in synthetics the change interval is longer. But I'd conclude that defeats the purpose in a high performance engine. I'd choose to change as frequently as possible and use excellent oil.

    I know for a fact that using synth oil has prevented engine seize on VW air coolers. Having said that,... those engines were abnormally stressed and had no other means of cooling but poorly forced ambient air.
    The KTM has plenty of airflow when necessary, + fluid cooled.:wink:

    I use only AMSOIL in everything I have - with great results.
    I get it from Sliklube. He is a motorcycle guy and seems very knowlegable about his products. I listened to him at the BMW rally in Oregon. As I understand it he goes to the BMW rallies a lot.

    Rotella 15w40.

    I tried a few different brands (Castrol SynTec, Motorex, Mobil 1) and found Rotella works best on my bike.

    If I lived closer to Frank, I'd steal his used oil :lol3

    Where? Must've missed it with all the TOR threads.


    That would never happen with a KTM 950/990... :hide

    I thought I'd pass it along incase anyone is interested.

    I was listening to the podcast of Adam Carolla's weekly "Carcast" show. Last week his featured guest was
    Lake Speed, Jr.

    Speed, the son of former a NSACAR driver, is a certified lubrication specialist and oil monitoring analyst. He is also the general manager and head of technical support at Joe Gibbs Driven Racing Oil.

    It was a very interesting show with lots of good lubrication info. I think he puts to rest some of the typical views that some of us had about motor oil. Enjoy!

    Check out Carolla's other shows. His main podcast is great too.

    engine oil is over rated. I just dump a few bananas into it and the emulsion more than takes care of lubrication. exhaust smells nice too.

    So, after reading through all the posts here. I am still up in the air, kind of. I have a 2010 990 and have used the motorex since I bought it new. I did however run it to 6500 miles on one oil change :eek1, little to no offroading during that time. I am about to head south for a lengthy trip. While in Latin America I do not want to have to take a trailer with oil for changes. I rode a KLR for a short time and the dealership pointed out that you don't want "vehicle" oil in the case as the sheering affects of transmission literally cuts the molecules and does not provide the lubricating properties that is required for a motorcycle engine/transmission. For those who have traveled to the far flung parts of the world, Latin America, Africa, etc.... Is it safe to assume synthetic motorcycle oil will be available pretty much wherever I ride? Sorry for the seemingly naive question, but don't really want my bike to blow on me. I have traveled throughout Latin America extensively and have ridden (rental bikes, which required nothing from me aside from money for rental) nearly every time I travel. But I have not had to deal with those kind of things in the past. So it's new territory for me. Thank you for dealing with my naivety and questions. Oh another one: are the reusable oil filters as good as a paper ones? and what kind of cleaning do they require at oil change time? Thanks again!!!

    Use a oil that meets the viscosity and JASO MA requirements and stop worrying about it. Every oil question on the interwebs will get you 10 different answers on which oil to use. As for what is available in South America, I can't help you there. I'm sure you can google for whatever stores are down there and the type of oil they stock.

    As for the filter, they work the same, but the advantage to paper on our bikes is as a warning of a water pump failure.

    I would take the stainless oil filter. It can be cleaned with gas. As for oil on the road in Latin Am, I would probably use a diesel oil as it has closer to the same properties as motorcycle oil. Some larger cities, such as Guatemala City have KTM dealers where oil might be had. Also as a side note, if you havnt renewed your water pump shaft and all, do it before you go, or take a spare. Just my 2 cents

    Not too hard to find moto specific oil in Latin America, there are plenty of moto shops everywhere.

    At times I was able to find full synthetic Motul, or Elf full synth, other times only semi synthetic, and at other times just straight non-synth. If I ran non-synth, I changed it out at 2000 or so miles. Dont get too picky about your oil. If its something sub standard like non-synth, just change it out when you can. When I did a water pump change in a campground in the Atacama I could find no moto specific oil and the only oil I could find was Mobil 1, which worked plenty well as it has no friction modifiers that will mess up your clutch friction plates.

    Other times you have to look around for half a day, or wait until you hit the next city, but not a big deal.

    As far as paper or stainless oil filter, I used paper because I like to see the waves in it if the water pump is starting to go. I kept a couple stuffed in the dash compartment along with a water pump kit, and used and replaced as necessary, just plan ahead and stockpile when you can. Not hard to do at all as there is at least one KTM dealer in every country with the exception of French Guiana, Suriname, and Guyana. There may be a couple in CA that dont have KTM shops, Honduras, Nicaragua, Costa Rica, Panama, IIRC, but there are KTM shops in Guatemala City and San Salvador.

    I also used the paper air filter, but with a UNI prefilter. I cleaned the UNI regularly with soap in the sink and oiled with a touch of spare engine oil and that kept the paper air filter clean enough for at least 15,000 miles.

    I normally did oil changes in a parking lot, or hostal courtyard, but at times some shop owners were gracious enough to let me use some shop space which is very nice to have to do your valve check, water pump replacement, etc.

    In total I did about 12 oil changes, 3 water pump changes, a couple valve checks, 2 fork services, 1 shock service, 4 paper air filters, and cleaned my UNI prefilter every couple of weeks. Never did have an issue finding what I needed, but you can plan it out, and sometimes you have to look around a bit to find what you need but its not a problem if youre flexible.

    I would highly recommend that you keep up with regular water pump change intervals as it can be a pain in the ass to get oil and coolant when one fails and your far from anything.

    As good as motorex might be i got sick of paying near 20 bucks for a liter of oil so i got some elf 4xt tech for half that price and I'm almost certain motorex isn't twice as good

    Thank you very much for the advice I greatly appreciate it. Another question though, was the dealership who told me about the molecules in vehicle oil sheering from the transmission blowing air up my tail feathers to make a sale? Sounds like I'm on the right track as far as planning ahead is concerned. Traveling as much as I have done, being dropped off the side of the road somewhere in the middle of nowhere to catch another ride to nowhere, bus breakdowns and helping get it back rolling again, dealing with protests that shut towns and roads down, all my travels have taught me that flexibility is one of the biggest assets you could have while traveling. 3 1/2 weeks and counting: I'm so damn excited to get rolling on this trip. Thanks for your input!!!

    Cheers,

    Molecules isn't the right word, and a bit silly, but he was right about not using car oil. Car oil has additives in it that are no good for our wet clutches. Stick with a motorcycle oil, or some diesel truck oils (Rotella T). As I said above, viscosity and JASO ratings.

    Rotella,not many out there that runs their bike harder than me. I ride my 950 like I'm mad at it. It has a lot less noise too.

    Ive been running Rotella T6 (5-40) here in the so cal summer/winter as well....ticks on hot startup sometimes but it did it just the same with the 1050.

    Clean scotts filter, very minimal wear material on mag plug.

    $20 / gal.
