Oils

Recommended Posts

I was curious as to this too. I changed my oil after a 2.5 hour break in, and new filters, with Yamalube 20w40 oil. I will run this until my Scotts Filters come in (probably only 4 hours or so on this Yamalube oil) then I will change it again.

My dealer called into KTM directly while i was standing there, and the guy that works with some of the factory riders actually recommended Silkoline RACELUBE 20w50 or 10w40 (colder temps.) The Racelube is a synthetic fortified oil. They also (KTM), recommended the Stainless Scotts filter.

Personally, to me it's a no brainer on the filter. My '01 520 will get good treatment, and it will get REALLY OLD changing filters at $30 a pop after 15 or so hours. THe Scotts filters are $70 each, (140 for the bike), but the higher filtration and cleanability makes the filters pay for themselves after 4 paper filter changes!!!!

E-mail me with questions. chriss@moldbase.com or DethWshBkr@aol.com <---(more checked)

I have being cheking the ss filters. I'm concerned about the filtration rate wich is 30 micron. Do you know what is for paper ones?

Interesting that KTM would recommend them. I have a contact in KTM USA service and he told me recently that the KTM factory is still evaluating the SS. Up until they approve them, he said they would void your warranty. He said he'd let me know when KTM ruled on that one but maybe I should send a follow up note.

The problem seems to be that repeated cleanings tend to open the screening and eventually they start to let larger and larger particles through.

I get a pair of paper filters for about $9 per pair from Mike Krueger at Cycle Zone KTM (toll free 866-843-7433). At that price and only changing them every 2-3 times I change oil, it seems cost effective and safer to me.

The micron filtration range for paper filters is supposedly 80-90 microns.

Hmm, well, the KTM guy that was spoken to mentioned the Scotts Filters.....guess he wouldn't even mention them if they voided the warranty. Right? ( I hope so anyway! )

Do not take anything for granted with warranty, particularly an aftermarket filter! Unless you have a letter from KTM to customers approving the use of the filters, or this ONE guy youspoke to is THE man that handles / approves warranty claims.

There are thousands of "KTM guys" out there who can innocently misrepresent the companies position through normal conversation

I agree with Max. I'm trying to get the official word on this, too.

As far as Micron ratings, I've been looking around about that, too. Paper filter manufacturers claim a much better number, in the 20 range for some, than the 80-90 that Scott's says paper is good for. Apparently, that number is hard to really nail down and may be somewhat meaningless because of that. The rating system somehow allows you to say you have a 5 micron fitler rate but the filter actully lets much larger particles through as it must also satisfy a certain flow rate.

If the filter did only allow 5 or 10 micron overall, for instance, it would starve the engine of oil.

Depends on how you clean them, from what I've read. Using compressed cleaners or air can open up the mesh. Using any kind of brush or the like can also do that. Seems the only safe method is to use a cleaning solution gently from the inside out and let them air dry.

If cleaned gently, the worry seems to be that the particles aren't getting washed out well enough and your flow rate suffers. A few guys said they'd just toss the SS filters every year and buy new given the above. That sounded like a good idea when paper filters were so expensive. But at the current $9 a pair, it would seem more cost effective to use paper if you're going to toss them yearly.

Again, that's just what I've picked up from the net. How do the filter manufacturers recommend cleaning them?

I use a solvent tank and clean the filters with the solvent coming out of spout. Very low pressure stream.

I would think that the engine oil is under much higher pressure and full of all manner of crud, ergo, causing those little screens to open up over time.

To put a furher twist on it, the long and short screens are stainless mesh...do they open up over time? And I've heard nothing from KTM about being worried about them. Perhaps they perform a slightly different job in the "grand filtering scheme . . ." but. . .

I suspect the bottom line in all of this is, "you pays your money and you takes your choice".

And on that note, I'm going riding this weekend and not worry one whit about my screen opening up. ;-)

Have a good weekend!

      Looking for something a little lighter and faster to supplement my xr650l and I think this bike might fit the bill. I'm hoping there are some owners here who can give me some insight into the typical experience with this bike. The question I'm most concerned about is how many hours these engines last before needing a rebuild with normal trail riding? Also, how do they handle in technical terrain? How about on the road? 
       
      The machine I'm looking at has about 75 hours and 1,500 miles on it, all stock other than a lectron carb, and comes with some dualsport lighting not installed. The current owner's asking price seems pretty high at $4500, but he seems to be a communicative, eager seller, which is practically unheard of in Upstate NY where the vast majority of dirtbikes on Craigslist are owned (or "owned") by rednecks trying to flip them. I'm willing to pay a little more than market value for this reason.
       
      Thanks for any input!

      Hi all,
      I got a set of the Axis passenger pegs to fit my 14' 500 exc. The bike does have the alloy sub-frame, but I'm curious if anyone has used this set up with success without destroying the sub-frame or their wife/gf? 
       
      Short trips like errands and rides out to the coast for hiking. 10-15 miles on the longer rides, and likely 0 miles on the highway, as she is not super stoked about riding. But our job kinda doesn't allow multiple vehicles. Yachties. Also shopping a sumo set up at the moment too. 
       
      Thanks folks!!

      Recently,I took a trip out to Colorado for some R&R on a family vacation. I brought my riding gear and had planned on renting a bike, but I was too late and at least what I looked at, there was no availability for my timeline. Bummer, since I'd not ridden the rockies in over 4 years, something pretty special when you live in flatlanderville (Florida)! 
      But, behind the scenes, a couple of TT'ers were at work! Through TT, we recently hired a fine, young gentleman to head up our advertising sales team,( @Freemotion ) and he pulled some strings with a local who had a well equipped  KTM 450XC-W that is his back-up machine. His new love is a 2019 KTM 300 TPI and it was gorgeous!
      So, a HUGE thanks to @Freemotion for greasing the skids in getting me a skoot and to @G 9.5 for generously lending out his bike to basically a stranger. The weather was great, so was the company, and the riding was epic as far as I'm concerned. I'm still a bit humbled by the generosity, so I wanted to share a story that I bet isn't as uncommon among the riding community as one might imagine.
      Dirt bike people rock! 🤘

      Hello TT peeps. I currently have an 11' Ktm 450 exc which i am converting to sumo. Still on the fence about getting cush drive rims or standard rims. Not too much info on what cush drive does for wheelies. I know its smoother on the tranny and chain but will it make much of a difference with slower wheelies/stunting? I had a DRZ with standard rims and slower wheelies were very choppy and almost impossible to control smoothly. Any advice/tips/help will be much appreciated. 
      Also.... will 5" rims be pushing it for chain rub? Should i just stick with 4.25"?

      Hi, I was wandering if anybody has recently bought or sold a 2014 or 2015 500 exc?  I'm trying to get an idea as to what they worth presently.  Thanks for any help.
