Just because someone has money doesn't mean they has smartz. The "more money than brains" club is hugely membered. So is the "I don't need to be smart, because I have money" club.... What I find MOST amusing, is how radically ill-informed people owning high-dollar high-performance machines are about oil choice....
I think the most common denominator in this thread is just the viscosity. I believe I've seen 15w/40 or 15w/50 mentioned the most often in this thread. Beyond that, it appears that one should just buy any well known name brand at the best price, as long as it it 15w/40 or 15w/50.
Since I live in the same region of the South Western U.S.A as Member *RockAZ I think I'll go with his preference. Along with that, use a K&N KN-153 filter, as that particular filter was most selected in another thread that was a ~poll~ on filters used by quite a long shot.
Change often, be observant, and even take notes on what has been observed ...
These were happening a lot to Triumph owners (maybe others???). It looks like they were having problems with the nut that was welded to the top of the filter. Here is a picture...the guy says he hand tightened it like he always does, so it wasn't from him using the nut to tighten it.Interesting, every couple of years I've heard things like this on the K&N, in my experience it is because the installer used the "nut" built into the filter to over-tighten it which can tear the rubber seal off from the filter. That "nut" is only supposed to be used to remove the filter, not tighten it on. K&N 153 does come with safety wire holes ready to use, I can't imagine a properly installed and wired one would come off or leak. I've just read this morning about a couple incidents leading to the track bans where it was mostly the K&N 204 model which fits many bikes that had the weld come off the nut that had been tightened by it. Tech insisting on only the manufacturer's filter is just a legal cop-out, in my opinion - no guarantee that they will do any better but the manufacturer could be held liable.
I took the pic from the thread on the triumphrat forum. i use KN-153 on my SC's and I still use a KN-204 on my 05 thruxton. I was a little concerned when i first heard about it but i read something where they found out that they had a problem in the manufacturing and fixed it. I don't remember the details. With three bikes I have been through at least a couple dozen K&N filters over the past few years and never had a problem with any of them.Impressive pic - that "nut" is very different from the KN-153 style, and this pic shows a complete failure! What a mess,...
And yes - that PN is 204 - the one identified on several forums as having severe quality control/installer failures.
No part number specified? No "reason" specified? My bet is pretty much what other members have spoken up about, it's not that the K&N is a "bad" filter, it's that you have too many Junior Racer Boys bust out their Junior Mechanic's Tool Box and misuse the nut on the filter. Most rules are there to protect squids from themselves, and to protect others from squids. Same goes for most traffic laws.Just a heads up...I was checking a well known track day organization's calendar the other day, and they had a big warning posted.
No K+N oil filters would be approved at tech, as they have had too many of them fail on track.
I saw on another forum that the Thailand factory that makes the K+N (and also the HiFloFiltro) buggered the threads up...so I'm guessing the filter blew off and oiled the track.No part number specified? No "reason" specified? /---------/
So what precisely are we looking at here? Since there are two completely different angles, and totally different looking valves, it could appear to someone that it's a picture if an exhaust valve ... and an intake valve. Obviously one is going to be cleaner than the other. That having been said, I don't understand what point Member *Buhgaboo is attempting to make.It's still a work in progress....switched from mobil1 to shell...I don't think I'm switching back
