Re: So I don´t understand

how this 2 Husa owners in Spain had the same problem, different year and every one of this bikes for what the owners said, 05´2200 km 73 hrs services like manual syntetc oil, original oil filters, the other 05´4000 km every 3 rides oil change and every 2 changes of oil a new filter, he said special treatment an exaggeration, and look at the result.
My question is there a way to prevent this failure off course riding the bike every weekend 5 hrs or more.
15 hours (3 rides times 5hrs = 15hours. Is that about right or do I have that wrong?) seems like a bit much on an oil change on a regular basis. I change my oil after every ride, just about. My rides being 60-100 miles and anywhere from 2.5 to 5 hours. Even with the synythetics I wouldn't go more than 10 hours on a reg basis. I also use a Sott's screen type oil filter that I clean about every three oil changes. I use Motul 5100 15W-50. This is a synthetic blend oil. Most of the time my oil comes out a darker amber than when it went in, not black. Take your used oil in the pan out into the sun light and see how much crap is floating around in it. Now adjust your change interval from 15 hours to 5 and see how much crap there is in the oil.
Just for the heck of it, take one of your used oil filters and cut it open laying the pleats out flat. You won't need a magnifying glass to see all the stuff in the filter, but, use one and see just how much stuff is in there. It is possible with those change intervals that your filter is becoming restricted and the bypass is opening and allowing the unfiltered oil to circulate through the pressurized system. This is even more common when starting the motor from cold and the oil is at it's highest viscosity.
It also has a lot to do with what kind of riding you do. If you're doing alot of high load high revving stuff like open area riding, or if you're racing you're going to put a lot more wear on the engine than if you are doing tight trails with moderate rev's.
Slipping the clutch a lot also puts a lot of wear on the oil (heat) and creates a lot of debris. While Synthetics have a high resistance to vaporization, and gauling, unless the proper type of filtration is employed the oil becomes contaminated with debris over time. Debris that perhaps the stock oil filter is not filtering out, or is and the oil is not flowing through the filter due to restriction and is flowing through the bypass.
You asked if there was anything you could do to prevent these failures. My suggestion would be to go to a more frequent oil change regimen. Oils like Motul are about half as expensive as the typical synthetic, and as such your cost will be the same as far as that part of the maintenance goes. Change the oil every 5 hours, change the filter every two rides, unless you go to a Scott's filter . You change the oil filter in your car everytime you change your oil right? The stock filters are cheap anyway. The Scott's filter at $75 is not cheap but will last you for the life of this bike, and the next as long as they keep the same size oil filter.
I have been using the Scott's filter for 6 years now, along with the Motul oil. The only one of my Husaberg's that had a bad big end bearing was the 94 & 1/2 501 when I bought it used. My other two bikes, the 01 501 which has 200 hours on the crank big end bearing, and the 04 550 which has 165 hours on it are still on the original big end bearings. The 01 had a lot of desert racing miles on it, along with trail miles, and the 04 has mostly trail miles on it, and about 30% racing miles.
