OK, I went on a long ride and was returning from Monterey to the valley, a distance of around 150 miles this past weekend.
Bike ran perfectly
and I decided (like we all have at one time) to test its limit or top speed after interchanging from one highway to another with little traffic.
Funny, had never really done that before.
Well I buried the speedo at 120 mph pretty easily and quickly with it still pulling really hard.
A good thing yes!
Anyways continued at a really brisk pace because it began to rain on me, and my velocity stack does not appreciate precipitation very well.
Iv'e been dealing with a little more blow by than usual but I just wipe her up when there's the need (even while riding). Blow by comes harder
of course with higher RPM's.
As you may recall I have the Wimmer external breathers.
Cruisin along at a good clip with more traffic ahead I downshifted to 4th to get a charge to pass a long line of cars glued to the fast lane. When I hit 5th during a speed shift, it wasn't there,
instead a fake neutral and revvvvved her to its limit (of course only for a split second). Big bellow of blue smoke from the exhaust at this time. Off the throttle and put her in 5th and continued on....
For a moment anyways, until I glanced down to the carb side and holy shit
what do I see, what looked like a cup or more of motor oil sprawled on the side of the tank, upper rear head/rocker area, carb, my right upper inner leg and my inner arm sleeve.
Pressure was still up there around 20-22 lbs. although dropped a few pounds but stayed constant. A real freakin mess for sure but I was only about 15 miles from home.
Continued into town and stopped by my indy although it was now past closing time. No one there. Drove home and pressure stayed the same.
Got home and litterally poured fairly hot water with Simple Green around the affected area after the motor cooled a little.
Cleaned up the area pretty good and no appeareant leaks.
Next day nothing and cleaned her up even better. Started the bike warmed it and went for a short ride, nothing again except oil level was down around a half quart. It was down slightly too when I left for the coast.
Some background info...
When I first got to my brothers place in Santa Cruz I wiped up the usual blow by and then I got this grand (or stupid) idea
I don't know? to assist the small filter elements inside the breathers to better collect the oil. What I did was cut some of that blue absorbant shop cloth/paper and wrap it around the filter elements. I first tested the paper to make sure you could breath through it. Yes I could and I only circled the round filter once with the paper.
Of course my thinking
was that it would assist in soaking up some blow by; by eliminating it from escaping through the slots on the breathers. It seemed to work until the incident.
I'm going to head off to the indy shortly and have them check it out but I forgot to mention that when I cleaned up the area, I removed the paper that was still intact yet saturated as you can imagine. what I did see however was some orange powder coat material peeled away from the inner slots or vents of the breather. Nothing externally but evidently from the inner sides of the slots or breather vents.
With that being said, I can assure you that the vents or slots were not plugged, blocked or restricted by over spray of powder coat material. The coating however in the vents of the breather were not spot-on, yet did not concern me because you really did not see into that area.
I do wonder though if the blue cloth paper material, once saturated in oil may have compromised or severally restricted the intent of the breathers????
Of course with the slight blistering or peeling of the orange powder coat, I wonder if a bunch of oil puddled in the breather reservoir due to its restriction causing the oil to get quite Hot (seems unlikely though) and then finally having to erupt all at once and ending up all over me.???
For a clearer illustration I'm enclosing this pic.
What say you; experts out there?
