Oil filter and lines...

  This street fighter is finally coming together. Since this bike is running without a battery, I decided to tuck the oil filter behind the motor. Its funny that the oil filter is one of those elements that can make people love or hate my bikes. I think leaving them bright orange is a slightly industrial, utilitarian touch that reminds people that the bike is more than really expensive sculpture, and should be ridden.
That, and the fact that changing them is as simple as getting a different colored filter, getting an oil filter cover, or painting it, which is the option I'm going with this time. The point of tucking it behind the engine is to make it a bit less obtrusive, and play with the shape of the oil lines. 

    Lesson learned from copper prices going up: copper tubing has more grades than it used to. On the right is the cheaper stuff which should not be used for running any sort of line with a bend in it. I picked up a batch by accident, and it was thin, brittle, flattening on bends, and all around junk. On the other hand, it was perfectly serviceable for mocking up a few different options, and cheaper then screwing up on the much better stuff on the left. Good copper tubing should be heavy, soft, and hold its shape well when bending. Apparently it also costs near twice what it used to.

 I use flare fittings. Compression fittings are generally meant for stationary, one time use; and when it comes to a solid oil line, using something that is more reliable when under stress and vibration, and rated for fuel systems is a a good idea. 

Standard mount on the left; current oil lines on the right. A bit cleaner and perhaps graceful?


  1. Ya, but George you painted your bike pink.

  2. Hey this looks epic! I've got a 69' daytona 500 and am looking to set up my own custom oil filter/lines but I've not been able to find much knowledge on the positives and negatives of running a custom filter minus the traditional oil tank, as people say you need at least 1.5-2 quarts of oil standard. I'd love to hear your advice if you've got any!
