You have to look at your engine, and divide it into one of two categories. Now basically, all engines have to do what we call, breathe. As the pistons travel up and down inside the cylinders, they’re displacing air. The air has to go somewhere, and it’s going to carry an oil mist with it. You have crankcase breathers, and you have head breathers. In the early 90’s, Harley went to a head breathing design, where the engine actually had two bolts, one here, one here, where the heads, the breathing, actually came out through there, and they had it channeled into the backplate of the air filter, right here. If you get misting, oil misting, or carryover from this area, it’s usually because the bolts themselves, or the tubes, or the channeling system, if you’ve gone to an aftermarket air cleaner, is not fitted correctly, or is not attached correctly, or the tubes themselves had deteriorated, and cracked, and allowed the oil to escape.
Crankcase breathers more commonly, initially, were vented right out to the air. EPA came down, put their foot down, and said, We need to run these things to filters, or run them back to catch cans, or so on and so forth, so if you get a crankcase breather that’s got too much oil carryover, chances are it’s coming out somewhere on the bottom of the bike, and you could put a filter or a catch can on that, to keep that from misting the back tire, which could provide a dangerous scenario, or a lot of other places, will figure out a way you can route them back into the air cleaner, from another point, as we did on this sportster here. This was its original breathing line here, and we routed it up to the back of the air plate. What this does, is it takes the mist, and recirculates it back into the motor, so if you’re having any issues with oil carryover, with your Harley Davidson motorcycle.
Using Slick 50 In Harley Davidson Twin Cam Engines
Slick Fifty is basically a brand of synthetic motorcycle oil, as is Ams Oil, Harley Davidson Syn Three and V-Twin synthetic by Bel-Ray. As far as choosing a synthetic for your motorcycle it’s just as much a decision as choosing where you would like to eat fast food. McDonalds, Burger King or Wendy’s. A lot of times it’s preferential, a lot of times depending on the bike, if it’s a high end performance bike like say it’s a Suzuki Hayabusa, you may want to go with something that the company actually recommends, if they have their own synthetic.
Again, if you’ve seen infomercials, testimonials, and it looks good to you, it’s not usually going to hurt you to try it once. If you’re switching from a standard lubricant, either a 20w50 or a fifty weight oil and you’re going to a synthetic, you don’t want to do it on an engine that has a lot of miles on it. You can actually run into problems. But again, Slick Fifty is just another brand of a synthetic lubricant, it’s been around the longest, and therefore it has a fairly good history. But there are a lot of other contenders out there. Any further questions I would recommend consulting the web and doing some research and finding other folks that have used it or used the other products and get their take on
