Roadies:

I know that a lot of you are venting your crankcases to places other than the air filter, in order to eliminate the possibility of oil blow-by fouling up your carburetors or air kits.

Some of the options that I have read about are:

- a motorcycle-specific crankcase vent
- PCV valve
- external air filter
- open hose/tubing run to the ground

What is the preferred method for venting the crankcase?

How much does it cost, where do I get the parts (part #s would help, too), and how do I complete the installation?

Thanks for your help.

When I switched out the stock air filter for a K&N. I re-routed the the crankcase hose to a chromed filter. But I learned later after talking to a tech that it's best to mount the filter high and away from the weather (rain & wind). High - so that if oil does blow, it'll drain back to the motor; Weather - so that rain & wind don't have a chance to blow thru the filter and into the motor (just being precautionary, there are rare occasions of it happening). Under the right case cover. I ran the hose up under the tankand followed thr frame down thruogh the battery area. You'll have to use a coupler to extend to get behind the case cover or just buy a long section of hose. You can buy a crankcase filter at the auto store that's not as spiffy. If I would have known then what I know now, I wouldn't have went chrome. My pic size is too large to post, but have several if interested. Just let me know where to send them.

He's a popular option http://www.hellrisercustoms.com/selector.php?group=1&amp;category=Intake&amp;title=Air%20Cleaners%20for%20RoadStar

I have mine open and draining to the ground. Articwolf has an interesting comment re oil draining back but I've only seen water drip from mine on my interlocking driveway .

Doc

I hate when the bike has a drip (and not meaning me either ) I know alot of folks who have their hose just open and draining. Just don't like the idea of leaving evidence of where I've been. Some people have this fetish about their driveways and being purtty looking.

You have to think about where you live.Here hot , dry , dusty.
I`m running crank vent and a filter.I don`t want 'any' road crap
being sucked back into the engine.

I agree with you there. I'm always riding anytime &amp; anywhere possible. And where I work is by the river and next to a high-level bridge plus the tractor trailers kick up the dust coming in to the plant. So I get high and low. Just dust er` off when I get home is all.
Shoot time to get ready for the 'Pittsburgh Bike Expo'. Talk to yinz all later.
Stay safe.

Good info. Does it matter which crankcase vent filter you buy? Is there a popular one that folks use?

Also, do you know what diameter hose I owuld use?

Thanks. You've been a big help.

Ray

Yep.

After I get my MaxAir airkit installed, draining the tube to the ground may be my 'quick-fix' until I can get hose and a PCV filter installed.

Thanks.

I'm with you, Articwolf.

I don't think I want to be leaking in my driveway. Plus, I like the concept of keeping oil in the engine and dust and water away from the engine!

Thanks.

Interesting...

What does your set-up look like?
