I'm back to the catch-can. Don't like the oil dripping out of the breather hose and on to the ground. I think I'm through with this modification attempt for now.
Cheers,
Bill
Me, too, Bill. I will NOT have a puddle under a bike. Lonnnnng ago I got sick of that being somebody's first comment.
I've followed this thread (& others) faithfully & gone through a lot of machinations over the past couple months. Cold weather has stretched the time out. Not super cold, but chilly enough to limit long rides (I'm like an old turtle in the cold).
I tried ALL the ways to deal with the crankcase breather:
First I ran the hose up high & then down by the centerstand with a duckbill. Result? Fine oil mist all over everything including the rear tire plus I can't stand the tiny puddle under the bike when I shut it down. I have an oil-tight '77 harley shovelhead & I am CERtainly NOT having an ''08 Enfield with 300 miles on it with a puddle of yellow oil foam that looks like a dog throwing up grass under it.
Second I ran clear Tygon tubing all the way along the fender braces with TyWraps & out at the rear tip of the rear fender. Result? Looks way too Rube Goldberg for me & will attract irritating comments from riders who don't even CHANGE their own oil.
Third I ReRan the OEM hose back down to rear of the tranny with a small plastic Listerine bottle catch can & duckbill on end of hose. Made tiny air holes in the top edge of the catch can. Result? Did not like the look of it & again it would just attract stupid comments.
About 2 AM one night (these kinds of things drive me nuts 'til I solve them) I suddenly had an "Of course, Dummy" moment. Your right side air cleaner box is EMPTY since you put the K&N on, Dummy. I went down later & first plugged off the timing case fitting. I don't think that hose is necessary (Please tell me if I'm wrong. Nobody did on my previously posted question).
Then I ran the CC breather hose up & over the carburetor & down & into the hole in the air cleaner box & put the duckbill on the end. It has a nice high loop & it ends up pointing down inside the box (perfect) because of the threaded bracket on the air filter hole. I then duct taped all the openings shut & rolled up a nice big piece of old thermal underwear to lay in the bottom of the box to keep oil (if there IS that much) from running out through the hinge.
I ran the bike for about 5 minutes in the driveway & got NO oil at all on the rag, but that proves nothing. I shut the box & went upstairs.
Today looks like it's going to be warm enough to maybe ride 6 or 7 miles before this old turtle freezes up.
Will report later.
PS: Since I talked here last about dialing in my carb (BS-29 CV) months ago & running out of throttle, I've raised the needle one more shim & it's running like a stripe-ed ass ape now (well, everything is relative ;>) Of course, I won't REALLY know until the weather warms up & I get more miles on. I'm still only at 330. I hope that's at least 400 by April 1st. It starts 2nd or 3rd kick all the time on these 30s & 40s degree days. One kick when hot.
