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
I placed a Krankvent in the line about the height of the carb and petcock, then ran the line over the frame under the seat, back down and to the rear. I removed the can entirely and plugged the other vent on the case where the return line from the can had gone with a rubber cap. No more blowing oil. Less vibration too.
I used the Universal 3/8" Barb Kit. I ran the hose straight up from the oil tank nipple (large hose going to oil can) and hung it from the frame with a wide Tie Strap. The Krankvent is just below the tank, pointing straight up. The hose curves and runs back along the frame to where the old oil can was, then down behind the left tool box and back along the frame to the rear of the fender. No oil has ever come out. I feel a little puff puff at idle there. I can't hear the Krankvent ticking or tapping at all.The timing case nipple (smaller of the two hoses going to the can) is capped off with a vacuum cap and small clamp right at the timing case. Oil can is sitting on a shelf in the garage.The vent line must run straight up from the oil tank nipple to keep oil from running out the line. If it doesn't go as straight and high as possible under the frame there is no point in bothering to do this at all.I'm out of town or I'd post a pic for you. I will upload a pic tomorrow night.
Which of the Krankvents did you use? It sounds like you are using an inline vent device. Is there a purpose in running the vent up high and back down? Do you mean the rear of the motor or at the end of the rear fender? And you capped the primary case vent? What about the timing case? I have read this entire thread and I'm still concerned about what to do with the minor lines.
