Wondering if someone has the correct answer on this one. I have search overload with conflicting answers. Here goes, just got done with my 63 unit chopper build. What the issue is the small amount of oil from the crankcase vent line. I have a custom oil tank feed, return and top hat vent. Is it safe to install a triumph crankcase h pipe and plumb it back to the top hat vent on the tank. Just want some feedback so Iam not over pressurizing my tank. I know this was a factory setup with the h pipe,but I believe a factory tank had two vents. Thanks for your time gents.
