Roadstar exhaust vs oil leak
I resently purchased a 2009 roadstar. I had a 2000 roadstar. I had a cobra exhaust and a K&N air intake on the 2000 road star. Because of the open air intake and exhaust I leaked oil out of the breather tube in the air intake. I am told by my local dealer that if I modify my exhaust and air intake in any way on my new bike it will leak oil again.
Is there any truth to this? I was told that due to the modified system on my last roadstar that access oil wasn't being burned up therefore it leaked out of the breather tube in my air intake.
Can I prevent this from happening with my new bike?.
