I own a 2015 RGS, stage 1 tune and SE Mufflers, I bought a Heavy Breather kit from HD in Tamworth on a trip through the area. When I got home I fitted the kit myself, all was good until I took her for a short ride 100klms, sitting at a set of lights I notice smoke wafting past me, it was coming from my exhaust, AND LOTS OF IT, any way pulled over turned her off, checked oil and it was very very low, topped her up and rode home and she was blowing a huge amount of smoke, checked again and it was low. I have heard about oil blow by with this breather, so I put the original cleaner back on and have had no more issues. I contacted HD in Sydney and they told me I had not fitted it correctly. It appeared to be quite an easy replacement so not sure what I have done wrong. Has anyone else had this problem and if so how do I fix it.

Thank you for reading.

Check the bolts that came on the fitting kit and see if one is hollow with a side drilling.

Good luck.

From memory it is the top rear bolt that has the breather port. Should be easy tp work out wish bplt holes are blind ones.

If you have a workshop manual to reference that would help.
