Changed the oil on my 2008 Fxstc yesterday and went for a ride today and after riding for a couple of hours I stopped and deceided to check the oil and it looked bubbly when I looked down the filler pipe, is this normal? I used redline oil 20w50.

 

My Sportster used to do that when I changed the oil. The bubbles went away and I never had a problem.

My '02 Heritage didn't 'bubble' when I changed the oil in it a couple of week ago.

I don't know if air somehow gets into the sytem causing the bubbling or not, but I used a scavenger system with my Heritage and it didn't bubble.

I have been changing and checking my own oil since I bought my bike. I use SYN-3 and I also notice what I would describe more as a foam after riding for a while. I never thought anything of it and I have never had any issues. My engine seems to run as good as the day I brought her home.

 

Both my Heritages do the bubbly thing.

 

That's that Champagne Oil!!

 

That's because Redline is the champaign of oils,if you used regular oil it would be foamy because it is the beer oil!

 

just be sure that it was not over filled

 

I have the same thing, and I also use RedLine. Its normal.

 

Bubbles here as well.
