Hey folks, I searched a bit but didn't find anything on the newer dynas, assuming it's a different thread size. I bought m18x1.5 but they are way too big. Anyone know the size of the o2 sensor threading so I can buy plugs for V&H short shots?

Thanks much.

 

I'll see if I caN find the package mine came in to double check, but I'm almost positive it is 15. I put them in the straightshots that I put on my 13 sb.

 

Im at the store as i speak, it looks like its m12x1.25.

 

Hmm. Sorry about that. I don't recall them being that small, but then again the straightshots were not supposed to be compatible with a 13 because of the difference in o2 sensor size. The last year they made straightshots for a sb was 2011.

 

The 13s have 12mm O2 sensors. 11 and back have the 18mm...

 

yup, what he said.

 

Thanks folks, got it all lined out.

I got it finished up today .. just another question, that gasket that comes on those drain plugs, I assume yall removed those? For some reason I left mine on and it was smoking like crazy. I'm just going to assume that's what was causing the smoke but I'll double check it in the morning.

 

Am I reading this right that you removed the seals on your drain plugs? Probably a good idea to stick with the gaskets and seals that come with the bike.

 

how did you fix the smoke?
