I had a SE cone shaped air breather put on my 09 serg and the bolt`s were wrong so they had to be changed out. My ? is ,my buddy had one installed on his 09 street glide, do the bolts need to be changed on his as well . Or is this just on the serg?    Thank`s  JP

There are a few different types of breather bolts. If you don't have the right ones in, you'll create huge negative pressure on the motor because the crankcase can't breath. I know because this happened to me when I installed the touring heavy breather on my 08 SERK. After a short test drive the engine quit and smoke was pouring out of the breather and exhaust for a few seconds. I opened the oil cover, and negative pressure rushed in like the sound of a shaken pop can. I had it towed to the dealer and they determined the incorrect breather bolts were not installed. I was confused because the touring heavy breather kit said to use the same bolts. I think my problem was that I had the dealer put on a Stage 1 kit first, and apparantly the breather bolts were different for that kit. They put my stock breather bolts back on and everything worked well after that.

I have the stock bolts on mine now, no problem (at this time) but the dealer ordered me the right one`s that were talked about on the site. I gave him the part # i got off the site. My buddy had one put on his 09 serg and had a problem, why am i not having a problem? Same stock bolt`s used on both.

If you have the directions to the heavy breather a/c, they say to use the "stock" breather bolts.   So your friend with the street glide is fine.  The new SERG came with a high flow a/c already with non stock breather bolts.  That was the source of the problem.  If you search "SERG breather bolts" you'll see the prior discussions.
