I bought a 2009 head pipe with shields and a crossover to put on my 2010 Street Glide. It has the standard 18mm bungs in the stock location. I want to add the 12mm bungs in the stock 2010 location to 1) give the appearance of a legal header and 2) be able to run with only a download until I'm ready for a PCV. (I'm going to run my bike with Rinehart slip-ons that I'm buying from a buddy.)

Nobody seems to have these. All I come up with is 18mm bungs, or adapters to fit 18mm sensors in a 12mm bung. I know that exhaust manufacturers like Jackpot and Thunderheader has them, but I doubt they'll sell them separately.

Any suggestions?

 

I'd spend some money on a dyno pull with gas analyzer to make sure things are right. I've read of possible crosstalk issues with the head pipes on the 10's being either modified (cat removed) or 09 in its place. I might be ditching the cat on my 2010 Triglide, I'm figuring on waiting to see how people make out with the new head pipe Fuelmoto has.

 

I know I'll be able to use the PCV with autotune when it comes out with the 18mm bungs, but I'd still like to use the 12mm sensors in case I decide to go with a SEST.
