I am about to receive delivery of my new (to me) Harley. (my 4th)
It's an '07 Streetbob (my 2nd) and it comes with V&H Big Radius 2 in 2 pipes. That's the only thing that was done. No new A/C, no fuel mgmt, etc.
The bike is about to be shipped and in the meantime the seller made a video and it sounds great. Doesn't seem to pop or anything and apparently it runs fine.
On my 1st '07 SB I ran V&H Shortshots with a Power Commander and was happy.
On my last bike, the Heritage in my sigpic, I ended up running a Supertrapp Supermeg 2 in 1 with a Power Commander and loved it.
I plan on eventually getting a Power Commander but I'm wondering if running the Big Radius without any other changes will make the bike run too hot and lean? Will it hurt the engine?
If it runs well enough I might not change at all but want to make sure there are no future problems.
I appreciate your feedback.
Thanks,
Steve

 

should be fine, running mine the same

 

It will be find but it will be a little lean. If you want to cool it down by richening it up a bit...I will be selling my XEID's for have price as I just got a tuner. You can see more info at nightrider.com on how they work

 

You are in absoloutely no danger until you open the air intake fuel/air wise.
@ ROOTI Someone will surely grab those xied's lol I've seen you offer them up twice!

 

Maddghost,
Sho nuff. I'm buying them from Rooti.
I'd been hearing about them and he gave me a good deal. I'll let you know how it goes.

 

you can run pipes safely. change the air cleaner with pipes and its a different story.

 

Actually on the newer EFI bikes you can do the pipes and ac without harming anything.....Amazing that people still think otherwise.

 

You are correct, the ECM will compensate to get it back to roughly the 14.6 AFR, so no harm will come to the bike.

I never cease to be amazed at all the myths and wives tales out there.

 

how new of a bike are we talking? i have an 06 FXDI, would i be able to change pipes and ac without a tune?

 

I believe 07, when they started using o2 sensors, don't think you have o2's on your TC88
