Fuel processor for slip on's?

[jwg383]

Hey Guys,

When only adding slip on mufflers instead of a full exhaust system, is a fuel processor still needed for a proper tune? Would a processor be beneficial even with a stock bike?

Thanks for the knowledge

After market processors are still needed on a stock Nomad...

If you're just adding slip on mufflers, you do not need to add a fuel processor. You will however hear more popping on decel. A fuel processor with a proper map will all but eliminate that....and a fuel processor with an aftermarket air intake will create a lot more power...just sayin' :-)

Even just adding slip ons you need to install a fuel processor.The popping is telling you that your engine is running"LEAN". After a while the pipes will discolor, blue or brown and then possible major prolems
I just installed V&H slip-ons, Power Commander V and the Thunder K&N vertical air kit. Runs and sounds GREAT and no backfiring. Pay now or pay later!! Hope this helps.

After 68000 miles I could see no blue on the pipes...all w/o a fuel processor and slip-ons only. Wonder how long it would have taken for the blue to show up?

Not everyone has been so lucky!!

The popping is the reed valves. And I've never had a set of pipes (factory or otherwise) that haven't had at least a little bit of bluing (other than a set of Hard Kromes once but I think they're double walled pipes).

Stock 08 Nomad, I put a fuel processor on it to stop the pinging and after installing it the fan almost never came on.

Since then I have installed Chuckster's dual plate intake kit. My friend has a 07 stock nomad no processor. We rode in a small parade this past Saturday. Temp was 52 deg and it was slow because of the people walking my fan never came on and his never shut off.

Since I first posted this thread, I've added a set of Cobra billet tipped slip on's, a Cobra Power Pro tuner, and a K&N filter.
Bike runs great. The mods made a huge performance and rideability difference, BUT, the pipe tips are still blueing, it still pops on decel, and the fan still runs fairly often.
In my case, a tuner is not a cure all, but I'm still very happy with it.
