Again, FWIW, I run premium and I have the DK Custom breather, which is mounted mid-frame on the right side of the bike next to the exhaust. Maybe that's what I'm smelling, but I had the breather installed before changing the exhaust and I didn't smell exhaust fumes before the change. If I'm running rich, it's doing so because of the V&H custom map for the Pro Pipe, which has been auto-tuned. I think I'm going to contact V&H and have them look at my map. I haven't been paying attention to my mileage, so that's something I'll have to monitor. It's good to know I'm not the only one smelling exhaust fumes.
In the same boat. I have the Fuel Moto pro billet AC. Likely not the problem.
Again, I understand exhaust smell without having a CAT, but this seems more than that. Thanks.
I spoke with Fuel Moto today and they were very helpful. Yes it's running rich and likely how it's supposed to with my setup. However, the guy I spoke with was very explanatory and advised I send in for a slightly leaner map if I desire. Best part with the PowerVision and Fuel Moto...it's free and if it doesn't work, you can just flash back to the other tune. I'll update when I get the new tune.
If it is a raw fuel smell, you're too rich and want to adjust your tune.
But you mention it more of an exhaust smell. It could very well be that the oil that is venting back into your air cleaner is what you are smelling.
Many of the newer 103's are spitting a lot more oil through their breathers than previous years....AND they do it most at higher RPM's, and on heavy decel.
Not only is the smell bothersome, it is very bad for your engine (than the EPA and slipping HD tolerances).
The best solution is either an externally vented Air Cleaner System like an Outlaw 587, or to get an External Breather System for your current air Cleaner.
Most probably this is what you're smelling...and this is what it is doing to the inside of the engine.
Much of the oil that is getting fed from the breathers ends up in your filter element and in the throttle body, that is where the smell comes from...then the stuff that passes thru ends up forming deposits on your pistons, heads and valves.
If you use an EBS, then all that goes to the atmosphere BEHIND you, you don't smell it, and your engine thanks you.
Got the revised map by FuelMoto fairly quick. They evaluated the autotuned base map and found very minimal changes...leading to the conclusion the base map was fairly spot on. Nonetheless they sent me a revised map at my request (likely leaner). I flashed it today, ran 50 miles and then autotuned for 50 miles. Once I completed and flashed the new autotuned revised map I realized it wasn't running as well compared to the autotuned base map. So I flashed the autotuned base map back into the ECM and ran autotune again....ultimately obtaining pretty damn good results. The bike runs pretty good and the smell is likely just from having the CAT removed vs airflow on decel from the fairing.
I just want to update the thread. The bike runs good.
