My bike stinks... 2 Months ago  
whenever someone rides behind me. Was on a group ride and complaints made by riders behind me. Most likely the bike runs rich. Perhaps the carbed bike suffers from this as I rode behind a 06 Road Star and thought I was getting gassed by carbon monoxide. I rode behind a Harley and no issues from a 103 ci fuel injected bike. My 108 big bore was complained about as per puff of smoke when I opened it up and the general exhaust smell.

So I decided to ride tail in the group. I am not going to readjust the carb as the bike performs very well. Maybe carbed bikes burn more gas or have more emissions versus fuel injected. nonetheless, I may attend 3 group rides per season so I care less.

Is there a chance my bike burning oil? The puff of smoke may be gas due to HSR set up? Nonetheless I ride alone and it is not high on my to fix list. Thanks for any comments or advice.

Re:My bike stinks... 2 Months ago  
I just realized I rode behind my bike 2 weeks ago. I was riding a souped-up Dyna and my pal was riding my bike. It was a bit windy verses yesterday as the air was still. Nonetheless, 2 weeks ago we were hammering the bikes and I rode close behind the 108ci. I did notice the typical carbed bike exhaust, but nothing worst than yesterday behind an 06 Road Star.

When I group ride I expect the smell of exhaust. Actually felt gassed out riding in traffic by cagers. Could it be the people I ride with are not use to exhaust output? Noise and smell of other bikes do not bother me. It is all part of the ride. Even if the bike is running rich, I care less since the bike runs great. Maybe I'll get one of those exhaust units that tell me how much co2 is being spewed out.

I was surprised at the number of people put off by the oil smell, when doing the Erbman crankvent mod, versus running the line below the bike, and putting a filter on it.
I've noticed as soon as I ride by a dead sumthin or other in the ditch, that's all I can smell. Any oily vapor smell disappears immediately.

Re:My bike stinks... 2 Months ago  
I figured it out. The bike is running rich and the smell is akin to the same smell as the old gas burning muscle cars of the past. Getting roughly 200 km per fill up, The bike runs strong so I am leaving the HSR alone. I rarely group or buddy ride so the smell issue is a moot point. If I group ride, I will run tail gunner position. With what has been done to the engine as far as high performance mods, let sleeping dogs lie.

When I ride behind my pal with his 2006 Road Star it is like riding behind an old muscle car as far as monoxide fumes. Others commented about his bike smelling also. I noticed it too but it's part of riding and I care less about that type of stuff.

Usually I change something when someone complains but not altering the set up when it works right for the bike. I will get the bike serviced and get the exhaust tested for excessive emissions next spring and let a professional tune the bike, as my carb skills are rudimentary, and I do not have the equipment to do the proper tests.

Rode 198 miles round trip yesterday to get a box of Fried chicken. Wind chill was 8 f so it is getting cold. Fried chickens and motorcycles are a winning combination.

Maybe your buddies will chip in to get a hepafilter system for your exhaust

Every time you roll it on, the accelerator pump in enrichening the mixture with a raw stream of fuel that is in larger droplets than the fuel that is being drawn up through the emulsifier tubes on your pilot jet and your main jet holder. These larger droplets mostly break up during cylinder fill, but not completely, resulting in the raw gas smell. FI bikes increase the pulse duration of the injector to accomplish this enrichment, and the high pressure spray adequately reduces the droplet size to a burnable volume, so they are more efficient on the feed end. Additionally the O2 sensor feedback allows the ECU to trim the acceleration pulse width to the most effective and efficient fuel delivery. A carbed bike is an anvil in the hydraulic press world of FI.

You are riding a fossil. Be proud.

Re:My bike stinks... 2 Months ago  
That is a great explanation as to why carbed bikes and cars have the monoxide oversmell. When I rode behind the fuel injected Harley no smell what so ever. The old school carb, with it's excellent sounding loaping idle thanks to the cams, is great. I admit the bike is heavy on fumes.

When I start the bike with the choke engaged it reminds me of my old 1963 MGB and a 1968 390 ci. Mustang I owned many years ago. Those babies would make your eyes water, dry your throat, gas your cat and cause the next door neighbor to move.

+1 for Fuel injection, -1 carbed engine (unless you disliked your neighbor)

I told my wife I should nickname the bike "Old Stinky" but she frowned on that. I call my bike Old Duke. "Gonna take Old Duke for a tear, be back later."

I once said I am gonna take Old Stinky for a run, and she replied, why bother running, take your bike for a ride. When you come home I will have the tub filled for you.

Well, the mystery of the smelly bike is solved. Old school is cool but has to sit in the back of the class.
